…the WPSDK 7.1 didn’t run on the Windows 8 Consumer Preview release. The issue involved three elements: an issue with XNA Game Studio, an issue with the Windows Phone emulator, and a requirement for .NET 3.5. The only remaining blocker for folks successfully developing for Windows Phone on Windows 8 was the emulator. I’m happy to report that this patch removes that final roadblock, and enables our mobile developer community to bring their WPSDK with them as they evaluate the new OS.
