Microsoft Releases Entity Framework Beta 3

Microsoft released three pairs of entities testing framework December 6 officially announced, the third party database vendors and ado.net 2.0 data provider has agreed to support the framework.

The ado.net entity structure, is the latest Microsoft technologies to support the version of the RTM process. NET 3.5 and Visual Studio 2008.

Entities framework test 3 provides that the data access API. Net 3.5. It framework of the following entities Beta 2, released in August, because it is based on the. NET 3.5 Beta 2.

Addition to support for the final version. Net 3.5 and Visual Studio 2008 beta 3 provides that the new features, bug fixes and significant performance improvements. "We have been faster generation of view, some relatively simple SQL generated, we have taken a lot of feedback from customers in some of these areas," said ELISA flasko, project managers, Programmable data in the Microsoft team. Test 3 also offers more similar to SQL, for example, in some way change certain property code generation incident.

"Changes, and most have been around the mapping and data model entities in the framework of the entity itself," flasko said. "According to the linq implementation [linq to entities], it has been most appropriate and finishing." Users can, but now do a compilation linq questioned better performance.

Luojiedan Jennings, the chief advisers to the oakleaf system is the use of test 3, says this is a major update. "Beta 3:00, which is the formation of the future," he said. "A significant performance improvements - and this is one of the problems, involving almost all doubt is faster, now." Developers has been using Beta 2 should be noted that there is a breakthrough changes in the testing 3. "Most of them are not huge code changes," asserted flasko.

New tools, computer-to-plate test three entities need tools framework of the December 2007 CTP, which was also posted on December 6, and is available for download MSDN. This is the second CTP first preview is released in August.

Die in the latest preview, entity data model designers the ability to store additional procedures to replace dynamic SQL to fill entities. "We already have the ability, and the use of storage at run-time process, SQL Server entities behind the structure, rather than dynamic SQL explained:" flasko. "Now, Die experience will let you die, rather than Code mobile hook the two incidents." Entities framework is built on the ado.net, a connection technology, the technology allows. NET users can proceed to the third party database. The framework provides a conceptual model, the database model so that developers can easily plan on the business logic, according to Microsoft.

Provider ado.net writer 2.0 data providers have promised to support ado.net entity structure, including the core laboratory, Database Technology, IBM, and Sybase, and so on 803806808. These companies are planning to expand their data providers to support framework - three months after it r tms or end of the year.

Oracle is not on that list. "We have been working together with them, but at this point, we are suppliers are included in the press release," flasko said. Microsoft is planning to release ado.net entities framework and asp.net 3.5 expansion, which will include the remaining data services based on the model (codenamed astoria), in the same time frame. All of these technologies are expected to be in the first half of 2008, but the actual production has not been finalized. "We have not locked, ship vehicles for asp.net 3.5 expansion," flasko explained.

The upcoming launch of the asp.net 3.5 CTP to the expansion of this month is expected to provide the first public preview of the model - View - Controller (M VC) option, support for rest, the A JAX additional functions, and dynamic data control. Data Control, which included a scaffolding structure, will provide an open source. NET tool kits, subsonic.
