First look at debugging .NET 4.0 dumps in Visual Studio 2010
Tess talks about debugging a memory dump generated in .NET 4.0 using VS2010.
And Wow, VS 2010 supports post mortem debugging for managed application and as Tess mentioned you no longer need to learn WinDbg/SOS for some of the common debugging scenarios. VS2010 also has source server support and along with intutive debugging environment, VS2010 is a big step forward to integrate mixed mode debugging in it.
