In this article written by Kathleen Dollard for the Visual Studio Magazine you will learn how to work through debugging challenges posed by stable composition in MEF Preview 7, and get insight into
using MEF with Silverlight.
Stable composition was introduced in MEF Preview 7, and it also appears in beta 2 of .NET 4. For more on MEF and stable composition, see the Ask Kathleen columns "Getting Current on MEF" (October 2009) and "Working with MEF" (April 2009). Stable composition offers stability that keeps applications that are relying on MEF from failing when bugs or deployment errors make a plug-in unusable. However, it also creates significant debugging problems.
