  <p>And errors on the InitializeComponent() line.</p>

          System.Windows.Application.LoadComponent(this, new System.Uri("/App;component/MainPage.xaml", System.UriKind.Relative));
          this.LayoutRoot = ((System.Windows.Controls.Grid)(this.FindName("LayoutRoot")));
          this.SSIDTextBox = ((System.Windows.Controls.TextBox)(this.FindName("SSIDTextBox")));
          this.PasswordTextBox = ((System.Windows.Controls.TextBox)(this.FindName("PasswordTextBox")));

          this.Profiles= ((System.Windows.Controls.ListBox)(this.FindName("Profiles")));
      }
  }
  </code></pre>
  
  <p>I did not get this exception before I converted the WP 7.1 to WP8.</p>
  
  <p>Any help would be appreciated.</p>
  
  <p><strong>Update</strong>:
  I added the entire exception message, does it help pinpoint the issue?</p>
