Devart has recently announced the release of Entity Developer 2.80, a diagram-based designer for model creation, runtime simulation, and code generation for ADO.NET Entity Framework and LINQ to SQL.
Entity Developer 2.80 seamlessly integrates with Visual Studio 2008 and Visual Studio 2010 release version. Now LINQ to SQL and Entity Framework models can be edited with Entity Developer inside Visual Studio without any need to open the model in a separate application.
Entity Developer can be used 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. The Method Editor was also greatly improved and now it allows creating multi-result set methods.
