Inbäddad MySQL Server C# Wrapper?

jag känner inte till något .NET-omslag för det här biblioteket även om jag minns att det talades om att införa stöd för det här biblioteket i .NET Connector från version 5. Jag kan dock inte hitta någon information om det just nu.

Det finns några exempelkoder där ute på webben som du kan utöka din kod på. Jag antar att den mest kompletta skulle vara http://forums.mysql.com/ read.php?38,67281,67917 ->
