a document oriented provider for Sql-Server & SqlCe4
SisoDb is a document-oriented db-provider for Sql-Server written in C#. It lets you store object graphs of POCOs without having to configure any mappings. Each entity is treated as an aggregate root and will get separate tables created on the fly.
