Hands on with Xamarin 3.0: a cross-platform breakthrough for Visual Studio

Today Xamarin announced version 3.0 of its cross-platform mobile development tools, which let you target Android and iOS with C# and .NET. I have been trying a late beta preview.

In order to use Xamarin 3.0 with iOS support you do need a Mac. However, you can do essentially all of your development in Visual Studio, and just use the Mac for debugging.

To get started, I installed Xamarin 3.0 on both Windows (with Visual Studio 2013 installed) and on a Mac Mini on the same network.

image

Unfortunately I was not able to sit back and relax. I got an error installing Xamarin Studio, following which the installer would not proceed further. My solution was to download the full DMG (Mac virtual disk image) for Xamarin Studio and run that separately. This worked, and I was able to complete the install with the combined installer.

When you start a Visual Studio iOS project, you are prompted to pair with a Mac. To do this, you run a utility on the Mac called Xamarin.IOS Build Host, which generates a PIN. You enter the PIN in Visual Studio and then pairing is active.

image

Once paired, you can create or open iOS Storyboard projects in Visual Studio, and use Xamarin’s amazing visual designer.

image

Please click this image to open it full-size. What you are seeing is a native iOS Storyboard file open in Visual Studio 2013 and rendering the iOS controls. On the left is a palette of visual components I can add to the Storyboard. On the right is the normal Visual Studio solution explorer and property inspector.

The way this works, according to what Xamarin CEO Nat Friedman told me, is that the controls are rendered using the iOS simulator on the Mac, and then transmitted to the Windows designer. Thus, what you see is exactly what the simulator will render at runtime. Friedman says it is better than the Xcode designer.

“The way we do event handling is far more intuitive than Xcode. It supports the new iOS 7 auto-layout feature. It allows you to live preview custom controls. Instead of getting a grey rectangle you can see it live rendered inside the canvas. We use the iOS native format for Storyboard files so you can open existing Storyboard files and edit them.”

I made a trivial change to the project, configured the project to debug on the iOS simulator, and hit Start. On the Mac side, the app opened in the simulator. On the Windows side, I have breakpoint debugging.

image

Now, I will not pretend that everything ran smoothly in the short time I have had the preview. I have had problems with the pairing after switching projects in Visual Studio. I also had to quit and restart the iOS Simulator in order to get rendering working again. This is an amazing experience though, combining remote debugging with a visual designer on Visual Studio in Windows that remote-renders design-time controls.

Still, time to look at another key new feature in Xamarin 3: Xamarin Forms. This is none other than our old friend XAML, implemented for iOS and Android. The Mono team has some experience implementing XAML on Linux, thanks to the Moonlight project which did Silverlight on Linux, but this is rather different. Xamarin forms does not do any custom drawing, but wraps native controls. In other words, it like is the Eclipse SWT approach for Java, and not like the Swing approach which does its own drawing. This is keeping with Xamarin’s philosophy of keeping apps as native as possible, even though the very existence of a cross-platform GUI framework is something of a compromise.

I have not had long to play with this. I did create a new Xamarin Forms project, and copy a few lines of XAML from a sample into a shared XAML file. Note that Xamarin Forms uses Shared Projects in Visual Studio, the same approach used by Microsoft’s Universal Apps. However, Xamarin Forms apps are NOT Universal Apps, since they do not support Windows 8 (yet).

image 

In a Shared Project, you have some code that is shared, and other code that is target-specific. By default hardly any code is shared, but you can move code to the shared node, or create new items there. I created XamFormsExample.xaml in the shared node, and amended App.cs so that it loads automatically. Then I ran the project in the Android emulator.

image

I was also able to run this on iOS using the remote connection.

I noticed a few things about the XAML. The namespace is:

xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"

I have not seen this before. Microsoft’s XAML always seems to have a “2006” namespace. For example, this is for a Universal App:

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x=http://schemas.microsoft.com/winfx/2006/xaml

However, XAML 2009 does exist and apparently can be used in limited circumstances:

In WPF, you can use XAML 2009 features, but only for XAML that is not WPF markup-compiled. Markup-compiled XAML and the BAML form of XAML do not currently support the XAML 2009 language keywords and features.

