      Entity Framework 4.1 - Update 1 is now available, please install Update 1 instead of this release.

      ADO.NET Entity Framework 4.1 introduces two new features:
      • The DbContext API is a simplified abstraction over ObjectContext and a number of other types that were included in previous releases of the ADO.NET Entity Framework. The DbContext API surface is optimized for common tasks and coding patterns.
      • Code First is a new development pattern for the ADO.NET Entity Framework and provides an alternative to the existing Database First and Model First patterns. Code First is focused around defining your model using C#/Visual Basic .NET classes, these classes can then be mapped to an existing database or be used to generate a database schema. Additional configuration can be supplied using Data Annotations or via a fluent API.
  • Supported Operating System
