When trying to execute from within Visual Studio 2008 your application and you get the (uninformative) message "The operation could not be completed".
The solution to this is to turn off the "Visual Studio Hosting Process".
The problem with turning off this "hosting process" is that all the "run and rewrite" functionality is no longer available. OK, so this isn't a big deal, but I'm always getting this message no matter what machine I use (and it might be nice once in a while to use the rewrite and execute functionality).
Am I doing something wrong? How come this "feature" within VS seems to complain so readily? Do other people have success with enabling the hosting process and making use of it?
The problem with turning off this "hosting process" is that all the "run and rewrite" functionality is no longer available.
The Visual Studio Hosting Process is not needed to allow Edit and Continue. It is used for "Design time expression Evalutation" in the case where the project is a dll rather than an EXE. It is also used to provide debugging for partial trust scenarios. See the documentation for everything it does.
It is highly unlikely it does anything you need, so don't feel bad turning it off.
Is your project output folder set to a network share?
If so, try changing it to a local folder and see what happens. It appears that VS is not always able to terminate the process if the host exe is running from a share.
The other possibility is that the project is open and running in debug mode on another instance of Visual Studio - although I suspect you will allready have ensured this is not the case.
I honestly have never seen this message and I work with Visual Studio for at least 8 hours a day. Is this reproducible on other machines? If so is there anything weird or abnormal in your code that could cause this to crash?
I use 4 different machines and have got this situation on all of them. I understand what is causing the problem - it is that the VS hosting process isn't terminating after the first debug session ends, which means that the next time that you try to compile the exe the hosting process is locking the exe and preventing compilation. Another solution therefore is to use Task Manager to kill the VS hosting process and compile and debug as normal but thats even more of a hassle!
I can't think that its anything in my code that would be causing this - its probably a VS issue itself isn't it?
Here's the anwser: disable "Enable he Visual Studio hosting process" in he debug tab of your projects properties.
I found it here:
http://social.msdn.microsoft.com/Forums/en-US/vbide/thread/40d2d241-a0c0-4137-9da9-e40611972c0e/
There are several causes and workarounds regarding to this problem and you might try the following ones that are useful most of the time:
Delete the "Your_Solution_FileName.suo" file and restart Visual Studio.
or
Right click on the project and select Unload Project and then click Reload Project by right clicking on the project again might also fix it.

I am using VS 2013 ultimate, working on a project with Team Foundation Server. The problem is, every ten seconds, it hangs for up to 5 seconds, I am not compiling or anything, just writing code. Devenv.exe process jumps to more than 25% CPU and 670k of RAM. I have looked at the output from the JavaScript Language Service, and it constantly checks and says Referenced file 'D:\tfs\xxx.aspx' not found. Text search of the filename xxx.aspx in entire solution turns up nothing and I have the latest version. I think this is the reason of the spikes, does anyone know how I can turn off this feature in VS 2013?
EDIT: I have looked at other solutions, Browser Link is closed, I have the latest update
EDIT: I have found the solution, but I dont think it will really help anyone else. One of the guys referenced a hard drive path on top of a javascript page, and since the project is tens of thousands lines, cpu spiked as Visual Studio was searching it. Deleting the references helped in my case.
To narrow down this issue:
Try to disconnect from TFS server. (In VS→ Team → Disconnect from
Team Foundation Server) Check whether this abnormal phenomena still exist.
Use devenv/resetuserdata command to clear user settings of VS,
details refer to this blog: VSTS Tip: devenv /resetuserdata
If you are using proxy in your machine, try to disable the proxy
settings.
If there is anti-virus in the machine, also try to disable it.
When I debugging in VS2013 update3, msvsmon.exe crashed when hit at a breakpoint.
It shows "The debugger's worker process (msvsmon.exe) unexpectedly exited. Debugging will be aborted".
I'm not using remote debug.
Is it possible to shut down the msvsmon.exe to avoid calling it when debugging ?
Deleting all of the breakpoints solves the problem when I hit this error. Disabling the breakpoints was not enough - they had to be deleted.
I was able to attach to a process numerous times. Once I added a conditional breakpoint (with a few checks), I started getting this error when attempting to attach to that same process.
The error provided in the question is one problem. I also received an error stating that a debugger was already attached when I tried again. Either way, deleting breakpoints solved it.
