A way How to Compile C library into .Net dll?

Can we compile C library as .Net dll (containing and opening access to all C libs functions) by just compiling cpp project containing code like

extern "C" {
#include <library.h>
}


with
/clr:pure
argument with VS? (VS10)

Or we should do something more trickey?

Answer

I found it is the best to use the old style Managed C++ for this.

CLR:PURE just wont cut it.

Example:

extern "C" int _foo(int bar)
{
  return bar;
}

namespace Bar
{
  public __gc class Foo
  {
  public:
    Foo() {}

    static int foo(int bar)
    {
      return _foo(bar);
    }
  };
};

Compile with: /clr:oldSyntax

Now you can reference the assebmly, and call Bar.Foo.foo() from .NET.
