I am using the 2010 version of Visual Studio, but am having many problems with delays - my computer has a good configuration of RAM, and processor - especially when saving files.
Currently I am carrying a medium-sized project, only one open file (ASP.NET page) using a single suite of components from third party, the Telerik. And yet, in time to save, or modify the tab, the entire IDE is slow. I know there may be several factors for this problem, but I'm not carrying the computer (the problem apparently is the memory management on behalf of the IDE).
Does anyone know any way to improve it? Change settings, Windows services. Oh yes, I'm using a plugin to modify the color of the IDE and another to find (Ctrl-click) the object reference.
Memory Initialization:
Memory: 280000K
Virtual Memory: 350000K
Have you tried disabling all the plugins and make sure that it is VS that actually causes the slowdown?
I have Resharper installed and VS can be slow sometimes. I turned it off (suspend on v5), and VS is back to blazing speed. Of course, inversely coding productivity is impaired by not having Resharper.
There are many causes and circumstances that can lead to what you're describing. So I'd better recommend you to check the links bellow...

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!
https://www.visualstudio.com/en-us/news/vs2015-update2-vs.aspx
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.

I'm experiencing some performance problems. When I edit a file, Visual Studio 2008 performs a background (on-the-fly) compilation and then, it updates the error list. During this time, the cursor in the file editor disappears, and the keys I press to move or type more character are buffered.
Once the background compilation is finished, the changes are reflected in the editor (1 - 2 seconds). Every time I edit a file, which happens often, this happens.
How can I fix this problem? If this is not possible, can I disable this automatic build?
I had an odd performance-related issue today. My Microsoft Visual Studio seemed to be taking far too long to perform even the simplest of operations. I Googled around and tried a few ideas that people had such as disabling add-ins or clearing Visual Studio’s recent projects list but those suggestions didn’t seem to solve the problem. I remembered that the Windows SysInternals website had a tool called Process Monitor that would sniff registry and file accesses by any running program.
It seemed to me that Visual Studio was up to something and Process Monitor should help me figure out what it was. I downloaded the most recent version, and after fiddling around a bit with its display filters, ran it and to my horror, I saw that Visual Studio was so slow because it was accessing the more than 10,000 folders in C:\Users\krintoul\AppData\Local\Microsoft\WebSiteCache on most IDE operations. I’m not sure why there were that many folders and moreover, wasn’t sure what Visual Studio was doing with them, but after I zipped those folders up and moved them somewhere else, Visual Studio’s performance improved tremendously.
The Windows SysInternals website has a number of other useful utilities for network management, security, system information and more. Check it out. I’m sure you’ll find something of value.
I come from a strong Java background and in recent years have been also developing in C#.
What I can never understand is how far behind (Personal Opinion) the Visual Studio IDE's are in compared with Intelli-J IDEA and Eclipse (Java).
There have been improvements by Microsoft from VS 2005 to VS 2008, but I feel they are not quite there in terms of taking the development experience to the next level.
What I want to know is, is VS 2010 any different?
Why is it that the tools and syntax editors are so much more "evolved" in the Java IDE's.
Just to name a few:
Code Completion (Much more advance in Java IDE's)
Ant Integration (Eclipse and IDEA) vs Visual Studio Build Events
Lack of Code Repository integration in VS (Subversion and CVS) out of the box.
Lack of Advance Re-factoring Tools in Visual Studio.
Thanks.
A few points…
People tend to like what they know.
It is quicker to get up-to-speed in C# as the IDE and most of the tools / docs come from a single source.
In the Java world you have a lot more chooses, this is great for expert that spend times learning about them all, but does also lead to its own problems.
Adding ReSharper or Refactor to Visual Studio may give you what you want.
The Visual Studio debugging is great.
Visual Studio tries to make life easy for you by trying to find missing dlls etc and then storing where they are in the registry. This may be great for a 1 man project, but can often lead to build problems across developer’s machines if you are not careful. In the Java world you have to edit more config file by hand, but at least you can put these files under source code control.
