This is a bit off topic but since you asked:

Boost can run as unmanaged code under VC++ 7 and 7.1 but can not be called
by managed C++ code. Theoretically managed C++ and unmanaged C++ can coexist
in the same .NET assembly ( shared library ) in what is called "mixed mode",
so that a C++ programmer could use the C++ standard library and Boost among
other things in a .NET assembly, but there is a hideous bug in both VC++ 7
and VC++ 7.1 in which mixed mode assemblies created in C++ can hang up any
process, and there is NO fix for this bug. MS has known about this from the
beta stage of the Visual Studio .NET 2003 product, but has chosen not to fix
it for the life cycle of the .NET products, a period which now stretches
from January 2002 until the present. This effectually destroys the ability
of any C++ programmer attempting to write .NET assemblies using the C++
standard library, and Boost, since the inception of .NET. An amazing story
which has gotten no press at all. Lest you think I am making this up, see .

What an amazing coincidence that this bug means that C++ programmers
currently can only safely write reusable libraries for .NET if they give up
using the C++ standard library and all C++ template programming. Microsoft
says that this bug will be fixed for the next version of .NET to be
tentatively released sometime in 2005.

Managed C++ is different enough from standard C++, that Boost code can not
currently be written in managed C++. There is currently no support for C++
templates in managed C++ code. The next version of managed C++, circa 2005,
has promised support for C++ templates.