Try turning on Options > Debugging > General > "Use Managed Compatibility Mode"
I got this error/crash too while debugging and trying to inspect a variable with 50 MB of text data in it. This option worked in both VS2013 and in VS2015 to allow me to debug and inspect the variable with large data.
A couple of things that worked for me:
Try Closing VStudio and relaunching.
If not, reboot helps.[I know thats generic, but its worth a shot]
Disable unnecessary break points.
I had this error also, and I too have Astrill installed. Completely uninstalling Astrill fixed the issue.
I reached out to Astrill support, and they answered (within 2 hours) saying the correct fix is to hold Ctrl and press the "Help" button on the Astrill application, and then choose "Uninstall LSP". This has fixed the issue without needing to un-install Astrill.
I don't know what LSP is, but I presume it's some sort of proxy.
In my case, it was caused by a VPN software. It changed my hosts file and my localhost was not 127.0.0.1 anymore.
So check your localhost in the hosts file (e. g. %WINDIR%\System32\drivers\etc\hosts) and make sure it is 127.0.0.1.
This error just occurred for me with visual studio 2015 RTM. Deleting all the breakpoints resolved the "The debugger's worker process (msvsmon.exe) unexpectedly exited. Debugging will be aborted" condition.
So If you clear all your breakpoints, in your version, you will not need to avoid using MSVSMON.exe.
I was using the OzCode debugger extension. Unfortunately they don't have a way to completely disable the extension - you can only disable certain features - so I had to completely uninstall it to confirm it was what was contributing to the crashes.
I got the same error. No effect after deleting all breakpoints and repairing Visual Studio (I have 2013 Community Edition). The problem was the Bitdefender software. I have Bitdefender Internet Security 2016 and had set Active Thread Control (Modules->Antivirus) to Normal level. But after setting this settings to Permissive the error doesn't show up anymore.
This error occured to me, when I tried to debug with Visual Studio / Service Pack 3, when Service Pack 4 was already released. After updating to the Service Pack 4 I was able to debug.
So, try installing the newest version of Visual Studio

This (or something that manifests in exactly the same way) is still an issue in VS2017. In my case it was caused by a dependency being too large to debug. The dependency in question was a generated client for a large REST API. I was able to debug again after slimming down that dependency.
Here's yet another answer: I changed my project from "Platform Target: Any CPU" to "Platform Target: x86". Went from needing about 5 attempts to debug to working every single time.
I had previously tried every suggestion in this thread: I reinstalled, I killed all breakpoints, and looked for fishy software interactions.
I started getting this exact error today in my VS2019 project. Attempting to expand/inspect simple data structs in VS debugger would make it freeze for a minute and then I'd get that "The debugger's worker process (msvsmon.exe) unexpectedly exited. Debugging will be aborted" message:
If I add msvsmon.exe process to windows defender exclusions list, then the problem disappears.
I hit this in Visual Studio 2019 (16.4.3) (C++) with a cause that I have not seen mentioned: I had accidentally added a Watch with incorrect syntax that was attempting to instantiate a singleton rather than returning the existing instance.
Repeatedly choosing right click > Clear All in the Watches view while debugging fixed the issue.
Fixed by changing Options->Projects and Solutions->Web Projects -> Use 64bit version of IIS......... to False.
In my case i am using the wcf Service on the wpf application and inputting parameters from here.The Wpf Application Execution on Facing this error "The debugger's worker process (msvsmon.exe) unexpectedly exited. Debugging will be aborted".
That case i am hosing the Wcf service and run the wpf application exe
In this type of Execution on I didn't Facing any Error like -- "The debugger's worker process (msvsmon.exe) unexpectedly exited. Debugging will be aborted"
please,try this proceed error solved because some execution process didn't supporting the debugging..... we are removing the Debuggers on also we face same error.
that case on helped this process.......
I just experience this with VC2017 Community Edition 15.7.2. Turning off the Microsoft Symbol Server lookup while debugging fixed it for me.
I've just had the problem in VS 2015. I hadn't noticed that one of my breakpoints was bogus - I had inadvertently pressed F9 to set a breakpoint when the disassembly window was showing in the previous debugging session. The solution was simply to delete that one bogus breakpoint - I got to keep all my others.
I tried almost every answer in here, but for my case, nothing worked.
Switching to 32-bit just made Visual Studio 2019 crash instead of msvsmon.exe crashing.
