Tomorrow, it'll give a full session at the .NET Montreal Community about Windows Phone 7. In that session I'll give a full end to end overview of my experience building applications for Windows Phone 7. So I'll start with the idea through the development process and finally publishing the application to the marketplace.
If your interested, I’ll be also available to answers your question. I’ll also have a device so you can test and feel the new OS which is now available since November 8th.
