XRepository (nuget): The XRepository library is an easy-to-configure ORM with a simple API which follows the repository pattern.  It supports automapping, works on mutliple databases, and even supports a JavaScript interface to allow for simple HTML5 application development.  (If you want the JavaScript version, get NuGet package XRepository.JS.  This package will come along for the ride.)  XRepository is a good alternative for those who want powerful ORM capabilities without the difficulty of NHibernate / Entity Framework or the boilerplatedness of Web API.
