private void LcStart_Click(object sender, RoutedEventArgs e)
{
System.Windows.Browser.HtmlPage.Window.Invoke("CallJavaScriptMethod");
}

function CallJavaScriptMethod() {
var streamstart = $.connection.chatHub;
$.connection.hub.start()
.done(function () {
streamstart.server.startstreaming($('#ip').val(),$('#port').val());
});

ServerSide:

public class ChatHub : Hub

Groups.Add(Context.ConnectionId, ip + "," + port);
lcstreamer.setTarget(ip, port);
lcstreamer.StartLcStreaming();
