atlcom.h:3448: Error: C2259: 'ATL::CComContainedObject<contained>'

Question

Due to an updated library I have to migrate a large c++ program from VS2010 to VS2015. In VS2010 all compiled OK. The compiler of VS2015 now shows an error in Microsofts own atlcom.h

I have no chance to abandon the ATL stuff as my DLL is an extension to a major progam which relies on ATL (and is compiled in VS2015…).

This is the error message of cl 2015:

The error points to line 3448 of atlcom.h (compiler of VS2015):

CComContainedObject<contained> m_contained;

The definition of CComContainedObject is Line 3277 of atlcom.h:

template <class Base> //Base must be derived from CComObjectRoot
class CComContainedObject : public Base
{
public:
    typedef Base _BaseClass;
    CComContainedObject(_In_opt_ void* pv) 
    {
        m_pOuterUnknown = (IUnknown*)pv;
    }
    // some additional members
}

My class is:

Any ideas? You are really welcome.
