I am trying to debug my silverlight application running under IE8.0. Its using .NET framework 4.0 and Silverlight 4.0. So I attach Windbg to IE running instance, I understand that with IE8 I need to connect to right instance of internet explorer. So when I attach here are the dlls that been shown as loaded in the process. As you can see the coreclr is loaded in there.

Problem is that after loading sos when I try to load sos, I get following error.
0:027> .loadby sos coreclr
0:027> !threads
Failed to find runtime DLL (clr.dll), 0x80004005
Extension commands need clr.dll in order to have something to do.
Any idea what I am doing wrong here?
