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 [英] Slow context menu in Visual Studio 2015 on right click folder in web project

问题描述

我们的一些团队在Windows 10 Pro 64位上试用VS 2015会遇到这个问题：

Some of our team who are trialing VS 2015 on Windows 10 Pro 64 bit are seeing this issue:

Visual Studio 2013上下文菜单仅在Web应用程序项目中缓慢

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。

When right-clicking a folder (only a folder in a web app project) there is a lengthy delay in rendering the context menu, as well as any dialogs.

我们尝试了以下方法：

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显示在CreateFile / QueryNetworkOpenInformationFile / CloseFile序列中处理的每个项目引用4次，如下：

Running process monitor during a right click shows every project reference being processed in a CreateFile/ QueryNetworkOpenInformationFile/CloseFile sequence 4 times, like this:

任何想法这里发生了什么？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择都会发生。

Any ideas what is happening here ? The delay is too long to ignore and occurs for the right click and every selection from the context menu.

推荐答案

在我们向Microsoft提交支持请求后，事实证明问题是Web应用程序项目中的项目引用已损坏

After we submitted a support request to Microsoft, it turns out the issue was a broken project reference in the Web application project

删除引用后，上下文菜单表现正常，没有任何延迟。

After removing the reference, the context menus behave normally, without any lag.
