Support building NHibernate on .Net 4
.Net 4 has been around for some time. There should be a version of NHibernate built for it.
The main part of this seems to be dropping Iesi.Collection in favor of ISet<T> from the BCL.
This issue is intended to track child issues for specific work items.
It might be interesting if we could build NH4 for both .Net 3.5 and .Net 4, where the former would keep using Iesi.
Retargeting to net-4.0 merged: e9774ebb3300d45400521ae7fefebb5f7770f929
