问题描述

我一直在尝试安装实体框架6，它总是回滚并出现错误

I keep trying to install the entity framework 6 and it always rolls back with the error of

error: This operation would create an incorrectly structured document.

我已经卸载了对该位置提到的每个 dll 的所有引用.http://entityframework.codeplex.com/wikipage?title=Updating%20Applications%20to%20use%20EF6

I've uninstalled all the references to every dll mentioned at this location. http://entityframework.codeplex.com/wikipage?title=Updating%20Applications%20to%20use%20EF6

疯狂的是，我可以创建一个新项目，创建一个 webAPI 程序，并尝试添加 Entity Framework 6，但我得到了同样的错误，即使在删除了对 System.Data.Entity.dll 的所有引用之后也是如此 我已经了解了几天，需要认真的帮助.

The crazy thing is that i can create a new project, create a webAPI program, and attempt to add Entity Framework 6 and I get the same error, even after removing all references to System.Data.Entity.dll I'm already a few days into this, and needing serious help.

如何安装 Entity Framework 6?

what can i do to get Entity Framework 6 to install?

注意:它只会安装 find 到类库，而不是 WebApi 或 MVC 应用程序.

Note: It will install just find to a class library just not a WebApi or MVC application.

如果有帮助，这里有一些更详细的错误信息.

If it helps here is some more detailed error info.
