Visual Studio 2013 Update 2 maxes out core

Question

I recently installed Visual Studio 2013 Professional Update 2 on a Windows 7 virtual machine. I had been running VS 2012 with no problems, but I wanted to upgrade. Everythin

Answer 1

My CPU load was 15-25% on a core i7 and went down to 0% after deleting the .sdf files in my project folders.

Answer 2

For what it's worth, I had similar issue with Server Compact 4 being missing, and my c++ solutions being at 25% cpu usage all the time. I had Server Compact 4 SP1 installed though. My system is Windows 7 64 bit. I uninstalled SP1 and downloaded and installed Server Compact 4 and now everything is ok. I have of course got Intellisense back as well.

Answer 3

From what I can tell from Googling Microsoft.VisualStudio.JavaScript.Web.Extensions.dll, that DLL is related to the Web Essentials plugin. If you disable that plugin in particular (failing that, all plugins), does the problem go away?

If it is a problem with a plugin, either live with it being disabled or contact the developer.

Answer 4

All I've found thus far is a workaround: unload and reload the startup project of my solution in the Solution Explorer after opening the project. This will return the cpu usage down to normal (~0% idle).

Answer 5

I know you said you have no extensions, but you might want to double-check on this one. It looks like the Web Essentials extension is incompatible with VS 2013 Update 2 and may cause the described behavior. The workaround is to download the latest nightly build of Web Essentials. You'll have to do it by hand as the one last stable release on Nuget is several months old, before this fix.

Answer 6

I just had this issue; for me it was resolved by installing Update 5.

The issue started occurring after installing the latest MS Updates; a full list of which are given below (NB: my date format is UK: DD/MM/YYYY; today is 10/12/2015 - some fixes listed were (will be?) allegedly installed on the 11th):

Earlier (before using Visual Studio / noticing the issue) I'd uninstalled another hotfix relating to Outlook, which had caused it to open in Safe Mode.
