Here’s an excerpt from the introduction:
Developers are the heart and soul of any platform release—the very definition of a successful release is the large number of developers deploying applications and services on it. Microsoft has always focused on providing the best development experience for a range of platforms—whether established or emerging—with Visual Studio, and that continues for cloud computing. Microsoft added direct support for building Windows Azure applications to Visual Studio 2010 and Visual Web Developer 2010 Express.
This article will walk you through using Visual Studio 2010 for the entirety of the Windows Azure application development lifecycle. Note that even if you aren’t a Visual Studio user today, you can still evaluate Windows Azure development for free, using the Windows Azure support in Visual Web Developer 2010 Express.