It’s odd, because of course Xamarin’s XAML is cut-down compared to Microsoft’s XAML. That said, I am not sure of the exact specification of XAML in Xamarin Forms. I have a draft reference but it is incomplete. I am not sure that styles are supported, which would be a major omission. However you do get layout managers including AbsoluteLayout, Grid, RelativeLayout and StackLayout. You also get controls (called Views) including Button, DatePicker, Editor, Entry (single line editor), Image, Label, ListView, OpenGLView, ProgressBar, SearchBar, Slider, TableView and WebView.

Xamarin is not making any claims for compatibility in its XAML implementation. There is no visual designer, and you cannot port from existing XAML code. The commitment to wrapping native controls may limit prospects for compatibility. However, Friedman did say that Xamarin hopes to support Universal Apps, ie. to run on Windows 8 as well as Windows Phone, iOS and Android. He said:

I think it is the right strategy, and if it does take off, which I think it will, we will support it.

Friedman says the partnership with Microsoft (which begin in November 2013) is now close, and it would be reasonable to assume that greater compatibility with Microsoft XAML is a future goal. Note that Xamarin 3 also supports Portable Class Libraries, so on the non-visual side sharing code with Microsoft projects should be straightforward.

Personally I think both the Xamarin forms and the iOS visual designer (which, note, does NOT support Xamarin Forms) are significant features. The iOS designer matters because you can now do almost all of your cross-platform mobile development within Visual Studio, even if you want to follow the old Xamarin model of a different, native user interface for each platform; and Xamarin Forms because it enables a new level of code sharing for Xamarin projects, as well as making XAML into a GUI language that you can use across all the most popular platforms. Note that I do have reservations about XAML; but it does tick the boxes for scaling to multiple form factors and for enormous flexibility.

Hands on with Cordova in Visual Studio

At TechEd this week, Microsoft announced Apache Cordova support in Visual Studio 2013. A Cordova app is HTML and JavaScript wrapped as a native app, with support for multiple platforms including iOS and Android. It is the open source part of Adobe’s PhoneGap product. I downloaded the preview from here and took a quick look.

There is a long list of dependencies which the preview offers to install on your behalf:

image

and

image

The list includes the Java SDK, Google Chrome and Apple iTunes. The documentation explains that Java is required for the Android build process, Chrome is required to run the Ripple emulator (so you could choose not to install if you do not require Ripple), and iTunes is required for deploying an app to an iOS device, though a Mac is also required.

The license terms for both Chrome and iTunes are long and onerous, plus iTunes is on my list of applications not to install on Windows if you want it to run fast. Chrome is already installed on my PC, and I unchecked iTunes.

Next, I ran Visual Studio and selected a Multi-Device Hybrid App project (I guess “Cordova app” was rejected as being too short and simple).

image

An annoyance is that if you use the default project location, it is incompatible because of spaces in the path:

image

The project opened, and being impatient I immediately hit Run.

When you build, and debug using the default Ripple emulator (which runs in Chrome, hence the dependency), Visual Studio grabs a ton of dependencies.

image

and eventually the app runs:

image

or you can debug in the Android emulator:

image

A good start.

Microsoft has some sample projects for AngularJS, BackboneJS and WinJS. This last is intriguing since you could emulate the Windows Phone look and feel (or something like it) on Android on iOS, though it would look far from native.

The preview is not feature-complete. The only supported device targets are Android 4.x, IOS 6 and 7, Windows 8.x Store apps, and Windows Phone 8.x. Windows Phone debugging does not work in this preview.

Brief reflections on 50 years of BASIC

2 Comments

Beginner’s All-Purpose Symbolic Code (BASIC) has turned fifty, as reported on The Reg and by Jack Schofield on ZDNet. A great moment in computer history, or would we have been better off without it?

My first computer (a Commodore PET) ran Basic from ROM, and without it you could do nothing, though developers bypassed it by using the POKE command to write low-level instructions into memory. The language is meant to be forgiving (as far as a computer language can be) and English-like, at the expense of being a little more verbose. It is case-insensitive and does not require braces or semi-colons to indicate blocks or lines of code, which makes programming look less intimidating for beginners.

I graduated onto an Atari ST, for which there was an excellent Basic implementation called GFA Basic, fast and capable. This was great for writing utilities, though, though serious programming tended to use one of several strong C compilers: Lattice C, Mark Williams C, HiSoft C come to mind.

Basic also had a role, even on the ST, as a macro language for applications. For example, the Superbase database manager used a version of Basic.

