Visual Studio 2015中的慢速上下文菜单，位于Web项目中的右键单击文件夹中

Question

我们的一些在Windows 10 Pro 64位上试用VS 2015的团队正在看到这个问题：

Visual Studio 2013 context menus slow only in web application project

右键单击文件夹（仅限Web应用程序项目中的文件夹）时，渲染上下文菜单以及任何对话框都会有很长的延迟。

我们尝试过以下方法：

Restarting Visual Studio, and re-opening the solution
Cleaning the solution, and deleting the obj folders.
Recreating the project
Clearing Resharper's Cache
Disabling rich client / hardware graphics acceleration in Options->Environment->General
Disabling Resharper
Deleting all Temporary ASP.Net folders
Deleting the contents of %localappdata%\Microsoft\WebsiteCache
Deleting all *.suo user options files
Uninstalling all extensions (Web compiler, Bundler and Minifier)
Probably some other things that I have forgotten.

右键单击期间运行进程监视器会在CreateFile / QueryNetworkOpenInformationFile / CloseFile序列中显示正在处理的每个项目引用4次，如下所示：

这里有什么想法吗？延迟太长而无法忽略，并且右键单击和上下文菜单中的每个选项都会发生。

Answer 1

在我们向Microsoft提交支持请求后，事实证明该问题是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，没有任何延迟。

Answer 2

我刚以不同的方式解决了这个问题。

只需删除以下内容： C：\ Users \ 用户名 \ AppData \ Local \ Microsoft \ WebSiteCache
