You might look CodeFluent Entities but you need to understand that it does not internally rely on any ORM or third party tool.
Entity Framework is an ORM whereas CodeFluent Entities is a full model-first
software factory. It uses a natural and visual modeling approach (like Entity Framework and integrated into Visual Studio) and can generate database scripts, object oriented data layer - code (C#, VB), web services and even UIs components.
