Some of our team who are trialing VS 2015 on Windows 10 Pro 64 bit are seeing this issue:
Visual Studio 2013 context menus slow only in web application project
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.

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

A context menu is a pop-up menu that provides shortcuts for actions the software developer anticipates the user might want to take. In a Windows environment, the context menu is accessed with a right mouse click.
Many people have CCleaner and might have overlooked the Context Menu editor that's built-in. Click on Tools > Startup and click on the Context Menu tab. Right-click any entry, and you can disable or delete it. You can also save to a text file or open in Regedit or the folder that it resides in.
A. Pressing Shift-F10 will bring up the context menu for any selected item. Just pressing F10 shifts the cursor focus to the first menu item (normally File).
After we submitted a support request to Microsoft, it turns out the issue was a broken project reference in the Web application project
After removing the reference, the context menus behave normally, without any lag.

I have just solved this problem in a different way.
Simply delete the contents of: C:\Users\ username \AppData\Local\Microsoft\WebSiteCache
