This week we published a technical whitepaper on Microsoft downloads that discusses in some detail how we enable service virtualization on the .NET platform through the Managed Services Engine (MSE).  Aaron Skonnard of Pluralsight authored this document and does a great job in not only going through specific activities such as versioning a service and defining new policies, but also the application of these activities in virtualizing services through the .NET Service Bus.  This is a very thorough document on the MSE, so if you are looking for a detailed understanding of our approach to service virtualization I strongly suggest you look it over.
