Entity Developer is a powerful ORM modeling and code generation tool for NHibernate, ADO.NET Entity Framework, LinqConnect, and LINQ to SQL. You can use Model-First and Database-First approaches to design your model and generate C# or Visual Basic .NET code for it. It introduces new approaches for designing ORM models, boosts productivity, and facilitates the development of database applications. Entity Developer seamlessly integrates with Visual Studio 2008, 2010, and 2012. You may edit your Entity Developer models as Visual Studio documents, in the same way as EDM models.
