Isolated shell 2010: Dynamiclly load a Dll before shell startup

Hi All:

I developed a application that base on Visual Studio Shell 2010. Before shell startup, I want to dynamically load the Dll "MsCorEE.dll' to get the hash code for some files. But when running the application, it will popup the following message:

The type name could not be resolved

Parameter name: windowType

When I debugging the code, I found that: If my application calls the funtions "GetHashFromFileW" that from "MsCorEE.dll", the error message will popup. Otherwise, there is no message.

I have make test base on Visual Studio shell 2008. It works OK. 

Did somebody encounter this issue before? or Could anybody give some solution for this issue.

Thanks

Paddy
