EntityDataSource和Entity Framework 6

本文介绍了EntityDataSource和Entity Framework 6的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我正在学习ASP.NET。我来到了EntityDataSorce控件。我使用的是EF6。我读过这个控件和EF6有一些问题，冲突，但是最后更新到EntityDataSource这个问题已经解决了。 blogs.msdn/b/webdev/archive/2014/02/28/announcing-the-release-of-dynamic-data-provider-and -entitydatasource-control-for-entity-framework-6.aspx

我试图跟随上述链接。首先我创建一个.edmx模型

使用NuGet安装新的EntityDataSource Contro

我添加了两个EntityDataSource控件，并将其中一个更改为ef的前缀。所以我有两个控件其中一个是旧的，另一个是新的更新

当我点击旧的，我可以看到配置弹出窗口并进入配置数据源屏幕。但是当点击新的时候，没有弹出窗口。那么如何配置数据源？ 这是什么问题？

解决方案

使用EF6时不支持用户界面。我们不再建议对新项目使用实体数据源，所以我们只是为EF6提供了可用的数据源。您需要在标记中直接执行配置。

I am learning ASP.NET. I came to EntityDataSorce control. I am using EF6. I have read that this control and EF6 have some issues, conflicts, but with the last update to EntityDataSource this issue has solved. blogs.msdn/b/webdev/archive/2014/02/28/announcing-the-release-of-dynamic-data-provider-and-entitydatasource-control-for-entity-framework-6.aspx

I am trying to follow above link. First I create an .edmx model

Install new EntityDataSource Contro with NuGet

I added two EntityDataSource controls and changed prefix of one of them to ef. So I have two control one of them is old and other one is new updated

When I click the old one I can see the configuration popup and reach the Configure Data Source screen. But when click on the new one there is no popup. So, how can I configure data source? What is wrong with this?

解决方案

The user interface isn't supported when using EF6. We no longer recommend using the Entity Data Source for new projects, so we just did the work to provide a data source that is usable with EF6. You need to perform configuration directly in the markup.
