A wrapper for a C++ class Blah:

EDIT:

ref class BlahWrapper {
  BlahWrapper () {
     blah = new Blah();
  }

  !BlahWrapper() { //Destructor called by GC
     if (blah != null) {
         delete blah;
         blah = null;
     }
  }

  ~BlahWrapper() { //Dispose() called in "using" blocks,  or manually dispose
     if (blah != null) {
         delete blah;
         blah = null;
     }
  }

  private:
  Blah* blah;
}
