Remarks

The behavior of this method differs depending on the purpose of the IServiceProvider instance. When this object is providing a service provider, it delegates to the GetServiceImpl method. When this object is wrapping an unmanaged service provider, it gets the GUID of the type and delegates to the GetService method.