There is not a small command line tool that works well on a build server that will build all types of Visual Studio projects. However in day to day usage you don’t need to learn how to use command tools, as Visual Studio hides them form you.
I think these days most programmers
are just happier with the IDE they
know best.
Note I wrote this over 6 years ago, since then C#/.Net has got a lot more complex, with lots of open source projects. Microsoft has also open sourced a lot of the .net framework. For web and server side development I expect there is now little to choose between the Java world and the .Net world. For “smart clients” .net still have a lot to offer including the new support from cross device phone development.
For multi-threaded IO, I think c# is years ahead of Java, but that could change as C# and Java keeps learning from each other...
Visual Studio has definitely been coming on over the last few years - although many of the improvements have basically been things that Eclipse has had for ages (I haven't used IDEA myself).
You may well want to look at ReSharper, which brings more goodness to Visual Studio, along with the VS2010 Productivity PowerTools.
Also, have a look at Scott Guthrie's blog series about improvements in VS2010. Lots of goodies in there.
All tools have their strengths and weaknesses - these days I'm about as happy in Visual Studio as in Eclipse... although I'm much happier writing C# than Java :) One area where Visual Studio really shines is debugging though... I find things like the VS Watch window to be much better than Eclipse's equivalent.
Visual studio 2017 is still far far behind Intellij IDEA. I'm using both and i can say that even VS2017 with ReSharper is not comparable with IDEA.
Biggest problem for me is that VS still doesn't offer usable hot reload debugging experience. I'm crying every time i have to rebuild my .NET MVC project (it is +- fast, but IIS Express load time ~ 15s EVERY time you make even the smallest change in your code).
If you want to argue with "Edit and continue" so so hotreload function - it is absolutely useless, you can't do almost any change in code without rebuilding (and everytime you have to manually break code and close opened tab with useless information).
So i'm really looking forward for full version of IntelliJ Rider bringing all super user friendly possibilities of IntelliJ IDEA to the .NET world!
I don't agree with you. I think VS is much more easy to use.
For example, when i need to create a web application. I open VS and create a new project (Web Application). After the project created, i press f5 and tadda!...
But if want to create my web application with Java, i need to install a server or some frameworks. Still i don't know how can i create a web application?
Or, Windows Application.
At VS, you don't need do any thing to create a windows based application like web application. but if i want to create windows based application with Java, i had to do something.
I think VS IDE is more user friendly than Java IDE's.
Is it safe to use the beta versions of Visual Studio?
By safe I mean, while developing any project in this studio, is it probable that it may cause some losses to my project? Or any other kind of risk?
Should I just use the studio 2008 and
wait for the stable version of Studio
2010?
Purpose of the question: I am doing my graduation project in .NET framework (includes - C#, WPF etc.).So I don't want to put my project at any risk because of some issue regarding (beta) visual studio.Hence the question.
As long as you are using a version control system, there should be no problem. Simply check out your project (or better yet, create a vs2010 branch) to an experimental folder and work from there.
There are no hidden risks when you use version control appropriately.
Visual Studio 2010 will convert your project files to its new format, meaning you'll have trouble if you want to go back to VS2008 later. I'd suggest holding off for now unless you can find a way to keep both old and new versions of the project files up to date.
There's always a risk in using beta software (but then again, there's always a risk in using any software). The whole reason it's called beta is because the company is not confident that it's got all the bugs worked out. Otherwise, it would have been released so they could start raking in the moola.
There are quite a few ways to mitigate the possibility of any beta software (not limited to VS2010 or even any programming-related product) from causing you trouble. Choose any from this list, which is by no means exhaustive:
Don't use it on the same data (be it accounting information or source code) until you've run it in parallel and gotten the same results as with the older version.
Plan a backout strategy if the software is so bad that it's easier to go back than to try and go forward.
Backup your data even more frequently during the periods where you're using the beta software, up until the point that you're comfortable with it and can revert to a more normal backup strategy.
Don't use beta software at all - wait for the real release (or SP1 if you want to be even safer). There may not be a driving force behind updating to the latest version.
As a company, limit your exposure to the beta software to a small set of your employees. So, for example, if you have six different teams, choose the least important as a sacrificial lamb, so to speak.
