Try deleting it out of the project references, and out of packages.config. Then re-add it.
尝试将其从项目引用中删除，并从packages.config. 然后重新添加它。

- Try it without -Force.
- Try to specify -ProjectName parameter and execute it over each project that includes the EntityFramework package.
- 不用 -Force 试试。
- 尝试指定 -ProjectName 参数并在包含 EntityFramework 包的每个项目上执行它。

I experienced a similar issue, and it came down to an incorrect path. You are unable to find the package as the full namespace for Entity Framework is Microsoft.AspNet.Identity.EntityFramework.
我遇到了类似的问题，归结为不正确的路径。您无法找到包，因为实体框架的完整命名空间是 Microsoft.AspNet.Identity.EntityFramework。
Therefore, to uninstall you need to enter the following into the Package Manager:
因此，要卸载，您需要在包管理器中输入以下内容：
Uninstall-Package Microsoft.AspNet.Identity.EntityFramework
Uninstall-Package Microsoft.AspNet.Identity.EntityFramework

I have been facing this issue for days. To solve the issue I tried the latest version of framework, uninstalled it and installed previous version. All the possibilities tried were not working for me. At last, I found a solution and just run the below command at Package manger Console.
我已经面临这个问题好几天了。为了解决这个问题，我尝试了最新版本的框架，将其卸载并安装了以前的版本。尝试的所有可能性都不适合我。最后，我找到了一个解决方案，只需在包管理器控制台运行以下命令即可。
PM>install-Package Microsoft.AspNet.Identity.EntityFramework
everything is done by itself. Uninstalling old version and installing the latest version of Ef under Microsoft.AspNet.Identity.EntityFramework 2.2.2and it updates the files of my project by itself.
一切都是自己完成的。卸载旧版本并安装最新版本的 EfMicrosoft.AspNet.Identity.EntityFramework 2.2.2并自行更新我的项目文件。
