c# - RemoteApp 会话在单独的窗口中打开，而不是在 WPF 用户控件中打开

Question

我正在编写一个 WPF UserControl，它使用 AxMSTSCLib 库托管 RemoteApp 会话。我正在使用来自这个 SO question的信息。我写的代码非常接近那个问题的答案。

我将 RemoteApp ActiveX (axMsRdpClient9NotSafeForScripting1) 放在我的 WPF UserControl 中，并在连接时提供必要的参数。

但问题是包含 UserControl 的 WPF 窗口打开但为空白。RemoteApp 实际启动但在主 WPF 窗口之外的单独窗口中。如何确保远程应用程序在 WPF UserControl 中打开？我错过了什么？

这是我的代码：

public void Connect()
    {
        try
        {
            axMsRdpClient9NotSafeForScripting1.UserName = @"domain\username";
            axMsRdpClient9NotSafeForScripting1.Domain = "GTCS";
            axMsRdpClient9NotSafeForScripting1.AdvancedSettings7.ClearTextPassword = "password";
            axMsRdpClient9NotSafeForScripting1.AdvancedSettings9.AuthenticationLevel = 2;
            axMsRdpClient9NotSafeForScripting1.AdvancedSettings9.EnableCredSspSupport = true;
            axMsRdpClient9NotSafeForScripting1.AdvancedSettings9.NegotiateSecurityLayer = false;
            axMsRdpClient9NotSafeForScripting1.AdvancedSettings9.RDPPort = 3389;
            axMsRdpClient9NotSafeForScripting1.Server = "GT-DZ1-ATLS.GTCS.LOCAL"; // 10.24.141.199
            axMsRdpClient9NotSafeForScripting1.RemoteProgram2.RemoteProgramMode = true;

            axMsRdpClient9NotSafeForScripting1.OnConnected += (o, e) =>
            {
                m_connectionState = axMsRdpClient9NotSafeForScripting1.Connected;
                ((ITSRemoteProgram)((IMsRdpClient9)axMsRdpClient9NotSafeForScripting1.GetOcx()).RemoteProgram).ServerStartProgram(@"||startchrome", "", "", true, "", false);
                //axMsRdpClient9NotSafeForScripting1.RemoteProgram.ServerStartProgram(@"||startchrome", "", "", true, "", false);
            };

            axMsRdpClient9NotSafeForScripting1.AdvancedSettings7.PublicMode = false;
            axMsRdpClient9NotSafeForScripting1.DesktopWidth = SystemInformation.VirtualScreen.Width;
            axMsRdpClient9NotSafeForScripting1.DesktopHeight = SystemInformation.VirtualScreen.Height;
            axMsRdpClient9NotSafeForScripting1.AdvancedSettings9.SmartSizing = true;
            IMsTscNonScriptable secured = (IMsTscNonScriptable)axMsRdpClient9NotSafeForScripting1.GetOcx();
            secured.ClearTextPassword = "password";
            axMsRdpClient9NotSafeForScripting1.AdvancedSettings7.ClearTextPassword = "password";

            axMsRdpClient9NotSafeForScripting1.AdvancedSettings9.RedirectClipboard = true;
            axMsRdpClient9NotSafeForScripting1.AdvancedSettings9.RedirectPrinters = true;
            axMsRdpClient9NotSafeForScripting1.AdvancedSettings9.RedirectPorts = false;
            axMsRdpClient9NotSafeForScripting1.AdvancedSettings9.RedirectSmartCards = true;
            axMsRdpClient9NotSafeForScripting1.AdvancedSettings9.RedirectDrives = true;
axMsRdpClient9NotSafeForScripting1.Visible = true;
            axMsRdpClient9NotSafeForScripting1.Enabled = true;
            axMsRdpClient9NotSafeForScripting1.Connect();
            m_connectionState = axMsRdpClient9NotSafeForScripting1.Connected;
        }
        catch (Exception ex)
        {
            var err = ex.Message;
            MessageBox.Show(ex.Message);
        }
