Looking for code sample on creating C++ DLL then P/Invoke in C# (For Windows CE 5/6)

I am experienced in C# but not in C++. Recently my Windows CE 5 C# program is hitting performance issue and I am considering moving calculation to C++ DLL then P/Invoke it from C# since C++ supports hardware float-point co-processor while .NET CF does not.

I am searching the net all morning trying to find a complete sample that demonstrate creatin开发者_开发百科g C++ DLL then P/Invoke in C# but could not find any.

Could anyone point some good sample or article for me?

Thanks a lot!!

Take a look at the first answer of this question. This deals with declaring your C functions so that C# can P/Invoke them.

A very useful page when P/Invoking is pinvoke.net, check it out

I finally found a good article discussing how to create C++ DLL for C#
