Entity Developer is a free powerful modeling and code generation tool for ADO.NET Entity Framework, NHibernate, 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. Entity Developer Express for SQL Server is a free limited version of Entity Developer for SQL Server. The Express Edition does not allow customization of code templates and is limited to 10 entities in the project. Entity Developer allows you to create and edit Entity Framework, NHibernate, and LINQ to SQL models visually, without typing a line of XML code. It supports editing storage part in GUI and creating all kinds of mapping, such as table splitting, mapping entity to several tables, complex types, and inheritance hierarchies, creating entities from SELECT statements and methods from SQL code, etc. Code generation is very flexible due to using T4-like templates.
What's new in this version:
Version 5.0.66 has fixed bug with an incorrect element order in the mappings files, when the model has both filter and sql query definitions.