The company most strongly associated with Basic though is Microsoft. A version of Basic came with MS-DOS.

image

Microsoft also supported Basic for professional development. Microsoft Basic Professional Development System 7.x was a well-regarded development tool for business applications, though commercial shrink-wrap software tended to be written in C or C++.

That trend followed through to the Windows graphical environment. Visual Basic (VB), which made it easy to code Windows applications, was perhaps the most significant Basic release in terms of its impact, especially when it reached version 3.0 with full database support. Its popularity was such that many developers felt wounded when Microsoft discontinued Visual Basic 6.0, a direct successor, in favour of Visual Basic .NET which is something incompatible and different.

Further, VB 6.0 or something very like it lives on today, in the form of Visual Basic for Applications as found in all recent versions of Microsoft Office.

image

Despite this, Basic is in decline. Most of the professional developers I meet at events like Build use C# in preference to Visual Basic, there being little reason not to. C# is the premier language of .NET, and Visual Basic gets in the way if you want to keep up with latest .NET developments. Xamarin, which lets you code in .NET for iOS and Android, supports C# but not Visual Basic. Once you come to terms with semi-colons, braces and case-sensitivity, there is no real advantage to Visual Basic and C# is no more difficult.

I do see Visual Basic still used in education though, as well as by some developers who either prefer the language or are so used to it that they see no need to change; and to be fair, Xamarin aside, there is little if anything you can do in C# that you cannot also do in VB and the output is more or less the same.

The Roslyn project, which will be part of the next version of C# and probably in the next release of Visual Studio, lets you paste C# code as VB and vice versa.

Nevertheless, I believe we will see further decline in Basic usage, especially as it is little used outside Microsoft’s platform.

Would it have been better if Microsoft has not adopted Basic so wholeheartedly? There are some problems with Basic, though it is possible to write excellent code in Basic just as you can write poor code in C#, Python, C, or other more fashionable languages. Some issues:

  • Early versions of Basic encouraged badly structured programming with keywords like GOTO and GOSUB resulting in intricate loops that were hard to follow or debug.
  • Basic abstracts how software works to such an extent that you do not learn some important programming concepts such as pointers, addresses, memory allocation.
  • There is no natural progression from Basic to the C-like languages which dominate computing (C,C++,JavaScript,C#).
  • Visual Basic encourages developers to mix GUI code and business logic in the same files, as well as building user interfaces that tend not to scale well.
  • Small and declining professional use means that Basic is less useful than many other languages in the job market.

That said, Basic powers many excellent business applications as well as introducing many to the wonders of programming, and deserves our respect.

Microsoft completes Nokia acquisition: what now for Windows Phone?

Microsoft has completed its acquisition of Nokia today, a milestone in the turbulent story both of Nokia and of Windows Phone, which Nokia adopted in the hope of establishing a “third ecosystem” to challenge Apple iOS and Google Android.

Rumour has it that the Nokia acquisition was controversial within Microsoft and a large factor in the departure of Steve Ballmer as CEO. However, even if Microsoft took the view that an independent Nokia was better for Windows Phone, it faced the risk that market pressure would drive Nokia to Android and weaken the platform. The beginnings of that process may have been under way, with the launch of the Nokia X Android-but-not-Google range of phones, but we will never know, since Microsoft decided on acquisition.

image

How important has Nokia been for Windows Phone? In my view, life-saving. Before Nokia, there was no manufacturer nor operator which really cared about the platform, and it showed in lacklustre hardware and half-hearted marketing efforts. Nokia came up with the distinctive Lumia brand and style, added a decent mapping service, and with its focus on the PureView camera technology, gave enthusiasts a reason to take a close look at its devices. It also saw an opportunity at the low end, and created some great value devices that opened up a new market for the operating system.

There were some blunders (the original Lumia 800 suffered many faults and terrible battery life on launch) and Lumia did not grow fast enough to restore Nokia to health, but to my mind it was a good effort.

Today, the general opinion of Windows Phone is that it is a strong smartphone operating system but suffers from a lack of high-quality apps. Users have to put up with the fact that most app vendors feel they are done if they support iOS and Android; and if there is a Windows Phone version of their app, it is often poor. That is not a great position for Microsoft/Nokia to be in, but it could be worse. Blackberry 10, which is also a decent mobile operating system, has been all-but written off as a viable contender.

Microsoft is fortunate in that, unlike Blackberry, it can to some extent create its own ecosystem. Office 365, Bing, OneDrive, Nokia’s maps, Azure for developers needing a cloud back-end: taken together they form a viable alternative. In this respect, Microsoft actually has an advantage over Apple, which lacks this breadth of services.

