Visual Studio 2013 context menus slow only in web application project - visual-studio-2013

Question

I recently upgraded from VS 2010 to VS 2013 for a new project. I'm finding that when right-clicking on a folder (but not an individual file) in my Web Application project, it takes about 2 seconds for the context-menu to load. The other dozen or so non-web projects in the solution do not have this performance problem. Additionally, within that slow context menu, if I click on the Add-> item to bring up the sub-menu to add a new view/class/whatever, that menu takes anywhere from 5-10 seconds appear. If from there I think choose something like "New Scaffolding Item", that dialog can take about 30 seconds to appear.
Others on my project do not seem to be having this issue, though they've got slightly better hardware and are running Windows 8 (vs me running Windows 7). I've tried disabling the visual experience elements as described here but it did not seem to have an effect. My system only seems to be using about 5GB of the 8GB available RAM, and my CPU Usage never goes above 30%. I've tried disabling ReSharper in case that was somehow causing the slowdown, but it had no effect on performance.
How can I fix this huge slowdown?

Update: In a hope to fix this, I completely wiped my hard drive and updated to Windows 8. I also upgraded to 16GB of RAM. I then installed just enough software so that I could compile the project. I'm still getting the same slowdown. However, if I create a brand new Web Application, the context menus are speedy. Could something about the project itself cause a slowdown?

Answer 1

I am having the same issue as you. Old web projects are effecting and new web projects are ok.
What I found is I am using a lot of NuGet package in the project and local NuGet cache (C:\Users\xxx\AppData\Local\NuGet\Cache) is empty because this is new machine.
I recompile the whole solution. NuGet packages are caching in that folder. After compilation is successfully, problem solved.
I am not sure what is happening but this solve my problem. Strange thing is I need to recompile all solutions. Uncompiled solutions have this issue and after compile, this is gone.

Answer 2

We were struggling with the same issue from a long time. Right Click on a project or on the any folder inside project used to take at least 10 seconds for the menu to appear. The solution was quite simple.
Just get rid of all the broken references.
Please refer following image. Such broken references need to be removed.
Remove such references and try right click again, context menu will appear withing a fraction of seconds.
This worked for us.

Answer 3

If its happening for a single project means, you can try out the following
Delete .suo file in your project.
And then Restart the visual studio.
Try loading your project again.
This may provide you a fine solution.

Answer 4

Just to add to the possible solutions, I had the same problem.
BTW I am using VC-2013 Ultimate with R# and NCrunch.
Right clicking on any solution item took forever. I closed the solution and deleted the _ResharperXXX folder in the solution directory.
The problem was gone after I started the solution again.
This has happened a few times now and I have managed to fix it by doing the above every time.
