Question

My windows phone app is freezing while loading the main page. I have set breakpoints on the main contructor and it fires the OnNavigatedTo event but never fires the “Loaded” event. It gets through the InitializeComponent() in the contructor. It shows the splash screen and the mainpage application bar, but freezes at that point.

I have recently refactored my main namespace, which was causing the mainpage to not load. I fixed that via the Startup Object.

EVERYTHING was working before the refactoring.

What code should I include? The project is fairly large at this point, so I dont know how much you really want me posting code.

Any ideas??

Ok I found the problem. In App.Xaml.cs I made the following crucial mistake:

Here is my code:

private void CompleteInitializePhoneApplication(object sender, NavigationEventArgs e)
    {
        // Set the root visual to allow the application to render
        if (RootVisual != null && RootVisual != RootFrame)
            RootVisual = RootFrame;

        // Remove this handler since it is no longer needed
        RootFrame.Navigated -= CompleteInitializePhoneApplication;
    }

And here is what is was supposed to be:

    private void CompleteInitializePhoneApplication(object sender, NavigationEventArgs e)
    {
        // Set the root visual to allow the application to render
        if (RootVisual != RootFrame)
            RootVisual = RootFrame;

        // Remove this handler since it is no longer needed
        RootFrame.Navigated -= CompleteInitializePhoneApplication;
    }

Resharper thought it would be best to check if RootVisual was null first. Incredibly irritating mistake as It would just hang at the startup PNG and never load, obviously because RootVisual wasn’t being set.
