Add solution to vault:

Unable to cast COM object of type 'System.__ComObject' to interface type 'Microsoft.VisualStudio.Shell.Interop.IVsHierarchy'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{59B2D1D0-5DB0-4F9F-9609-13F0168516D6}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

The first thing to try is to reregister some of dlls that Visual Studio sometimes forgets about:

Code: Select all

regsvr32 actxprxy.dll

Uninstalling and reinstalling the Vault Client will probably fix the problem as well.

Un-installed and re-installed the client.. seems to work now.
