Integrating C # into a C++ Project

Question

Hello I need to make an application which uses SOAP calls so the best thing to use for this is C # I presume but the rest of the application is written in C++. So we are only going to use the C # for the SOAP calls en methods but still want to use C++ for the rest of the application. Is it possible to call a method from some sort of C++ object inside a C# method? Any help is very welcome. I am completely new to C # .. Thanx Kenzo

Thanx for the reply I will take a look at the C# library exposement to a COM object and see where I can get from there. Normally this should be enough .. Thanx for the help Kenzo

The answer to your question is that it can by done will probably be easy if you're comfortable with COM and may be even easier than that using C++ managed extensions. Because C# is new and the .NET framework is not yet complete such gaps in functionality are filled by interoperating with unmanaged code (like C++). This can be done by exposing .NET DLLS as COM libraries or by calling legacy DLLS or by using COM objects from C#. To call C# code from C++ write a C# assembly (library) and expose it as a COM object. This is just a setting in the IDE. Very easy. To call C++ code from C# put the code in a legacy DLL or COM DLL. Now that I've said all that... Visual C++ 7 has what's called managed extensions. This means that it is a sort of hybrid. It is mainly a Win32 compiler but can access some managed code in some ways. I don't have much information on this and have never used it.
