I'm getting this error too.
Uninstalling and re-installing Visual Studio 2005 did not work.
Repairing the .NET 2.0 framework did not work.
Has there been a "live update" to the .net 2 framework in the last couple of days?

Fixed it.
You need to uninstall the .NET Framework 2.0 security hot"fix" 922770.

Hi,
I had the same issue after installing VS.Net 2005 SP1 Beta.
I saw in some other newsgroups that if you remove Windows Workflow Foundation VS.Net will work again.
May you check out if you have installed WWF on your System...
For me it helped to remove WWF!
best regards,
Johannes

Thanks Johannes. I got it working after installing WWF and VS components for WWF.
