The latest release of ASP.NET MVC had a weird bug: with Visual Studio 2008 SP1, when you open any view page, Visual Studio just vanishes, with no error dialog displayed. The Application log contains an item with the following error message:
.NET Runtime version 2.0.50727.3053 - Fatal Execution Engine Error (6AFD0F92) (0)
With a bit of trial and error, and thanks to some other posts and comments I found out that the reason for this is some conflict with the Visual Studio PowerCommands tool: uninstalling it fixes the problem.
In my previous installation, I found out that uninstalling and reinstalling the TFS Power Tools fixes the problem as well.
