Project properties -> References error

[Eric]

Hi All,

I got the below error when I clicked on the Project Properties and then
References. Using Visual Studio 2008 64 bits.

Any idea how to fix this problem?

An error occurred trying to load the page.
Unable to cast COM object of type 'System.__ComObject' to interface type
'EnvDTE.ProjectItemsEvents'. This operation failed because the
QueryInterface call on the COM component for the interface with IID
'{22800963-2811-410D-BF87-A7808EAC977D}' failed due to the following error:
No such interface supported (Exception from HRESULT: 0x80004002
(E_NOINTERFACE)).

Thanks,

Eric

Hi Eric,

Do you have any third-party visual studio add-ins or packages installed? Is
the project that you're listing the references for some type of special
project related to this add-in or package? (doesn't have to be to be caused
by the add-in/package)

Either way, this seems to be a bug with an add-in or package, Microsoft's or
otherwise. Try uninstalling that add-in/package or reset your packages.
It's a command-line option, I think, but I don't know it to tell you.

Cheers,

J
