Microsoft's Mix 10 conference starts from 15 March 2010 and continues to 17 March 2010. Among the topics covered will be Silverlight, XNA game development and the XAML based Windows Phone 7 design language
A full list of the sessions that will be covered can be found here
The XNA Framework, an implementation of the .Net, and its associated tools, also are likely to be part of the mix. Given the XNA Game Studio already supports Xbox 360, as well as the Zune media player, and Windows Phone 7 borrows so liberally from the Zune HD, in terms of its user interface) it makes sense XNA tools will support Windows Phone 7.
The Mix conference is sure to your web development and design skills to the next level, so don't miss out!
This past weekend Microsoft published specifics on the 12 Windows Phone 7 sessions for developers at its upcoming Mix 10 conference.
