I’m not at Tech Ed in Orlando, but was ready to watch the Bill Gates keynote which this web site tells me starts at 8.30am Eastern – trouble is, that was 45 minutes ago, and the webcast still just plays a pretty tune and then stops. Not a great way to showcase Silverlight live streaming.

Fortunately the press release has gone up. Gates has announced Silverlight 2 beta 2 (this is the one with .NET runtime included), complete with a Go Live license. Microsoft has also released Expression Blend 2.5 June 2008 Preview and Microsoft Silverlight Tools beta 2 for Visual Studio 2008, so we should be all set to code and go.

Other highlights: IE 8 Beta 2 in August, new preview code of project “Velocity” for caching high-scale apps, and more hype for Oslo, Microsoft’s “unified modeling platform”:

Oslo will include visual modeling and composition tools, a foundational repository built on SQL Server 2008 for managing application metadata, and a new, declarative modeling language to enable interoperability of models between tools and domain-specific modeling notations.

I don’t doubt that Microsoft is serious about Oslo; others at Microsoft has confirmed that this is a major initiative. However, I am naturally sceptical about whether Oslo will achieve its goals. Most other grand model-driven development products have failed; why will this be different?