My own personal preference is to wait until everyone else has sorted out the problems first. I didn't upgrade to the latest Ubuntu while it was in beta (I still got burnt a little bit with the video and X but that particular problem already had a solution on the net). I don't download the latest and greatest Eclipse until it's been in use for a few months. I'm still using VS2008 under Windows XP since there's nothing I think I need in the latest release (of VS or Windows).
We obviously have the latest and greatest OS' in our test environments but they're crash-and-burn environments that won't cause any real pain if they blow up (other than a rebuild but even that's pretty painless nowadays).
For your particular circumstance, I would probably stick with a tried and true version. You don't seem to have a pressing need for any of the new features in your question and the sort of failure you're talking about is not just losing some information at work which, while annoying, is probably backed up to the point where your career would survive.
A similar loss of your educational work would affect you for a long time if you fail your subject because of it. I would probably just concentrate on getting it finished rather than worrying about what VS2010 beta might do to my work. Don't misunderstand me, you should still be protecting your work even with VS2008 but I'd personally feel safer with that option.
Then, if you have some spare time at the end of your project (hah! as if that would happen!), you could try to convert what you've done so far to VS2010. If it all goes pear-shaped, you still have all the VS2008 stuff available.
There is certainly risk in using unproven software in that it could behave unexpectedly. Some of the answers here focus on protecting your source code and that is a valid concern, but you should also consider other risks.
Could Visual Studio 2010 make your system unstable? Having your source code in a local instance of source control won't do you much good if Visual Studio corrupts your hard drive. Even if you backed up regularly, you'd still be out a good day or two (MINIMUM) rebuilding your desktop.
Also, what do you intend to do with the finished product? Will a professor attempt to open the project on their own desktop? Are you expected to deploy it to another environment? We see these "Works on my computer" problems using proven software, a beta certainly increases the probability of running into this type of problem.
So yes, there is certainly increased risk in using a beta. You can take steps to mitigate the risks but with important work those are steps you should be taking anyway. Is the benefit of using Visual Studio 2010 worth the increased probability of delays / data loss / grade impact?
I know I'm experimenting with VS2010 and I haven't seen severe problems but betas are not proven/guaranteed - the overall risk is probably slight but it is a risk nonetheless.
I guess I would approach the question differently...Is there any real value in using VS 2010 over 2008? I have been using both for a while and I would say, No.
I have had some mysterious crashes with VS 2010 and the application has disappeared on me, causing me to lose any unsaved data.
If you are integrating IronPython / Ruby or working with Office or VB style COM, there is more support for this in .NET 4.0. Beyond that, most of the changes add some shine to the IDE, but not much real value.
my 2 cents.
The biggest risks you will face are crashes, random tool window misplacements, and occasionally Visual Studio will refuse to start and you will have to reset all your settings to have it working again. 1 (I am anyway reasonably happy with Visual Studio 2010 and don't regret having installed it; in my case the compelling reasons were unit testing and visual designer for Silverlight)
But as ocdecio says, there should not be danger for your code, especially if you use a source control system.
As an additional advise, target your projects to .NET Framework 3.5. Using a beta development tool may be ok, using a beta .NET Framework in a production environment is usually not.
1 This crash is supposed to be caused by using raster fonts for the code editor, but it has happened to me without using this type of fonts.
Given that you've said the project will be "tested on another system", the answer is simple: use VS2008. VS2010 solutions cannot be opened by earlier versions, and I wouldn't bet my graduation project on whether or not someone else has VS2010 installed.
Other reasons to stick with VS2008:
VS2010 probably doesn't gain you much.
There are bugs, and I'd rather be working on getting my graduation project done rather than working around problems with my development tool.
If you need help along the way, those that can potentially help probably aren't using the same version. That may make a difference, it may not.
Another thing to consider.. usually the EULA prohibits you from deploying and/or shipping a product using a Beta version of the toolset. I'm not sure this applies in your situation but it's a point to consider.
Another potential issue I've heard of is that sometimes Visual Studio betas refuse to uninstall when it comes time to put in the RTM version. So as long as you don't mind reinstalling Windows when you're ready to install RTM and you've taken the other answers into consideration, then go ahead.
