MongoDB-CSharp is a library for communicating with MongoDB(http://www.mongodb.org). The Mapper is built on top of MongoDB-CSharp in order to provide static typing to the schema-less document-oriented database.

• POCO entities. - We don't force your entities into anything. While you may have to tweak some things to allow for persistence, those times should be few and far between.
• Automapping - no need to use xml or create classes for mapping; the mapper is able to map your objects to and from mongo without any help. - There is some robust convention support for tweaking if you desire, and almost every option has the ability to be overriden on a class/member basis.
• Linq - Linq is fully supported and, while it isn't complete, will get you most of the way there.
• Change Tracking - This will allow you to pull down an entity and only persist the changes. It allows you to cut down on bandwidth while not sacrificing features.
• Support for inheritance - Inheritance is supported both for collection documents and embedded documents through the use of discriminators.
