SHFusion API: retrieving codebase of assemblies in GAC

[Nikander & Margriet Bruggeman]

We're using the "Microsoft.CLRAdmin.Fusion" assembly because we want to
retrieve the exact locations of the assemblies in the GAC. The code looks
like this:

// objAssembly is the Microsoft.CLRAdmin.AssemInfo assembly.
Type objType = objAssembly.GetType();
BindingFlags objBinding = (BindingFlags) 1078;
string strCodeBase = (string) objType.InvokeMember("Codebase", objBinding,
null, objTarget, null);

Now this works fine for most assemblies, although for some assemblies we're
getting an empty code base path, for example for the Office and SharePoint
assemblies located in the GAC. Does anybody know why this happens and how we
can retrieve the exact locations of the assemblies which return empty code
base paths?

Kind regards,
