INameScope::RegisterName Method (String^, Object^)
Registers the provided name into the current XAML namescope.
Assembly: System.Xaml (in System.Xaml.dll)
Duplicate names in a XAML namescope are not permitted.
Notes to Implementers:
Do not permit duplicate names to be registered. If the input name is already assigned to an existing element in the internal collection representation of the XAML namescope (even if it is the same as scopedElement), throw an exception.
Also consider throwing an exception if the provided name does not conform to XamlName Grammar.
