Remarks

This method supports markup extension behavior and is not typically called by user code, unless that user code implements XAML processing behavior.

A XAML processor implementation uses this method for proper handling of x:Array elements during object creation. This relies on general behavior for XAML processors when they process any MarkupExtension and call its ProvideValue implementation.

This implementation does not rely on any services based on the passed serviceProvider. However, it does rely on CLR concepts as transmitted by the extension's use while processing with the default XAML schema context for .NET Framework XAML Services.
