I had hoped that this book would contain a fuller description of how to call native code DLLs from C# using the P/Invoke mechanism (with "DllImport").

Currently I am trying to pass an array of PointFs back and forth between a native code DLL. I had to post queries on the MSDN forum to get an answer. The Help on this is fragmented.

Is there another Wrox book that describes how to do this in detail? I have "Visual Studio 2010" Wrox book and it doesn't go into this at all.
