    Create a .NET interface to C++ classes

    Hello

    I have written all code for a client server application in C++. It is
    standard C++ written using Visual Studio v6. Basically C++ and STL.

    I want to provide a .NET interface for those developers who use vb.net, C#,
    etc.

    Can anyone give me some pointers as to how to get started. Do I need to
    purchase the .NET Visual Studio? How much .NET will I need to learn? Any
    resources on how to write a .NET wrapper around C++ classes?

    Angus

    p.s. If there are more appropriate newsgroups please let me know.

      There are several possible solutions:

      AFAIK you can use the free Visual C++ Express edition, but I couldn't
      figure out if this compiler supports C++/CLI (the C++ .NET extensions),
      otherwise you would have to purchase the edition supporting it.
      By the way the name Visual C++ .NET is somewhat misleading, since it's
      still a native C++ compiler, with some .NET extensions.

      You should at least have some basic knowledge about .NET. Memory
      handling, .NET framework and the basic data structures / lists. etc.
      Additionally you should have a good knowledge about C++/CLI - a standard
      ized extension for C++ to access / provide access for .NET.

      I would suggest you to start with C# (free express edition available)
      and play around with the .NET framework, to get familiar with the
      framework and garbage collection. You have to use C# anyways to check
      your C++/CLI wrappers.

      After that you should get familiar with C++/CLI, which you will use to
      wrap your native C++ classes.
      You may have a look at STL/CLR (the .NET compatible implementation of
      the STL) too.

      Hope this helps to start.

          In addition to the other reply:

          If you don't want to use an IDE/compiler that supports C++/CLI (like VS2005
          or VS2008), and you want to continue using VC6, you may build a COM wrapper
          to your existing C++ code.

          VC6 supports COM development, using both ATL and MFC (I don't know about
          your code details, but I would suggest using ATL to make a thin COM wrapper
          on your existing C++ code).

          VB.NET and C# can use COM objects.
