error when hosting WPF control inside of a Winform Application RRS feed

  • Question

  • Hello All,

    I am trying to follow the example for hosting a WPF Control inside of a Windows Forms. While I am doing that it compiles successfully, but I get the error that:

    "NET20andXAML.vshost.exe has encountered a problem and needs to close. We are sorry for the inconvenience."

    Any help on this?


    I am using the WindowsFormIntegration Examples using the

    private void Form1_Load(object sender, EventArgs e)


    // Create the ElementHost control for hosting the

    // WPF UserControl.

    ElementHost host = new ElementHost();

    host.Dock = DockStyle.Fill;

    // Create the WPF UserControl.

    XAML.UserControl1 uc =

    new XAML.UserControl1();

    // Assign the WPF UserControl to the ElementHost control's

    // Child property.

    host.Child = uc;

    // Add the ElementHost control to the form's

    // collection of child controls.

  • Hi Laadlaa,

    I haven't been able to reproduce your issue. Can you supply your machine configuration and the version of the WinSDK you're using?

    I have the following version of SDK:

    Microsoft ® Windows ® SDK Release Notes for September Customer Technology Preview

    Version Sept CTP

    And it does say that it supports

    Important This version of the Windows SDK targets specific versions of Windows and has other restrictions. This version:

    • Is supported on Windows Vista September CTP, which is available from the MSDN Universal Subscribers site on MSDN and from the Beta customer locations.
    • Supports .NET Framework 3.0 September CTP for Windows XP SP2 and Windows Server 2003 SP1, which is available publicly from the Download Center.

  • After glancing it over, your configuration looks reasonable. Did you have earlier verions of the SDK installed before you installed Sept. CTP?

    Also, can you try going the other direction, hosting a WinForms control in WPF? You can use this sample:

    Hosting a Windows Forms Control in Windows Presentation Foundation Sample 

    I'm just wondering if interop is broken in both directions.

  • I think its a problem with the installation, since I had the earlier versions of the SDK and now that I uninstalled it seems there are still some left overs somewhere giving the problem, on the machine with a clean image and new install it works just fine.

    Dont know why though, I am going to see if there is any setting in the registry, if you have any other clue please let me know. I am not sure where are Microsoft people if they are reading this, how come there is no reply.

  • I've had similar problems in the past with old installations. You might want to try this tool:

    Pre-released Microsoft .NET Framework 3.0 Uninstall Tool

    I've had some success with this in the past. Fwiw, I had an issue with the RC1 bits, but when I uninstalled and installed the RTM bits, it went away. Unfortunately, RTM bits aren't publicly available yet, so I hope you have some luck with the uninstall tool.
