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 - https://nhibernate.info - has a range of resources to help you get started, including howtos, blogs and reference documentation.

Latest Release Version

The quickest way to get the latest release of NHibernate is to add it to your project using NuGet (https://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.

Nightly Development Builds

The quickest way to get the latest development build of NHibernate is to add it to your project using NuGet from MyGet feed (https://www.myget.org/gallery/nhibernate).

In order to make life a little bit easier you can register the package source in the NuGet.Config file in the top folder of your project, similar to the following.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="NHibernateDevBuilds" value="https://www.myget.org/F/nhibernate/api/v3/index.json" />
  </packageSources>
</configuration>
