Here are links to the MIX10 conference sessions that are relevant for Windows Phone 7 Series developers from the first two days. Go to http://live.visitmix.com/videos to access all of the keynote & session videos from this year’s conference. There are tons of other session that are likely useful for Windows Phone developers, such as the Windows Azure talks and Silverlight 4 talks so we encourage you to view the whole list on the visitmix site.
Edit: I forgot the day 1 keynote – 2 hours long almost entirely about Windows Phone developement. Tons of GREAT demos of really cool 3rd party apps. Here’s the link to watch it streamed in high-def:
Edit (3/18/2010 6:36PM PST) – Added the rest of the sessions with links. A few videos are still not posted but the links are right and will work once the videos are posted.
