Notes to Inheritors

Override this method to provide your own conversion. Use the culture parameter to specify the language and culture. Use the context parameter to extract additional information about the environment from which this converter is invoked. This parameter can be null; therefore, always check it. Also, properties on the context object can return a null reference (Nothing).
