Let's say you've written a great client (that is, not web) application. Perhaps you've added some specific features to make it great on Windows 7. Certainly you've made sure it runs on Windows 7. Or perhaps on Windows Server 2008 R2. Or maybe your app runs on Windows Azure, or Windows Phone 7. Good work! You put time and effort into confirming that your app fits your chosen platform. Now, would you like to be able to prove it with a suite of automated tests and a logo that shows you passed them? Of course you would.
So head on over to Microsoft Platform Ready
and take a look around. You'll find training resources to help you build applications that target Windows 7, Windows Server 2008 R2, and Windows Azure. You can test your app and get logos like Powered by Windows Azure
and Works with Windows Server 2008 R2
.You can even showcase your application in a marketplace, and take advantage of special offers like extended trials of developer tools from various partners.
This is an obvious step for anyone building a client application, on any part of the Microsoft platform. Investigate, join, reap the rewards