I have been reading the latest Developer Economics report from Vision Mobile. It is a good example of the neutral perspective on Windows Phone, though you will find it somewhat inconsistent:

Windows Phone sales picked up significantly in Q3 2013, showing a 140% increase year-on-year, fuelled primarily by low-end device sales. According to Kantar, Windows Phone sales in the three months running to Oct 2013, reached double-digit figures in some Western European markets. While this is certainly a positive sign for Microsoft they will continue facing an uphill struggle, in an increasingly unfavourable race against the two runaway leaders, iOS and Android.

The report emphasises that iOS and Android have won the mobile OS wars, but says that there are signs of hope for Microsoft:

Windows Phone Developer Mindshare has finally moved upwards, following positive market signals in the last two quarters. As we have frequently highlighted in past reports, the developer intent has always been there, with Windows Phone figuring at the top of our Developer Intentshare chart, but needed positive market signs in order to convert this interest into Mindshare. While the 26% Developer Mindshare is still less than half of that for iOS, Microsoft can now claim that over a quarter of developers that target mobile platforms are now actively developing for Windows Phone. […]

As a latecomer to a mobile market dominated by strong network effects, establishing a credible footprint in mobile remains a formidable challenge
for Microsoft. We believe that Microsoft may be better served in the long-run by leveraging the Android ecosystem as the deployment platform for Office
and Server businesses which are still growing.

Microsoft is in fact supporting iOS and Android as clients for its cloud services, as noted again at yesterday’s financial webcast, where CEO Satya Nadella talked about a strategy that goes across “devices some ours, some not ours.” It is a bit of both though, and the company is not showing any signs of weakening its own mobile efforts.

In my view reports like that from Vision Mobile miss a couple of factors. One is that Windows and Windows Phone are converging. They already use the same OS kernel, and at the Build conference earlier this month Microsoft announced Universal Apps that will run on both, and the ability for developers to sell an app once and have users install on both phone and full Windows.

This means that the future of Windows Phone and that of Windows itself are closely bound together. Longer term, they will either both fade away, or both succeed.

Windows remains a huge business for Microsoft, despite the decline of the PC, especially in business. Microsoft’s problem though is that adoption of Windows 8 has been relatively weak, and that those who do use it, largely live in the desktop environment rather than running Store apps (of which Universal Apps are a variant).

Despite the dismal progress so far for the Store apps platform and ecosystem, I believe it should be taken seriously. On paper it has many advantages, not only for touch control, but also in deployment, security, roaming data driven by the cloud, and discoverability through the store. Isolation from the core operating system protects users against the things that destroy desktop Windows, like unwanted extras foisted on users who simply need to update Java or Flash.

At Build we saw not only Universal Apps, but also a preview of Office in the Windows Runtime (Store app) environment. We also saw a preview of Store apps running within a window in the desktop environment, solving the jarring transition between desktop and Store app environments that unsettles users. If Microsoft gets this right, both Windows Phone and Windows tablets will be substantially more attractive.

Microsoft also has the ability to bind Windows Phone into its enterprise device management environment, System Center and InTune. In Windows Phone 8.1 the device management and security features businesses need are much improved. More is still needed; but the company should be able to build integration points that make it attractive to business customers already using products such as Active Directory, Microsoft Office, Office 365, System Center or InTune.

Another factor is the strength of Visual Studio for developers, especially as Microsoft improves its integration with cloud services like Azure and Office 365. You can use C# everywhere from cloud or server to mobile client.

image

Cortana is sure that Windows Phone is the best; but check out the Bing ad.

What then is the future of Windows Phone? Uncertain, as ever; but if Microsoft pulls off a smooth Nokia acquisition – leaving in place the things that enabled the company to build the Lumia brand – and if it delivers on the promise we saw at Build, of a strong unified platform, then I expect market share to continue to grow. If it can climb to 10% or 15%, it will be on the map for vendors and the app problems will ease.

On the other hand, if Microsoft/Nokia means a return to the ineffective marketing and strategy we saw before Nokia adopted Windows Phone, then I expect Windows Phone to follow Blackberry into oblivion.

I am positive, but Microsoft needs to execute carefully and quickly to win market share for its mobile platform.

