Primary Objects publishes Linquify v1.6 on CodePlex. Linquify is a C# .NET business class generator for LINQ to SQL and the Entity Framework, helping to support rapid development of .NET and ASP .NET web application data layers. Linquify is free for use under the LGPL.
Linquify installs as a Visual Studio 2008/2010 addin, which allows you to select your LINQ to SQL dbml file or Entity Framework edmx file and automatically generate a set of easy to use business classes. The generated classes allow you to support a complete 3-tier software architecture and simple handling of database objects, with full support for LINQ queries. Customizations to the generated classes can be easily made within the generated user partial classes.
Linquify is free to use, under the LGPL v2.1, giving sufficiently flexible permissions to allow the use in both open source and commercial projects.
