Visual Studio 2010中的EntityConfiguration和ContextBuilder在哪里？ [英] Where is EntityConfiguration and ContextBuilder in Visual Studio 2010?

问题描述

我看到例子

I see examples about code-only POCO for en entity framework 4, but I cannot find the classes EntityConfiguration and ContextBuilder and I cannot see which reference I need to add to have them.

它是.NET Framework 4的一部分，还是我们必须下载其他东西？

Is it part of the .Net Framework 4 or do we have to download something else?

推荐答案

您正在寻找的POCO内容for是在一个单独的下载。当前版本位于 http：/ /www.microsoft.com/downloads/details.aspx?FamilyID=af18e652-9ea7-478b-8b41-8424b94e3f58&displayLang=en

The POCO stuff you're looking for is in a separate download. Current version is at http://www.microsoft.com/downloads/details.aspx?FamilyID=af18e652-9ea7-478b-8b41-8424b94e3f58&displayLang=en

一旦你运行安装程序，您将需要获取Microsoft.Data.Entity.CTP.dll文件（我的C：\Program Files\Microsoft ADO.NET实体框架功能CTP3\Binaries目录）。对新的dll进行项目引用，你应该设置！

Once you run the installer, you'll need to grab the Microsoft.Data.Entity.CTP.dll file (mine was in the C:\Program Files\Microsoft ADO.NET Entity Framework Feature CTP3\Binaries directory). Make a project reference to the new dll and you should be set!
