Is the Real-time Communications (RTC) Client API available in C#
If not, is there a relatively simple way of using RTC API's libraries in a C# application Or, perhaps, the only way to go is to learn C++ ..
The same question - for Windows Peer-To-Peer SDK, and/or any other Instant Messaging technologies, which libraries can be plugged into a custom client application written in C#.
Thank you very much in advance for any hints/links.

However there are many usefull and easy to use classes included that enables you to write servers and clients with ease...
So check out some tutorials on the subject of "remoting"...
Of course there are thir-party libraries. If you don't mind using the MSN protocol you should defenitly google for dotMSN. It is a great pice of code and is really easy to use (you will connect to the network and send/recive messages in minutes).
