NavigationView: TypeNameParserException is printed in the output when the control is initialized and Windows11 theme is used

TypeNameParserException is printed in the Output pane of Visual Studio, when RadNavigationView is initialized. The exception message is:

MS.Internal.Xaml.Parser.GenericTypeNameParser.TypeNameParserException: 'Prefix 'helpers' does not map to a namespace.'

This happens because of a known issue in the Visual Studio designer, which is discussed here.

This issue can be safely ignored. It won't cause issues in the control at runtime.
