----------------------------------

queryover enum support for VB.NET still seems to be missing. Issue [NH-2407] marks the issue closed for the LINQ provider.

Patrick Earl resolved NH-2712.
------------------------------

       Resolution: Fixed
    Fix Version/s:     (was: 3.1.0)
                   3.2.0Beta2

The bug reported here is for the Linq provider and has already been fixed.  If there is another bug for QueryOver, please create another issue and provide a failing test case.
