Today, the final version of the Visual Studio Tools for Windows Phone 7 was released. To get started, download the final bits here. You may also want to go ahead and download the Silverlight Tools for Windows Phone 7 and the Windows Phone 7 Training Kit for Developers. I’m going to walk you through setting up your environment for development and create an application using the new Silverlight Tools for Windows Phone 7. Note this is everything you will need to develop applications for Windows Phone 7.
