[SUPPORT REQUEST] Using RpcLibrary for testing against a native client.

[ericvergnaud]

Hi,

just starting to look at RpcLibrary.
Thanks for the great work.

We have an app developed in C++ that comprises a client and a server talking to each other over Win32 RPC using "ncalrpc".
In order to automate testing, I'm looking at mocking the server using RpcLibrary.

I'm able to create the server and have it listen, but when the client connects, it complains that the interfaces differ (error 1717 RPC_S_UNKNOWN_IF).

This is not surprising since on the server side, although I'm using the proper GUID when starting the RpcServerApi, I haven't specified any interface yet.

I haven't found examples where the interface is specified. What am I missing ?

More broadly, is my goal achievable i.e. is it possible to have a native Win32 RPC client talk to an RpcLibrary server ?

Worth mentioning, the client is using code generated from an idl.
The failing API call is NdrClientCall3.

@csharptest any advice ?
