How to call RTC Client APIs from C# Code?

Hi,

We need to get some data defined in the Process Configuration Source xml. According to our development environment, all our codes are written in C# and we want to call RTC API such as :projectArea.getProcessData();  in C#. I had called RTC Client API s from Java Code  before ; but I did not make any direct call with RTC client APIs in C# codes.

Is there any way directly using RTC Client APIs in C# or is there the only one way to call RTC Client APIs in C# code is using the OSLC?

Thanks so much for your support,
