C# Open remote application locked within Windows form

We're developing a C# Windows application, and one of the things we want to do with it is open a remote application inside our program. We can open a connection to the application's server using MSTSCLib, but to open our remote application either we open a remote desktop connection and open the program (which we don't want to do) or we open the remote application but in a separate window (which also isn't ideal).

This is how we get the remote application to open in a new window; is there a way to open the remote application inside the RDP client?

private AxMSTSCLib.AxMsRdpClient9NotSafeForScripting rdp;
rdp.RemoteProgram2.RemoteProgramMode = true;
rdp.OnConnected += (_1, _2) =>
{
rdp.RemoteProgram2.ServerStartProgram(@"C:\Windows\System32\calc.exe", "", "%SYSTEMROOT%", true, "", false);
};
rdp.Server = "servername.com";
rdp.UserName = "domain\\user";
rdp.AdvancedSettings7.PublicMode = false;
rdp.AdvancedSettings7.ClearTextPassword = "password";
rdp.Connect();
