Visual Studio 2015 中右键单击 Web 项目中的文件夹时上下文菜单变慢
Slow context menu in Visual Studio 2015 on right click folder in web project
我们的一些团队在 Windows 10 Pro 64 位上试用 VS 2015 时遇到了这个问题：
Visual Studio 2013 context menus slow only in web application project
右键单击文件夹（仅在 Web 应用程序项目中的文件夹）时，呈现上下文菜单和任何对话框都会出现长时间延迟。

Disabling Resharper

运行 右键单击期间的进程监视器显示在 CreateFile/ QueryNetworkOpenInformationFile/CloseFile 序列中处理的每个项目引用 4 次，如下所示：
知道这里发生了什么吗？延迟太长而无法忽略，并且发生在右键单击和上下文菜单中的每个选择中。
我们向 Microsoft 提交支持请求后，发现问题是 Web 应用程序项目中的项目引用损坏
删除引用后，上下文菜单正常运行，没有任何滞后。
我刚刚用不同的方式解决了这个问题。
只需删除以下内容：
