Implements

IVsLanguageContextProvider::UpdateLanguageContext(UInt32, IVsTextLines^, array<TextSpan>^, Object^)

The given object can be queried for the IVsUserContext interface by casting it to the IVsUserContext interface: IVsUserContext pContext = ptr as IVsUserContext.

The base method calls the other LanguageService::UpdateLanguageContext and always returns S_OK.
