But this is what I need for this project...

The UUIDs are said to be optimized for fast indexing and are smaller,
so that this is the choice for the DB. The GUIDs, however, are the
standardized representation and have to be used on the application
level. I don't know enough about uuidlib's UUIDs to convert them to
GUIDs in the application.

Maybe. But at least I know how to program in C# :-)
