Hey Scott,
Got around to having a proper look at this tonight. Basically, it is down to
the AutoImport stuff the exception mentioned; when NHibernate is given the
first mapping it sees that the entity is named with the full assembly
qualified name and creates an import for the short name (being helpful!),
and then when you add the second one it then complains that this import is
now going to conflict. So the solution is to turn off the auto importing;
unfortunately, we don't have a way to do that in the RC... I've just
commited a fix that adds in the ability to change this in a convention.
So if you get the latest binaries or source, you should be able to
change your Conventions line in your attached project to do this:
.Conventions.Setup(x =>
{
x.AddFromAssemblyOf<Program>();
x.Add(AutoImport.Never());
});
Which
adds all the conventions you've defined in your assembly, then uses
one of the helper conventions to turn off auto importing.
