Object

The object value to set on the property where the extension is applied.

Exceptions

The AssemblyName property is null. You must set this value during construction or before using the ProvideValue(IServiceProvider) method.

Remarks

This method supports WPF XAML processor implementation, and is not intended to be called directly. The XAML processor implementation uses this method for proper handling of ThemeResourceDictionary extension values during object creation.

This implementation relies on services based on the passed serviceProvider. It must not be null. The serviceProvider object is expected to implement IXamlTypeResolver.
