How to intercept API calls from .net app when using IAT patching?

How to intercept API calls from .net app when using IAT patching?

I can intercept the API from a c++ application, but I'm having trouble with .net applications.  With C++ apps, I just get the module handle of the .exe and I can get the correct IMAGE_IMPORT_DESCRIPTOR for the specific dll using ImageDirectoryEntryToData().  But with .net, when I use the .exe as the module handle(as handle parameter for ImageDirectoryEntryToData()), I get mscoree.dll and the api functions I want to intercept are not in that dll.  Anyone know which module to look into?  I'm guessing that one of them calls GetProcAddress whenever an API is called.
