I have visual studio 2015 enterprise edition, update 1.
When idle, the visual studio process is using around 10-15% cpu constantly.
I tried the solutions provided here with no success.
The solution includes 11 c# projects.
The issue seems to appear only after the first compilation after the solution.
In my case a few *.mdb files had been added to the solution which triggered a constant cpu usage of 30-35%.
So generally the content of a solution triggers background tasks which can lead to high cpu usage. If that usage occurs suddenly, it's worth to get maybe an older source version to check, if the problem is related to added files.
In my scenario the visual studio process remained active using cpu even after closing visual studio. Using process explorer I identified two threads using the cpu indicating following start addresses:
clr.dll!CreateApplicationContext
devenv.exe!IsAssertEtwEnabled
After a lot of attempts and tests to fix this issue, I finally discovered the source of it.
I had a Code Map dgml file in the solution.
Removing the file fixed the issue, and now the devenv process cpu consumption returned to normal.
UPDATE:
After some time working, it seems that just removing the Code Map dgml didn't entirely solve the problem. The solution at last was to remove the reference to the "Modeling Project" containing it(along with other documents such as Sequence Diagrams...).
My project is in visual studio 2010 and now I want it to migrate to 2012. when I open my project in 2012 I am able to build the solution. but when I am running it.
It starts use RAM more than 8 GB and system get hanged not able to open even task manager.
please help me what should I do to work my project in visual studio 2012.
My code in vb.net.
PS : using IIS
thanks in advace !!
This doesn't seem like a problem of VS at all, the problem probably originates in your code somewhere, which could be caused by the upgrading mechanism. Without your code we can't really get a hang of what is going one. Although, you said the memory usage is maxing itself, this being said I'd advice you to download dotMemory. It'll help you find memory leaks and other related memory issues. It has a 5 day trial so if I were you I'd definitely check it out.
I'm currently evaluating Visual Studio 2015 RC. I've noticed when running the IDE, The Visual Studio 2015 process is constantly at around 25% CPU usage. Even without a project loaded and without the welcome page it is gobbling up 25% CPU usage at a constant rate. No other applications running other than background services. All other running processes use around an additional 2 to 4 percent CPU overall.
This behavior has also been noticed in Visual Studio 2013.
Is anyone else seeing this behavior? Is this normal? Any suggestions?
Had this same problem. Processor constantly at 45-50% even when the IDE is completely idle.
Turns out the problem is the Microsoft Git Source Code provider.
I turned that off and processor dropped to 0 and the IDE became much more usable.
In my case disabling Telerik ASP.NET MVC Extension solved high CPU issue.
High CPU load started on solution load and didn't drop (40% with one, 80% with two solutions) until VS was closed or even sometimes after (had to kill the process).
Tools->Extensions and Updates->Installed, find the extension and click 'Disable'.
In my case all reference counts tried to update every time when I edit code.
I have just turned them off. You can do it this way.
It’s not to be expected that Visual Studio should chew up continuous CPU time.
I am running Visual Studio 2015 Community RTM right now with a medium sized project open, and am not seeing any ongoing CPU usage (according to Process Hacker 2, which shows usage as small as 0.01 percent). It’s just blank, which means not even 0.01% CPU usage is registering.
Keep in mind that IntelliSense scans your project files in the background to build the database for popping up its suggestions, etc.
Choosing Project > Rescan Solution from the menus will result in that process being done over, which will cause the CPU to be used for a time. But it should ultimately go quiet.
Seemingly forever, there have been times when deleting the Intellisense Database files and doing a full rescan solves “odd behavior” type problems. I don’t know if it’s the “prescribed” method, but if I suspect an IntelliSense problem I just delete the .sdf file in the project folder if I want to make sure Visual Studio starts with a clean slate. This isn’t necessary very often.
I also had this problem, constant 20-40% CPU when idling (Visual Studio 2015 update 1). I noticed that other local repositories of the same code did not have this problem.
I deleted the problematic local repository and took a new checkout, this solved the issue for me. Why this worked, I unfortunately cannot explain...
I run resharper, turned that off and turned off the Microsoft Git provider and still had high CPU issues, devenv.exe would also run after close... until recently.
It appears VS 2015 Update 2 has resolved these issues!

In my case; "Visual Studio 2015 Update 1" gone crazy editing JS files regarless of the length of the source. It used high CPU and the editor is even freezed. I fixed the issue by disabling the 3rd party add-ons by one-by-to detect the buggy one causing VS 2015 malfunctioning.
Hope it works.
In my case, the culprit was Node.js tools for Visual Studio. I had v1.1.2 installed and the cpu was constantly around 25-40%.
A switch to Node.js Tools v1.2 RC resolved the problem completely after an initial high load that went away in a couple of minutes.
In my case it was either the Roaming Extention Manager or most probably the azure worker role project in my solution. If you have one of these try unloading it and restart visual studio. I can reproduce it but I don't know why it happens.
I've noticed also that when running and stopping a debug episode on the local server, if the page is still open in the browser, VS will continue to run at high CPU. Closing the browser page stops this.
I want to share my experience,
In my case I had to diable all extensions and updates and code analysis c#.
1-For extensions and updates :
Tools => Extensions and updates
2-For the code analysis
Solution explorer => right click on the project => Properties =>Click on the tab "Code analysis" => click on the "Open" bouton => Uncheck the checkbox "Microsoft.CodeAnalysis.CSharp" => save and exit.
Cpu usage descended to 1 %.
In my case, The .suo file in Visual Studio was the culprit. Deleting it fixed my issue.
Refer below link for more details.

I am using Visual Studio Ultimate where came to know my all hard disk space is reducing day by day. Then got into a folder Program Data\Visual Studio\10\TraceDebugging Where it used almost 116 Gb of my space. I dont know how to get rid of it and kinda skeptical removing manually. If anybody has faced this before or know the safest way to turn off or remove this files. Please help me with that.
Thanks in Advance.
Everything I'm finding on the internet seems to say that these files are perfectly safe to delete. There was a bug in Visual Studio 2010 that was not cleaning up these files. A later service pack fixed the cleanup code.
You should install Visual Studio 2010 Service Pack 1 to correct the issue in the future. The files are safe to delete manually.

I'm working on a solution in Visual Studio (v10.0.30319.1) which contains 8 C# projects (WPF Application and Class Libraries). I've been working on this solution for several months, but yesterday I started having problems with Visual Studio hanging for some time when starting and stopping my app in the debug environment.
I first notice it when I stop the application and VS hangs for around 5 seconds. I then press F5 to start again and it takes 5-10 seconds to start. Then I stop the application and it takes about 10 seconds to stop. The problem subsequently worsens until I reboot the computer (I'm not sure if restarting VS is sufficient - I will test and update the question when it happens again).
Once the computer has been restarted, I cannot replicate the problem, but I know it will creep up on me again today.
While the problem is happening, one of the cores is at 100% usage. Memory usage for devenv.exe is normal at a bit over 200MB, and not increasing.
The computer is quite powerful and everything else is working correctly so I'm sure it's not a resource issue.
Did you update VS2010 with Service Pack 1?
Microsoft Visual Studio 2010 Service Pack 1 Download
Be warned, although the page says it's only an 800 KB download, what is actually downloaded is a downloader that downloads over 800 MB of patches. (That's a lot of "downloads" :P)
Delete your solution user option files i.e. {SolutionName}.suo and {SolutionName}.docstates.suo
It worked for me, before doing that I tried #Casey solution but it didn't work.
so first try deleting files, if it do not work then update VS2010 and then delete files again.
