I have a legacy COM component which I need wrap and use in .NET code. When I used the tlbimp to create the RCW for the component just one interface had a coclass created to which I was able to make a call. Rest five or so interface does not have a coclass. If I look up in ildasm on the interop there are just interfaces without coclass.
How do I make this work to be able to call all methods on the component. Is there a way I can add coclass code myself in and expect the implementation to work.
