Microsoft has released a new community technology preview of the ADO.NET Entity Framework. This CTP contains updates to the ADO.NET Entity Framework since the Visual Studio Codename "Orcas" Beta 1 release, including changes in Object Services, Query, Entity Client, and the Entity Data Model Wizard in Visual Studio.

Microsoft is still far from finishing this software, however. This is suggested by the fact that the preview targets one single version of Visual Studio, this being Visual Web Developer Express. You cannot use the CTP with other version of Visual Studio for now. Is nice though, to be able play with future versions of pre-released software, and know in advance how the database programming will change using Microsoft development tools.

The Entity Framework has had a bumpy existence from the start. Microsoft first intended to release is as part of Visual Studio 2008 "Orcas", which is set for release later this year. But in late April the Redmond giant sacked it out from VS2008, saying it will be offered later next as an extension to VS2008.

You can download the CTP here.

Update: You can find installation instructions on the ADO.NET team blog
