ADO.NET团队在AtMix07会议上宣布启动两个孵化项目：Jasper和Astoria。Jasper基于ADO.NET实体框架，允许开发者仅通过连接字符串即可开始应用程序核心的编程工作，而无需自行构建数据层。Astoria旨在使应用程序能够作为数据服务暴露数据，通过HTTP访问，并使用URI标识信息资源。

At Mix 07 , ADO.NET Team has introduced two incubation project , Jasper and Astoria .

"Jasper"

Jasper is build on the ADO.NET Entity Framework,enables developers to start withmerely a connection string and immediately begin programming the core of application without buildingtheir own data layer ,writing queries andbinddata to UI

“Jasper” uses a set of new technologies to make this happen:

Dynamic generation of data classes so there is no configuration or design time code-gen to carry around.
Rich query and O/R capabilities because “Jasper” is built on top of the Entity Framework.
Auto-binding capabilities for ASP.NET, WinForms, and WPF to make binding data to a UI simple and automatic

"Astoria"

"The goal of Microsoft Codename "Astoria" is to enable applications to expose data as a data service that can be consumed by web clients within a corporate network and across the internet. The data service is reachable over HTTP, and URIs are used to identify the various pieces of information available through the service. Interactions with the data service happens in terms of HTTP verbs such as GET, POST, PUT and DELETE, and the data exchanged in those interactions is represented in simple formats such as XML and JSON.
