Hello,

There is no way for the .NET client to use the JS protocol. Why would you want to do that?

The .NET client should use http-streaming but may resort to polling if the streaming connection seem not to be working. The JavaScript client would do the same. See http://www.lightstreamer.com/distros...nListener.html
Are you testing the client against our server or your own? Do you have some kind of proxy in the middle?
