I am trying to launch the SOS.dll from Visual Studio 2010 Ultimate. I get the below errors.

Error during command: IDebugClient asked for unimplemented interface
Error during command: Exception c0000005 occurred at 1BC4EF9E

I have also enabled the unmanaged debugging for the project. Not sure what I am missing.
I tried to launch the sos.dll using following commands

.load sos
.load sos.dll
.load C:\Windows\Microsoft.NET\Framework\v4.0.30319\sos.dll

Not sure what I am missing.

I am able to load SOS.dll when used with VS 2008.
Any advise is really appreciated.

Thanks in advance.

SOS.dll does not work in VS2010 if you have upgraded your CLR to .NET 4.5.
