Of course you can, but why? You need to explain your scenario, architecture, and the general ideas.

Use System.IO.Ports.SerialPort,

Hello Sergey Alexandrovich,
I have the same problem right now.
I have idl files (without library block) and I have .c and .h files.
I have also sample app written on c++. It uses NdrClientCall2() to make all calls.
But I write on C# and have to implement (use) these interfaces and types, etc. from idl.

This is not realy clear how can I use idl in c#..

This is an RPC Interface from one mashine vendor and I have to connect to it..

(I speak russian as well)

Thank you for help.
