[SOLVED] My app close when navigate to another page on windows phone 8.1

My app close when navigate to another page on windows phone 8.1

I'm using MVVM Light Toolkit to build an app in windows phone 8.1, When I use Navigation Service's NavigateTo method my app close without throwing an error. This issue seems to be randomly.

I'm using the typical MVVM architecture. I Use a ViewModelLocator in which I use unity to register all my dependencies.

Solution

Here is the (shorted) code of the NavigateTo method implementation:

public virtual void NavigateTo(string pageKey, bool persist = true)
{
    if (!_pagesByKey.ContainsKey(pageKey))
        throw new ArgumentException(string.Format("No such page: {0}. Did you forget to call NavigationService.Configure?", pageKey), "pageKey");
    ((Frame)Window.Current.Content).Navigate(_pagesByKey[pageKey]);
}

So this method can only crash if you forgot to configure the page you are trying to navigate to, or if the Navigate method of the WP frame fails.
