I just upgraded to VS2010 and am having issues with my development machine. I have a number of MVC sites hosted on my local IIS (Windows 7, 64 bit). Before the installation of VS2010/.NET 4 everything ran fine. Now I'm getting errors of:
HTTP Error 500.0 - Internal Server Error
Calling LoadLibraryEx on ISAPI filter "C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_filter.dll" failed
I have only found one other person with this problem and he had no resolution. Should .NET 4 be trying to load these sites?

Try reregistering with iis from the command prompt. This file located on the windows/Microsoft .NET/

I had the same problem. I also have a 64 bit OS. The event logs informed me that one of the ISAPI filters was failing to load. I am assuming (and I may be wrong) that I had installed the 32bit framework version which my 64 bit OS would not load. Disabling
the .NET4 ISAPI filter & restarting IIS solved the immediate problem.

Thanks a bunch - aspnet_regiis -r worked well
