body: <p>So, im currently working on a project using C#/XAML for a Windows 8 Store App and I've encountred a problem.</p>
  
  <p>When the user navigates to a Page a ListView with some Controls shows up.
  Then when the user decides to snap the page my application crashes and shows this:</p>

  <p>In my IntelliTrace this shows up and I press an Exception.</p>
  
  <p><img src="https://i.stack.imgur.com/u4L7z.png" alt="enter image description here"></p>
  
  <p>It navigates me to this code.</p>
  
  <pre><code>     /// &lt;summary&gt;
      /// Implement this partial method to configure the service endpoint.
      /// &lt;/summary&gt;
      /// &lt;param name="serviceEndpoint"&gt;The endpoint to configure&lt;/param&gt;
      /// &lt;param name="clientCredentials"&gt;The client credentials&lt;/param&gt;
  
      static partial void ConfigureEndpoint(System.ServiceModel.Description.ServiceEndpoint serviceEndpoint, System.ServiceModel.Description.ClientCredentials clientCredentials);
  
      public EmployeeAssisterClient() : 
              base(EmployeeAssisterClient.GetDefaultBinding(), EmployeeAssisterClient.GetDefaultEndpointAddress()) {
          this.Endpoint.Name = EndpointConfiguration.TimeLoggerEndPoint.ToString();
          ConfigureEndpoint(this.Endpoint, this.ClientCredentials);
      }
  </code></pre>
  
  <p>I add the controls to the listview as follows:</p>
  
  <pre><code>            _timeReports = _timeReportDatabase.GetAll();
  
              foreach (var timeReport in _timeReports)
              {
                  _invoicedControls.Add(new InvoicedControl(timeReport)
                      {
                          Customer = timeReport.CustomerName,
                          Date = timeReport.Date,
                          WorkedTime = timeReport.WorkedTime.ToString(),
                          InvoicedTime = timeReport.InvoicedTime.ToString()
                      });
              }
  
              TimeReportsListViewFillView.ItemsSource = _invoicedControls;
              TimeReportsListViewFullView.ItemsSource = _invoicedControls;
              TimeReportsListViewPortraitView.ItemsSource = _invoicedControls;
              TimeReportsListViewSnappedView.ItemsSource = _invoicedControls;
  </code></pre>
  
  <p>EDIT==============================================================================</p>
  
  <p>This is the error wich is thrown</p>
  
  <p><img src="https://i.stack.imgur.com/964OO.png" alt="enter image description here"></p>
  
  <p>I turned off WCF debugging by typing "C:\Program Files\Microsoft Visual Studio 11.0\Common7\IDE\VsDiag_regwcf.exe -u" into the Cmd and it resolved 2/3 problems</p>
  
  <p>This is the last error in my IntelliTrace:

  <p>What does this error mean? And does any1 have an idea how to fix this?</p>
