Video conferencing in .NET

Question

I add a chat function to one of our software products, I have a chat function and work using WCF. I am going to add video chat functionality again using WCF, basically instead of sending clients messages I will send a video stream. I was wondering if anyone did this with WCF? Is it recommended to do this with WCF?

Also, someone used (and recommends) any components (preferably open source) or libraries for video conferencing in .NET 4. Thanks for any help.

You can use the following approach:

• Use avicap32.dll and COM-interop (or DirectShow.NET) to capture video in webcams.

• Use streaming to send streams over WCF. IIS Live can be used. Smooth streaming:
