  Using namespace:  xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

  The InvertedCooleanConverter has the following error:

  Error 710 Ambiguous type reference. A type named 'InvertedBooleanConverter' occurs in at least two namespaces, 'Telerik.Windows.Controls' and 'Telerik.Windows.Controls.Docking'. Consider adjusting the assembly XmlnsDefinition attributes.

  <telerik:RadMenuItem.IsChecked>
      <Binding Path="IsPinned">
          <Binding.Converter> 
              <telerik:InvertedBooleanConverter/>
          </Binding.Converter>
      </Binding>
  </telerik:RadMenuItem.IsChecked>

  How to fix?

  Thanks,
  Kellie

  Hello Kellie,
  
  To workaround the problem you should use the full XML namespace for this converter (the other elements should be OK with the URI namespace):
  
  xmlns:telerikConverter="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls"
  
  <telerik:RadMenuItem.IsChecked> 
       <Binding Path="IsPinned"> 
           <Binding.Converter> 
               <telerikConverter:InvertedBooleanConverter/> 
           </Binding.Converter> 
       </Binding>
  < /telerik:RadMenuItem.IsChecked>

  Are there plans to fix this?  I have an where there is a conflict with this class in code and using Reference aliases (along with the extern alias directives) don't seem to work. The conflict is in Telerik.Windows.Controls and Telerik.Windows.Controls.ScheduleView.
  Thanks,

  Hi Rich,
  
  This issue will be fixed for the upcoming official release. The Converter is already marked obsolete in the ScheduleView assembly. You could test this using one of the latest internal builds.
  
  All the best,

  Thanks for the prompt reply. What I ended up doing to work around that issue was get the source for the latest release and create a new class with a different name. Great to know that I'll be able to remove that after the next release.
  Thanks,
  Rich
