If you are a .NET and NHibernate user, soon you’ll be able to use Envers in your project!
Simon Duduica has been working on an Envers to .NET port. This is still work in progress, but you can check out the current source code here: https://nhcontrib.svn.sourceforge.net/svnroot/nhcontrib/trunk/sandbox/simondud/Envers.NET
A large portion was ported, but there’s also quite a lot left, so any help is appreciated. Big thanks to Simon and looking forward to a release :)
