PInvike or Interop resources?

[Pat O]

I am writting/maintaining a native library that will be used by .Net
code as well. This is not a COM library. Is there a good source of
information on how PInvoke works with native libraries? I have been
trying things to figure out how they work. I am also wondering if
there is a way to run the native debugger when the starting executable
is a .Net app?

Well, do you mean by "how PInvoke works" what actually happens as far as how
the DLL is loaded, when it's loaded, etc. or just how to declare the calls
in your library for managed code to use?

No, there's currently no way to step from the managed debugger into native
code with the Compact Framework.

"How it works" is really broad. There are lots of online resources for
everything from basic P/Invoke handling to the more esoteric and complex.
If you have a more specific question we may be able to help.

One that comes to mind (becasue I wrote it) is this one:

There is no way to debug stepping across the boundary from the managed to
native debugger. I typically debug one end then the other or use two
instances of Studio, process attachment and DebugBreak calls.
