Method How to compile C library in .Net dll?

Can we compile the C library as a .net dll (containing and allowing access to all C libs functions) by simply compiling a cpp project containing code like

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

with an argument /clr:purewith VS? (VS10)

Or should we do something more tricks?

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

CLR:PURE just doesn't 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 assebmly and call Bar.Foo.foo()from .NET.

Thus, the basic information that you can compile C ++ in .NET assemblies using the / clr: xxx options is correct, but this does not mean that this is the only thing you need to do to get a useful .NET assembly.
