System.Windows.Application.OnLoadCompleted never reached

Hello I am trying to handle the Application.LoadCompleted event but it's never triggered.

Instead I am seeing the MainWindow.

I tried attaching the event by either xaml, or directly by overriding the OnLoadCompleted method of the Application class.

It's possible you're using the wrong event for what you want.

If you are just trying to initialize your application - perhaps to set up global messaging handlers or you can use OnStartup.

public partial class App : Application
{
    static App()
    {
        DispatcherHelper.Initialize();
    }

    protected override void OnStartup(StartupEventArgs e)
    {
        InitializeMVVM();
    }
}

It could be simply that you're attaching the event too late. i.e. after the loaded event has already fired. Show us the code...

Does your MainWindow contain a Frame?

If you read the text for the event (not the On... method), it says

Occurs when content that was navigated to by a navigator in the application has been loaded

I just tested on a Form with a Frame and the event fires just fine.
