COMException from SfPdfViewerControl in designer

When I place the SfPdfViewerControl in the XAML for a Page or UserControl, the designer view (whether in Blend or Visual Studio 2013) reports a COMException, and the designer is unusable.
What can be done so that this exception does not occur, and so I can still design the UI with the PDF control?

COMException: Error HRESULT E_FAIL has been returned from a call to a COM component.
Stack Trace:
   at System.Runtime.InteropServices.WindowsRuntime.IVector`1.InsertAt(UInt32 index, T value)
   at System.Runtime.InteropServices.WindowsRuntime.VectorToListAdapter.InsertAtHelper[T](IVector`1 _this, UInt32 index, T item)
   at System.Runtime.InteropServices.WindowsRuntime.VectorToListAdapter.Insert[T](Int32 index, T item)
