[Mono-dev] C++, COM interop

[QbProg]

Hello Mono users and developers!

I have a native C++ class library , a COM wrapper written in ATL and a .NET
wrapper written in C++/CLI.
Now, I'm thinking how it would be possible to write a mono wrapper that runs
mainly in LINUX.
Basically I see two suggested ways:
- Write a flatten "C" version on the library and use P/Invoke
- Use SWIG to do such a thing

I don't like neither of these, since the wrapper has many functions and
classes.
I see a better in using a sort of COM / XPCOM interfaces.

I have no problems in making the wrapper based on interfaces (like I did for
the COM one). The only thing that I can not use are class factories since
COM is not available in Windows. Hoever , I've got no problem in eventually
writing a custom factory for required COM Classes.

I see that there is a main difference between COM and XPCOM interop. (?)
In com you can write
CClass c = new cClass ()

and the COM layer will call the relative class factory. In XPCOm you have to
call manually a function to create the class.

The question is : is there a way to redirect the "new" for a COM class (in
linux) so I can directly call a custom class factory function (this time
"internal") ?
I.e. 
COMClass C = new COMClass;

i.e. instead of calling CoCreateObject should call an internal function
CreateCOMClass ?

I don't know if I made it clear...

I'll continue trying, and I'll share my experience, so maybe users can find
an additional way to wrap C++ classes.

Thank you.
