ICorProfiler: Why am I getting the wrong type token for the jitted function?

I have some code that is structured like this:

class A {
    void M() {}
}
delegate void B<T1,T2>(T1 key, T2 value);

      

        
        
        
      

    

And I am using the ICorProfiler2 API to profile this code. Now when the M method is jitted, I get the FunctionID * pointer of its ID. Then I do the following (heavily abbreviated):

mdToken functionToken = mdTypeDefNil;
mdTypeDef classToken = mdTypeDefNil;
IMetaDataImport* pMDImport = NULL;
profilerInfo->GetTokenAndMetaDataFromFunction(functionId,
        IID_IMetaDataImport, (IUnknown**) &pMDImport, &functionToken);
pMDImport->GetMethodProps(functionToken, &classToken, functionName,
        sizeof(functionName), 0, &methodAttr, &sigBlob, &sigSize, NULL,
        NULL);

      

        
        
        
      

    

This gives me a TypeToken in a classToken variable.

I The expected is the type in which M was declared in the source (class aka), but instead I get a delegate token of type B. So my question is, am I doing something wrong or my guess is that GetMethodProps does not correctly return the type token of type M ?

Unfortunately the GetMethodProps documentation is not very helpful: https://msdn.microsoft.com/en-us/library/ms233163(v=vs.110).aspx

Edit: To clarify: I know that the wrong type is being returned because I generated a file containing all the type / function markers and the names they map to. I checked these tokens with ILSpy : they are correct. This mapping has also been tested many times in other applications and seems to work very well, so I don't think this is the source of the problem.
