Remarks

Only applies when the managed signature of a method takes an object.

int MyMethod(Object o); //Managed signature  
    HRESULT MyMethod(VARIANT o); //COM signature  
    MyObject o = new MyObject();  
    MyMethod(o); //o gets passed as VARIANT VT_DISPATCH  
    MyMethod(new UnknownWrapper(o)); //o gets passed as VARIANT VT_UNKNOWN
