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.
File an issue about it at the project site on GitHub. Oh, and you are of course most welcome to fix it and send in a patch or pull request.
