Not supported by this Dictionary implementation.
Assembly: PresentationFramework (in PresentationFramework.dll)
The ResourceDictionary class does not support registering by name. It uses keys instead. The XAML namescope methods are implemented as inoperative versions in ResourceDictionary to make it clear that XAML names do not apply to resources.
Calling this method will cause a NotSupportedException to be thrown.
Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
