Microsoft has a video series to help developers get started with Windows Phone 7. Here’s the first by Nancy Strickland.

This video gets you set up with the developer tools and shows you how to build your first application. If you’re familiar with Visual Studio, it’s amazingly simple to build and debug WP7. If you haven’t seen it yet, the coolest thing in my opinion is the windows phone emulation. As explained in the video, the grab handles are slightly larger than the visuals because it represents the touch sensitive area. If you have a touch sensitive monitor, you can even touch touch your “windows phone” application as you’re debugging!

WP7 will be coming out soon, and it’s a good time to start making applications a brand new market. This video series will help you get started. After that, be sure to download the training kit and follow up with the windows phone blogs and forums.
