Re: minimizing the cost of managed/unmanaged collaboration

Okay, so I have a tentative plan to convert significant amounts of C++ into managed code,
and to make classes like this one managed:

class MyCplusPlusClass
{
  void DoStuff(IManagedObject managedObject) // native method
  {
    double foo = managedObject->GetFoo("key");
    _bstr_t bar = managedObject->GetBar("key");
    NativeApi(foo, bar);
  }
};

To achieve this I must master compiling my C++ code as managed, and switch from #importing
COM to #using .NET.  This will require exchanging COM smart pointers with __gc pointers.
(Or I could rewrite to C#, but I suppose that's more work.)  Beyond that I don't really know
what it will take.

In the case where static linking is required, I shall split my lib project into a DLL and a
lib, with the DLL being managed and the lib exporting new native methods to call.  The above
class would go in the new DLL. Does anyone foresee troubles along this route?
