Key Features

Wide database support
LinqConnect supports SQL Server, SQL Server Compact, Oracle, MySQL, PostgreSQL, SQLite;
Compatibility
LinqConnect uses classes and interfaces completely compatible with LINQ to SQL, while extending its functionality, so LINQ to SQL developer can easily get started to work with LinqConnect;
Fluent mapping support
Unlike attribute mapping, fluent mapping does not modify entity classes, allowing them not to be persistence-aware. Application code performs mapping, so mapping is always checked for errors during compilation. Mapping can be easily modified at run-time;

Professional development team
LinqConnect is developed by a company having more than eight-year experience on the development of the data access technologies in .NET;
