The first of two articles we wrote for MSDN magazine was published online today (and available in newstands now): http://msdn.microsoft.com/msdnmag/issues/07/02/CLRInsideOut/default.aspx

 This article introduces you to our APIs and walks through a sample application hosting add-ins. Next month we'll focus on V2 of the same application and go through the details of our architecture and how it solves the versioning problems.
