At MIX it was announced how to build games and apps for the Windows phone, developers at the conference are being introduced to the Windows Phone 7 Series development tools and given a tour of the platform, which uses both XNA Game Studio and Silverlight.
Announce was the availability of Visual Studio 2010 Express for Windows Phone, which is specifically designed for building Windows Phone applications and is now available free in a single download at www.developer.windowsphone.com. Visual Studio 2010 Express includes an emulator that will allow developers to build and test their applications directly on their PCs in a virtualized Windows Phone 7 OS environment. That means developers won’t need the phone hardware to get started at building phone apps.
