As just now, I heard about the Windows Phone 7 development. So I would like to know the following things regarding Windows Phone 7:
From where can I start with Windows Phone 7 development? What are the best books/article/code blog/tutorial, etc.
Which are the tools I should need/download to start with Windows Phone 7 development?
Update:
I found this very much helpful: http://www.devx.com/VS_2010/Article/45898/9851
You can get started by downloading the tools and registering to publish here: http://create.msdn.com/en-us/home/getting_started
There are a lot of very good tutorials out there. I recommend Channel9's Windows Phone 7 training course and Windows Phone 7 for the Absolute Beginner.
There's also a very good book available as a free PDF download: Programming Windows Phone 7 by Charles Petzold.