A little bit of magic from Adobe PhoneGap: instant app preview on a device

Adobe has released an update to its PhoneGap tools (build mobile apps using HTML and Javascript) which enabled instant preview on a device. You don’t need to compile and deploy; it is enough simply to save your changes using a text editor, and the running app preview on the connected device will refresh.

I tried a quick demo on Windows 8. PhoneGap installation or update is easy since it uses the node.js package manager: open a node command line and type npm install –g phonegap.

I had to update the Android SDK to version 19, which was the usual tedious update using the Android SDK Manager, but also worked smoothly.

Then I created a PhoneGap app and ran it in the emulator. So far so goo.

Next, I went to an Android phone and installed the PhoneGap Developer App.

image

Back on the PC, I started the built-in web server that serves the app refreshes to the device. Simply navigate to the app folder in the node command line and type: phonegap serve

Then on the device I ran the PhoneGap Developer App, and connected to the PhoneGap development server (IP no and port). The app preview appeared on the phone.

I then used Notepad to change the app home page slightly. Saved. The app preview refreshed almost instantly.

image

Here it is on the device:

A cool feature, though with some limitations. See Raymond Camden’s post for a few more details.

Currently iOS and Android are supported, with Windows Phone coming soon.

Windows problems: new users cannot log in, SQL Server 2014 install fails

Two issues I have seen recently:

1. A Windows 7 laptop which belonged to a developer and was being passed on to a new user. However, although you could create the new user, you could not log in as that user. The error was “User Profile Service service failed the logon. User profile cannot be loaded.”

I narrowed the problem down to an “Access denied” error when trying to create the profile, but we decided to restore Windows to factory settings (using recovery tools) since that was probably a better approach for the new user anyway – you never know what a developer may have tweaked or installed in Windows!

2. SQL Server 2014 Database Engine installation failing on Windows 8. The reported error: Could not find the Database Engine startup handle.

Annoyingly, you cannot attempt a repair install if you get this, since repair cannot run if there has not been a successful install in the first place. However this error does not rollback the installation, so you have the feature installed but not working. You have to remove the SQL Server feature using control panel, then you can retry. I got this on a couple of machines, tried a few things but failed, so used fresh VMs instead.

Others have run into this and there is a solution, which applies to both problems. They are actually the same, since SQL Server 2014 creates a new profile in the default install.

This solution means resetting the permissions on c:\users\default so that they are replaced with permissions inherited from the parent folder. This solution works; but it is not perfect, since these are the wrong permissions for the folder (too loose). Someone has done the job of finding the correct permissions for Windows 7. Applying all these is arduous though, and things may possibly have changed with updates since. In a production environment it would be better to narrow down the exact permission that is wrong, or to do a system restore.

If you are happy to risk it, navigate to c:\users in Windows Explorer and find the Default folder. This is hidden by default; you can make it visible using the View Options in Explorer; on the View tab choose Show hidden files, folders and drives. Next, right-click the c:\users\Default folder and choose Properties, then the Security tab, then Advanced, then click Change Permissions. Check the box:

Replace all child object permission entries with inheritable permission entries from this object

Click OK – it does not take long – and now new users can log in, and the SQL Server 2014 setup runs OK.

image

The problem seems to be common so it is likely that either an official update or a commonly-used third-party install is breaking these permissions. I would be glad to know what it is; it would also be good if Microsoft would build into Windows a feature that would restore default permissions for a system folder like this one.

Update: It may be sufficient to delete a single file. See this thread where event logs lead to a sqmdata…sqm file that, when deleted, fixed the issue. Check the Windows Application log for event 1509.

Hands on: SQL Server 2014 with data files in Azure Blob Storage

2 Comments

One intriguing new feature in Micrsosoft’s SQL Server 2014 is the ability to create or attach databases whose files are in Azure blog storage. This sounds like something that would not work at all well: why would you want a database engine to mount files located hundreds or thousands of miles away? However, the feature is apparently baked deeply into SQL Server, according to this white paper (which is essential reading if you want to know more):

SQL Server 2014 integration with Windows Azure blob storage occurs at a deep level, directly into the SQL Server Storage Engine; SQL Server Data Files in Windows Azure is more than a simple adapter mechanism built on top of an existing software layer.

· The Manager Layer includes a new component called XFCB Credential Manager, which manages the security credentials necessary to access the Windows Azure blob containers and provides the necessary security interface; secrets are maintained encrypted and secured in the SQL Server built-in security repository in the master system database.

