How maintainable is the code in the Enterprise Library?

Since first seeing the Code Metrics feature in the Development Edition of Visual Studio Team System 2008, I’ve been on a quest for bad (read: unmanageable) code. Rather than face the tool towards my code, I thought I would pick on Microsoft.

… and it looks like the EntLib has a maintainability index between 77 and 89.

Thanks to Ajoy krishnamoorthy for actually doing the hard work on this.
