asp.net-mvc - 自更新 NuGet 包以来，VS 一直需要重启

Question

我从模板创建了一个全新的 C# Web 应用程序，并立即更新了它的所有 NuGet 包。

更新过程中需要重启，之后一直提示:

One or more packages could not be completely uninstalled: Newtonsoft.Json.6.0.4. Restart Visual Studio to finish uninstall.

但在重新启动 Visual Studio 后，相同的消息仍然存在。

packages.config 文件包含以下行:<package id="Newtonsoft.Json" version="6.0.4" targetFramework="net452" /> .

Answer 1

尝试在包管理器控制台中手动更新包后，我收到一条错误消息，指出现有文件正在阻止安装。从解决方案包中删除适当的文件夹后，错误消失了，我可以直接从包管理器 UI 更新包。

这是我的控制台打印:
