'calling_convention' : can only be used on native member functions

A calling convention was used on a function that was either a global function or on a managed member function. The calling convention can only be used on a native (not managed) member function.

For more information, see Calling Conventions.

The following sample generates C3865:

// C3865.cpp
// compile with: /clr
// processor: x86
void __thiscall Func(){}   // C3865

// OK
struct MyType {
   void __thiscall Func(){}
};
