Rebuilding the ones do not have a problem but I want to use C# dll additionally. Actually I find C# much easier and that's the reason (and classes from CLR). Roughly it looks like:

#using MyNamespace; // MyNameSpace is in a C# dll

//...
...(..far *parms) 
{
  //...
  MyClass mc = gcnew MyClass(); // a class from DLL
  rettype ret = MyClass( paramarray );
//..
