I want to close a window in WPF but it is not close below I am providing you the code sample which I use for closing the window.

public partial class MainWindow : Window


    private WorkflowRuntime wfRuntime = new WorkflowRuntime();

    public MainWindow()



        wfRuntime.WorkflowTerminated += (se, ev) => this.Close(); // this doesn't close the window

        wfRuntime.WorkflowCompleted += (se, ev) => this.Close();


    private void Window_Loaded(object sender, RoutedEventArgs e)


        WorkflowInstance launcherWorkflow = wfRuntime.CreateWorkflow(typeof(InstallerWorkflow));

Probably because the callback is on another thread. A basic workaround is to terminate the application altogether using Environment.Exit(1);

To call the close function on the UI thread you should use:

wfRuntime.WorkflowTerminated += (se, ev) => {

    // call back to the window to do the UI-manipulation

    this.Dispatcher.Invoke(DispatcherPriority.Normal, new Action(delegate()
