The System.ComponentModel.ExtenderProvidedPropertyAttribute is injected automatically by the System.ComponentModel.TypeDescriptor class on properties that are exposed as extended properties.
Do not use this attribute on your properties. Instead, use the System.ComponentModel.ProvidePropertyAttribute on a type that implements the System.ComponentModel.IExtenderProvider interface. For more information, see Extender Providers.
