I am trying to connect to server, but in the following lines,
LSClient c = new LSClient();
c.OpenConnection(connInfo, new RzConnectionListener() );

I got the exception, error as:

An unhandled exception of type 'Lightstreamer.DotNet.Client.PushUserException' occurred in DotNetClient_N2.dll

Additional information: Requested Adapter Set not available

RzConnectionListener is my class from IConnectionListener, as the following.

public class RzConnectionListener : IConnectionListener
private long bytes = 0;

public RzConnectionListener() {}

public void OnConnectionEstablished() {
Console.WriteLine("connection established");

public void OnSessionStarted(bool isPolling) {
if (isPolling) {
Console.WriteLine("smart polling session started");
} else {
Console.WriteLine("streaming session started");


Can you please help?
