Devart has recently announced the release of dotConnect products for Oracle, MySQL, PostgreSQL, and SQLite -- ADO.NET providers that offer Entity Framework support, LINQ to SQL support, and contain an ORM model designer for developing LINQ to SQL and EF models based on different database engines.
New dotConnect ADO.NET providers offer complete support for Visual Studio 2010 and Entity Framework 4 release version.
Entity Developer 2.80, a designer for modeling and code generation for ADO.NET Entity Framework and LINQ to SQL, included in Professional Edition of every dotConnect, has been greatly improved. Now Entity Developer seamlessly integrates with Visual Studio 2008 and Visual Studio 2010 release version. Entity Developer LINQ to SQL and Entity Framework models can be edited inside Visual Studio without any need to open the model in a separate Entity Developer application. You can use Entity Developer for creating models for both Entity Framework 1 and Entity Framework 4 release version. For example, such feature as Lazy Loading is now supported for Entity Framework 4 release version models.
