If there's anyone out there who understands how to do this without hosting the ActiveX control on a Form please post an example.For this article, I will describe the use of DNS Load Balancing. I saw the example they gave and I was unsure hot to use their code for this situation. On a side note I found this question that says there may be a way to use the ActiveX control (for RDP) without using a windows form at all. Private void RdpConnectionOnOnDisconnected(object sender, IMsTscA圎vents_OnDisconnectedEvent e) Var rdpSession = (AxMsRdpClient9NotSafeForScripting)sender Private void RdpConnectionOnOnLoginComplete(object sender, EventArgs e)ĭebug.WriteLine($' # New Session Detected #') Private void RdpConnectionOnOnLogonError(object sender, IMsTscA圎vents_OnLogonErrorEvent e) Task.Delay(500).GetAwaiter().GetResult() RdpClientThread.SetApartmentState(ApartmentState.STA) Var rdpClientThread = new Thread(ProcessTaskThread) RdpConnection.OnLogonError += RdpConnectionOnOnLogonError RdpConnection.OnLoginComplete += RdpConnectionOnOnLoginComplete RdpConnection.OnDisconnected += RdpConnectionOnOnDisconnected Var rdpConnection = new AxMSTSCLib.AxMsRdpClient9NotSafeForScripting() Public void CreateRdpConnection(string server, string user, string domain, string password) When launched from a WinForms or Console app, the a form is shown for a few seconds so I made sure to set the control to enabled = false so it can't be interacted with. The same exact method can be called from a WinForms app or from a Console app. I thought it might not work for creating a session on the local machine but I tested in in 2012R2 running as a Service and it actually can. You'll need to add a COM reference to Microsoft Terminal Services Active Client 1.0 Type Library (ActiveX).

I've created a simple utility that I believe meets all the requirements in the question.
