Q: What development languages are supported on Windows Phone 7?

A: Right now, the only development language supported is C#. Developers are also interested in Visual Basic, C++ and other .Net apps, Kindel acknowledged, and Microsoft may add support for these over time. But Microsoft’s development strategy for its new mobile platform is if you’re doing XAML programming, use Silverlight. If you’re doing an interactive or 3D game, go with XNA. The version of Silverlight supported is a superset of Silverlight 3 (not Silverlight 4, which is going to be released to the Web in final form in April.) The Community Technology Previews of the tools for the Windows Phone 7 platform are available as of March 15 for download.
