I have just com across Mono Tools, a Novell add-in for Visual Studio that lets you test Mono compatibility. It adds a Mono menu which has options to run locally or remotely in Mono, analyze for compatibility issues, and create deployment packages. No sign of Mac support, which is a missed opportunity, but understandable given that Novell owns SUSE Linux.

For those few still unfamiliar with Mono, it is an open source implementation of Microsoft’s .NET Framework, enabling your .NET applications to run on other platforms. One compelling use is to have your ASP.NET web applications run on the free Apache web server, rather than Microsoft’s IIS.

Mono Tools works with both Windows Forms and web projects.

This is just the sort of thing Mono needs to move it further into the mainstream, though another less welcome sign of business acceptance is that this is a commercial product, currently costing $99.00 for an individual or $249.00 per seat in an organization. There is also an Ultimate edition at $2,499, which comes with a commercial non-LGPL license to redistribute Mono.

The Mono Tools team is now looking for testers for its 1.1 edition, which supports Visual Studio 2010.
