The ClearCanvas developer community will be pleased to know that the inaugural version of the ClearCanvas SDK is now finally available!  We've invested a great deal of time trying to make it as easy to use as possible.  It comes complete with Visual Studio templates & wizards, a comprehensive Developer's Guide and a full API Reference.  And if that isn't quite enough for you, we also have a number of discussion forums to help you with your development related questions.  So try it out and let us know what you think!