· The File Control Layer contains a new object called XFCB, which is the Windows Azure extension to the file control block (FCB) used to manage I/O against each single SQL Server data or log file on the NTFS file system; it implements all the APIs that are required for I/O against Windows Azure blob storage.

· At the Storage Layer, the SQL Server I/O Manager is now able to natively generate REST API calls to Windows Azure blob storage with minimal overhead and great efficiency; in addition, this component can generate information about performance counters and extended events (xEvents).

It also seems that the main target usage is SQL Server running on Azure VMs in the same region as the blog storage, removing latency concerns, though the wording of the explanation is curious, implying almost that on-premise connection is supported but should not be:

Although it is theoretically possible and officially supported, using an on-premises SQL Server 2014 installation and database files in Windows Azure blob storage is not recommended due to high network latency, which would hurt performance; for this reason, the main target scenario for this white paper is SQL Server 2014 installed in Windows Azure Virtual Machines (IaaS). This scenario provides immediate benefits for performance, data movement and portability, data virtualization, high availability and disaster recovery, and scalability limits.

If you use blob storage in this way on an Azure VM, then I/O goes through the Virtual Network Driver, whereas an Azure data disk uses the Virtual Disk Driver. This nicety may be the main reason to consider the feature.

I tried both scenarios: on-premise and from an Azure VM. I had some difficulty getting started, despite this seemingly exhaustive tutorial. I followed it, I thought, to the letter, but got either the error:

Unable to open the physical file "https://myaccount.blob.core.windows.net/sqldata/azuredb.mdf". Operating system error 86: "86(The specified network password is not correct.)".

or else

CREATE FILE encountered operating system error 1117(The request could not be performed because of an I/O device error.) while attempting to open or create the physical file https://myaccount.blob.core.windows.net/sqldata/azuredb.mdf

The problem turned out to relate to the Shared Access Signature required. The supposedly exhaustive tutorial merely refers you to the CloudBlobContainer.GetSharedAccessSignature method in the Azure SDK and offers an incomplete code snippet. I wrote C# code for this and was able to generate a Shared Access Signature but it did not work (see above). I found myself in the depths of the Azure SDK, wondering if I should use version 2.1 or 3.0, and whether I should use Microsoft.WindowsAzure.StorageClient.CloudBlobClient or Microsoft.WindowsAzure.Storage.Blob.CloudBlobClient. The tutorial is also not clear about exactly which part of the Shared Access Signature you should store in the SQL Server Credential Manager; it is a multipart string separated by ampersands.

I have still not fully worked it out, but discovered the very helpful Azure Storage Explorer on CodePlex. If you follow the instructions in the white paper referenced above, and use the Azure Storage Explorer to generate the Shared Access Signature, then it works. The project is open source, so with a little effort it should be possible to find and document the exact requirements.

image

I tried creating and using a database from my on-premise SQL Server 2014 and I find the performance remarkably good, considering. There is no doubt some smart caching going on under the covers. Selecting 1000 rows from a table took 11 seconds the first time, and was instant the second time. It seems to me viable, on my brief look, though I am not sure why you would want to do this. However it is a good demonstration of how cloud and on-premise are coming ever-closer.

image

Running from an Azure VM in the same region is a different case, though I would suggest detailed and intensive testing before going into production.

Microsoft Build 2014: what happened

2 Comments

It’s curious. Microsoft’s new CEO Satya Nadella has been in place for only a month which means that almost everything announced at Build, Microsoft’s developer conference which took place last week in San Francisco, must have been set before he was appointed; yet there was a sense of “all things new” at the event, as if he had overseen a wave of changes.

The wave began the previous week, with the simultaneous announcement and delivery of Office for iPad. The significance of this is threefold:

  • It demonstrated Microsoft’s decision to give first-class support to mobile platforms other than Windows
  • It demonstrated that Office can be redesigned to work nicely on a tablet
  • The quality of the product exceeded expectations, showing that in the right circumstances Microsoft can do excellent non-Windows software

image

Next came Build itself. It was a tale of two keynotes. The first was all about Windows client – both Phone and PC. The core news is the arrival of the Windows Runtime  (WinRT, the engine behind Metro/Store Apps) on Windows Phone 8.1. This means that WinRT is now the runtime that developers should target for apps that run across phone and desktop – and even, we were shown, Xbox One, which will support WinRT apps written in HTML and WinJS (Microsoft’s JavaScript library for Windows apps).

