Does anyone know of a fast way to tell through code if a ContentType is one that's a pre-installed one?
Conversely, I want to know if a given ContentType was provisioned by a custom feature / generated by the user through the WebUI.
Sure, there are short ContentTypeIds (like
0x0102) and long ones (
0x0100<flattened guid>), but is there any other way?
I'm asking for any version, 2007 or 2010.
