In a previous post about the AJAX Extensions, I detailed the copy commands to retrieve the DLLs from the GAC. Same thing, this time for the ASP.NET 3.5 Extensions. If you are demoing CTP material in a hosted environment, you will likely need these in your app’s bin to avoid the inevitable configuration error.
copy “C:WINDOWSassemblyGAC_MSILSystem.Web.Extensions22.214.171.124__31bf3856ad364e35″ C:devMMVCAppbin