In support of this, Microsoft announced a new Universal App project for Visual Studio, which lets you share both visual and non-visual code across multiple targets. How much is shared is a developer choice.

There is more. A Universal App is now (kind-of) a desktop app as well as a Store app, since in a future free update to Windows 8, it will run on the desktop within a window, as well as appearing in the Start menu on the desktop. We were even shown this; apparently it is a mock-up. This was the biggest surprise at Build.

image

What did Executive VP Terry Myerson say about this? Here is the exact quote:

We are going all in with this desktop experience, to make sure your applications can be accessed and loved by people that love the Windows desktop. We’re going to enable your Universal Windows applications to run in a window. We’re going to enable your users to find, discover and run your Windows applications with the new Start menu. We have Live Tiles coming together with the familiar experience customers are looking for to start and run their applications and we’ll be making this available to all Windows 8.1 users as an update. I think there will be a lot of happy people out there.

This is significant. When Myerson says, “we are going all in with this desktop experience”, he does not mean backtracking on Windows Store apps, to return to desktop windows apps (Win32 or WPF) as the future of Windows development. Rather, he means Windows Store apps integrated into the desktop.

There is a further twist to this. Windows Store apps are sandboxed and cannot communicate with each other or with the operating system other than via carefully designed and secured paths. This is in general a good thing, but restrictive for businesses designing line of business apps. It also means that legacy code cannot be carried over into a Store app, other than by full porting.

In the just-released Windows 8.1 Update this has changed. Side-loaded apps (in other words, not deployed from the Windows Store) can now escape the sandbox thanks to Brokered Windows Runtime Components. There are some limitations (32-bit only on the desktop side, for example) but this will make it possible to implement business applications as Store apps even if they need to interact with existing desktop applications or services.

There is still a huge blocker to Store apps from a business perspective, which is that you need Windows 8. Still, my guess is that once the update with the restored Start menu appears, most of the objections to Windows 8 will melt away.

We also saw Office for the Windows Runtime, which will run on both Phone and PC. It is written, I discovered later, in XAML, DirectX and C++ (“Blazingly fast”, we were told). Corporate VP Kirk Koenigsbauer introduced a preview of this, or at least PowerPoint.

image

No detail yet, and several references to “early code” suggest to me that this is a year or more away from full release (giving Office on iPad a big head start); but it will come. Koenigsbauer did not call it cut-down; in fact, it was instanced as proof that WinRT is suitable for large-scale apps, so I would expect something more complete than Office on iPad; yet it is hard to imagine things like the VBA macro language appearing here in its current form (VBA is based on the ancient Visual Basic 6.0 runtime), so there will be some major differences.

We also saw Windows Phone 8.1, including the Cortana virtual personal assistant who responds to voice input. For me other things in Windows Phone 8.1 are more significant, including new swipe-style keyboard for fast text input, VPN, S/MIME secure email, and a new notification centre. Unlike touch Office, Windows Phone 8.1 is coming soon; Nokia’s Stephen Elop (soon to be in charge of Windows Phone at Microsoft) said that the first 8.1 Lumia devices could be out from May, depending on territory, and that all Lumia Windows Phone 8 devices will get the update in the summer.

On to day two, which was Cloud day, though we also got significant .NET developer news.

Executive VP Scott Guthrie introduced a new portal for Microsoft Azure, the cloud platform. This is not just a new look, but integrates with Visual Studio online so you can easily view and edit the code and track team projects. There are also new monitoring and analytics features so you can check page views, page load time, browser usage and more. Guthrie also announced integration with Puppet and Chef for deployment automation.

Language designer Anders Hejsberg also came on stage. He announced the release version of TypeScript, a “typed superset of JavaScript” which is suitable for large applications. He also announced a new preview release of the compiler project code-named Roslyn, and on stage pushed the button that published it as open source. What is Roslyn? It is the next generation compiler for C# and VB, and is itself written in C#. This enables compiler and workspace APIs, which in turn enable rich editor features:

The transition to compilers as platforms dramatically lowers the barrier to entry for creating code focused tools and applications. It creates many opportunities for innovation in areas such as meta-programming, code generation and transformation, interactive use of the C# and VB languages, and embedding of C# and VB in domain specific languages.

Roslyn will be fully released in the next version of Visual Studio, for which we do not yet have a date. Roslyn will be delivered alongside C# 6.0.

