When you debug your Windows Phone application that use a task and call the Show method your app crash with the following error message:
Navigation is not allowed when the task is not in the foreground. Error: -2147220990
Add Show method in try/catch block
private void appBarButton_Click(object sender, EventArgs e)
WebBrowserTask task = new WebBrowserTask();
task.Uri = new Uri("https://www.myerrorsandmysolutions.com/");
