Welcome to NHibernate

NHibernate is a mature, open source object-relational mapper for the .NET framework. It is actively developed, fully featured and used in thousands of successful projects.

The NHibernate community website - http://nhibernate.info - has a range of resources to help you get started, including howtos, blogs and reference documentation.

Latest Version

The quickest way to get the latest release of NHibernate is to add it to your project using NuGet (http://nuget.org/List/Packages/NHibernate).

Alternatively binaries are available from SourceForge at http://sourceforge.net/projects/nhibernate.

You are encouraged to review the release notes (releasenotes.txt), particularly when upgrading to a later version. The release notes will generally document any breaking changes.

Community Forums

There are two official NHibernate community forums:

NHibernate Users - a forum for users to find help using NHibernate
NHibernate Development - a forum for the developers of NHibernate

Bug Reports

If you find any bugs, please report them using the GitHub issue tracker. A test-case that demonstrates the issue is usually required. Instructions on providing a test-case can be found here.
