我一直在尝试安装实体框架 6,它总是回滚并出现错误
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
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的所有引用之后我已经是几个了几天后,需要认真的帮助。
我该怎么做才能安装 Entity Framework 6?
注意:它只会安装 find 到类库,而不是 WebApi 或 MVC 应用程序。
如果它有帮助,这里有一些更详细的错误信息。
