Building a DLL written in C for use in a C# program

1
my system: 1.7 GHz CPU, 3/4 GB RAM
My tools: MS Visual Studio 2002, MS Visual Studio 8 (C# express edition), Framework .NET 2.0 SDK

I am trying to write a dll to include my existing C program into a C# program I am writing. Somewhere I heard that I need C++ to accomplish this but the documentation on how to do this seems incomplete. I am quite new to both C# and C++. I saw something about PlatformInvoke, but can't find any detailed how-to's. Suggestions for good documentation?
For example, how will my C language dll signal to the C# parent that it has finished doing the requested calculation?
Thanks,
bdt

Read your C# doc topics on interoperability.

I am moving this thread to the .NET forum.