Since your project is for a graduation project and not for full production release, I would say use the latest/stable version of Visual Studio 2010.
You will gain more than you will lose as you will be using the latest technology which will be more useful going forward.
There is an issue for touch screen machines which may render WPF applications unusable.
A workaround exists. See details:
‘MS.Win32.Penimc.UnsafeNativeMethods’ Threw An Exception
fix: C:\Windows\Microsoft.NET\Framework\v3.0\WPF>regsvr32 PenIMC.dll
The biggest problem I have with VS2010 Beta 2 is designer. The Windows Form Designer generates buggy code (Microsoft Connect bug id 507267 and 499925). So I have to edit the form in older version of Visual Studio
I have a few other problems not related to code lose, like random crashing and wizard disappearing.
I've just spent two weeks in VS 2010 beta 2 doing some serious prototyping work. It all went pretty smoothly, and I really like VS 2010. At the end, I moved all the code back to VS 2005 and integrated it with my current project. My experience:
Moving the code back to 2005 was pretty easy. I did try not to use any C# features from 2008 or 2010. The only thing I missed was C#'s implicit properties, but those are easily fixed.
Yes, the project and solution files are not backward compatible. To migrate back, I just created new projects in 2005, and pasted the source files in through Visual Studio. Worked like a charm.
I did find one thing that would consistently crash 2010. If you use the splitter to view two different sections of a file at once, and cut-and-paste from one pane to the other, VS 2010 will roll over and die pretty quickly (not necessarily at the time of the cut-and-paste, but very soon afterwards).
There are some nice productivity features in 2010. You can drag a tab out and make it a window. In Windows 7, you can drag it to the top of the screen to maximize, or to the side to use have the screen. Dragging one file to one side of the screen, and another file to the other side, means you get the whole screen to edit two files, side by side. Very nice. (Even better on two monitors, but I was on a laptop.) The "Quick Find" dialog can now be docked -- that's a huge improvement.
As others have mentioned, use source control, but VS 2010 really is not unstable enough to be any more of an issue than VS 2008. Note that Team Foundation Server 2010 is also available in beta, and will be part of all MSDN subscriptions. It installs under Win7 and Vista. I'm using it for source control on my laptop! Team Explorer is integrated into VS 2010.
I am having severe performance issues when compiling a moderately large ASP.Net website in Visual Studio 2008 (targeting .Net 3.5). I know there are some tips & registry hacks for improving compilation performance in VS 2005, are there any for VS 2008? Specifically, it seems that VS 2008 is compiling the whole website every time F5 is hit, even when no files have changed in that project since the last compile, or perhaps there is some way to skip the validation stage?
Antivirus problems: Make sure that your Antivirus program excludes your project directories! Make sure that your Microsoft.NET directory inside of your Windows directory is also on the exclusion list.
IIS vs. "Cassini" : If you can, use IIS instead of VS's integrated web server (aka "Cassini"). Doing this will prevent the server from having to restart every time you run.
Memory: Do you have enough?
I'm guessing this is an ASP.Net Website project and not an ASP.Net Web Application project. You'll get better compile performance from a Web Application project so you might consider converting it.
For a Website project, you can open the Website in Visual Studio, right click the web site project node in the Solution Explorer and click Properties. When the dialog box opens, click the Build item and set the item labeled "Before Running Startup Page" to "No Build" or "Build Page". This will prevent Visual Studio from compiling all the pages in your site and improve your local development experience at the cost of reduced compilation. Probably a worthy trade-off in your case.
If you have a lot of stuff in App_Code, you may want to move (some of) it to a seperate assembly.
Try renaming your .suo file
Watch out for Dueling Assemblies (where was this article when I was having the problem =) ?), one bad reference was killing me before. I noticed this and other potential problems by looking at the output window during the build process.
.Net 3.5 Service Pack 1 made some big performance gains at least in terms of the IDE and switching from Code to Design view. I don't know if it affects the general compilation speed, but it is worth applying if you've not yet.
