The second of two articles we wrote for MSDN magazine was published online today (and available in news stands now): http://msdn.microsoft.com/msdnmag/issues/07/03/CLRInsideOut/default.aspx

This article discusses the System AddIn pipeline and we promised to show the utilization of the model to enable compatibility as your Host and Add-In version independently. In this article we’ll first go into detail about the architecture of the model. Then we’ll look at version 2.0 of the application we reviewed last month, using it to get an in-depth view of how our pipeline works, and finally using it to demonstrate how you can use our system to keep add-ins working even as the host changes.