There is also a new .NET Foundation which will oversee open source projects for .NET, with backing from folk including Xamarin’s Miguel de Icaza and Umbraco’s Niels Hartvig. It is all a bit vague at the moment:

In the upcoming months, the .NET Foundation will be inviting many companies and community leaders to join the foundation, including its Board of Directors and will then finalize its operational details, including governance models for its open source initiatives, membership structure and industry and community engagement.

Another significant event in the .NET story is the arrival of true native code compilation for .NET, although currently only for 64-bit Store apps. More on this soon.

A couple of events during Build caught my eye. One was de Icaza’s session on using C# to build for iOS and Android, not so much for the content itself (though there was nothing wrong with it), but rather for the huge attendance it drew.

The session was moved to the Build keynote room, and while there were spare seats, the room felt well filled. This speaks loudly about the importance of those platforms even to Microsoft platform developers, as well as of Microsoft’s support of Xamarin’s work.

Another was the appearance of John Gruber, author of the Daring Fireball blog and an Apple enthusiast. He appeared in a video during the keynote, explaining how a project in which he is involved uses Azure for back-end services, and then in person at another session, interviewing journalist Ed Bott about what is changing at Microsoft.

Gruber seems to me representative of a group of smart observers who have not in general been impressed with Microsoft’s endeavours over the past few years; but he for one is now more positive on the subject. Windows Phone is much better than its market share suggests, he said. This alongside Azure and a new openness to supporting third-party clients has made him look more favourably on the company.

My summary is this. On the Windows client side, Microsoft is taking its unpopular Windows release and its minority Phone platform and making them better and more compatible with each other, making sense of the client platform in a way that should result in growth of the app ecosystem both on Phone and PC/Tablet. On the cloud side, the company is building Azure and Office 365 (two platforms united by Azure Active Directory) into a one-stop platform that is increasingly compelling. The result was a conference and a direction that was largely welcomed by those in attendance, as far as I could tell.

That does not mean that the PC will stop declining, or that iOS and Android will become less dominant in mobile. There is progress though, and more clarity about the direction of Microsoft’s platform than we have seen for some years.

Microsoft CEO Satya Nadella introduces Microsoft Office for iPad, talks up Azure Active Directory and Office 365 development

New Microsoft CEO Satya Nadella has announced Office for iPad at an event in San Francisco. Office General Manager Julie White gave a demo of Word, Excel and Powerpoint on Apple’s tablet.

White made a point of the fidelity of Office documents in Microsoft’s app, as opposed to third party viewers.

Excel looks good with a special numeric input tool.

Office will be available immediately – well, from 11.00 Pacific Time today – and will be free for viewing, but require an Office 365 subscription for editing. I am not clear yet how that works out for someone who wants full Office for iPad, but does not want to use Office 365; perhaps they will have to create an account just for that purpose.

There was also a focus on Office 365 single sign-on from any device. This is Azure Active Directory, which has several key characteristics:

1. It is used by every Office 365 account.

2. It can be synchronised and/or federated with Active Directory on-premise. Active Directory handles identity and authentication for a large proportion of businesses, small and large, so this is a big deal.

3. Developers can write apps that use Azure Active Directory for authentication. These can be integrated with SharePoint in Office 365, or hosted on Azure as a separate web destination.

While this is not new, it seems to me significant since new cloud applications can integrate seamlessly with the directory already used by the business.

Microsoft already has some support for this in Visual Studio and elsewhere – check out Cloud Business Apps, for example – but it could do more to surface this and make it easy for developers. Nadella talked about SDK support for iOS and other devices.

Microsoft hardly mentioned Android at the event, even though it has a larger market share than iOS. That may be because of the iPad’s popularity in the enterprise, or does it show reluctance to support the platform of a bitter competitor?

Microsoft is late with Office for iPad; it should perhaps have done this two years ago, but was held back by wanting to keep Office as an exclusive for Windows tablets like Surface, as well as arguments with Apple over whether it should share subscription income (I do not know how that has been resolved).

There was also a brief introduction to the Enterprise Mobility Suite, which builds on existing products including Azure Active Directory, InTune (for device management) and Azure Rights Management to form a complete mobility management suite.

Nadella made a confident performance, Office for iPad looks good.

What is coming up at Build, Microsoft’s developer conference next week? Nadella said that we will hear about innovations in Windows, among other things. Following the difficulties Microsoft has had in marketing Windows 8, this will be watched with interest.
