Finally I upgrade my development machine with Vista RC2 (build 5744), but after this I lost WPF designer (Orcas RTM). In event log I see following errors (most related):
One or more Visual Studio templates do not match any installed project packages.
.NET Runtime version 2.0.50727.308 - Fatal Execution Engine Error (7A2B852A) (0)

Any advice?
Thank you
