As you might know, Rob Miles and Andy Wigley have been talking Windows Phone 7 development in Live Meeting sessions. They've been covering how you write Silverlight applications, how you write games in XNA, how you sell them, and what makes this new platform so special and shiny. There were two sessions on Tuesday, July 20th and there will be two more on Thursday, July 22nd:

Session Three: Advanced Windows Phone Development

Session Four: Selling Your Windows Phone Solutions & Wrap Up

Today Rob and Andy answered loads of questions in an “Office Hours” session in the Windows Phone 7 Jump Start forum. Take a look.
