Does it work if you define the macro BOOST_USE_WINDOWS_H in the project settings?

Yes it does - thanks.

I never used CLR stuff myself, but AFAIK one of the fundamentals is automatic garbage collection (MS refers to this as "managed"). So everything relying on the deterministic behavior of C++ ctors/dtors won't work.

I doubt anything in boost is written with automatic garbage collectors in mind. This article regarding the boehmgc shows how to wrap stl containers - http://www.ddj.com/cpp/184401632

I'm new to this topic as well, so please correct me if I'm wrong so far and with the following statement: there have to be clear interfaces between automatic gc code and normal deterministic code. Mixing doesn't work out of the box.

Best, -- Maik

I am using mixing. I have an unmanaged C++ library which is linked with a managed C++ dll. The unmanaged code does have deterministic destruction behaviour - put a break point in the destructor of an unmanaged class and the break point is reached at the time that is expected. Alice