What did work for me is to set a very early breakpoint and use that opportunity to close the "Parallel Stacks" window. I didn't need that anyway, but it was open by default in my layout.
In my case, I had this error when I had the "Locals" tab opened during debugging and hitting a breakpoint. For some reason VS might've been unable to display one of the local variables. The error disappeared when switched to a different tab before hitting the breakpoint where the error was occurring.
My problems started after moving a project to a new folder. I wasn't having any luck with any of these answers using VS2019. I even deleted the entire .vs folder thinking maybe something got corrupted. No luck.
But on a whim I tried starting the project with CTRL-F5 instead of just F5 and that actually worked. It's consistent. CTRL-F5 runs fine. F5 gives me the msvsmon.exe error.
I have no idea what's going on, but at least I can get the project to run again.
This problem is at least 1 1/2 years old maybe more. Today is 6-11-22 and I have the problem in Ms Studio Pro 2022 with a fresh install of windows 11 not much of anything else in the computer. Then I uninstalled it and install Ms Studio Community 2022 put in 1 breakpoint at the beginning and I got the error.
Today 6-12-22 I reinstall Ms Studio Community 2022. For some reason I switch from x86 to x64 went through a about 1000 changes of errors and a crashed form1.resx file thank goodness for a backup I had or I'd be done again. anyways so far have several break points with no problems.
I deleted all my watch variables. That fixed the problem for me.
I know it doesn't directly address the error, but as a workaround, I'm using the Rider IDE from JetBrains, and am not encountering the error (code, system, etc. the same).
Visual Studio version: Professional 2017, 15.5.4
Rider version: 2017.3
None of the other answers worked for me, when I encountered this error. If you are not actually remotely debugging, you can use another editor until you figure out the problem or it resolves itself (the latter was the case for me).
I have an issue with Visual Studio 2010 and an ASP.NET 2.0 project.
I have searched StackOverflow for a possible solution to my problem, but even though there are alot of articles related to the Visual Studio debugger, none specifically solve my issue.
Every time I start debugging, Visual Studio tells me that "The breakpoint will currently not be hit. The source code is different from the original version.". In the past when I got this problem, I could solve it by doing a Clean Solution. Or if that didn't work, I could always restart Visual Studio or my machine and the problem would be gone. This, however, doesn't work anymore. The solution cleans and I can rebuild, but the debugger still complains about the source.
I found that if I delete the folder "root" in "C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files", the problem is temporarily gone but only the next time I start the debugger, and only for the breakpoints that are currently set in the project. All breakpoints I add when the debugger is running are also not being hit due to the source/original difference.
I don't know how to solve this issue permanently because I don't want to delete that folder every time I have to start a debug session.
I also have a few ASP.NET 4.0 projects that debug just fine.
I use Windows 7 Enterprise (x64).
If someone has a suggestion I would very much appreciate it :)
Try this
Right click solution.
Click "Property"
Go to: "Common Properties" -> "Project Dependency"
Select your "project" from drop down list
Check every item in list of "Depends on"
Click "OK"
Now Open "Task Manager"
And kill all worker process i.e. "w3wp" in case of iis7
Or Kill all "WebDev.WebServer40.exe" process
Now run your application.
My Visual Studio 2010 Professional hangs up 99.999% of the time when I try to open a website as "Remote Site" through an HTTP address. However if i open the site through a unc path instead of through HTTP, it works fine. Of course that is not always feasible, for example when working from offsite. The same sites (assuming they are not NET40 sites) work fine in Visual Studio 2008, so I'm pretty sure it is not a problem with the Front Page Server Extensions.
If i run 2010 in /safe mode, it opens the projects fine. So i figured maybe it was one of my installed extensions. I therefore disabled all my extensions and tried again, but it still hangs up. So it is apparently something in Visual Studio itself that is different between safe and normal modes.
I ran it in logging mode, and checked the log but did not see anything that stuck out to me. The log is uploaded here: http://pastebin.com/aUnVanB1 .
The exact symptoms I am seeing are that when i click on the project name, it pops up and asks me for my credentials. I enter those, and click OK, and it then loads the solution explorer, and i see the tree view, but then it just hangs with the progress dialog that says "Preparing Solution...". The progress bar keeps cycling, but it never finishes loading, and the spot where the properties window would be in the VS UI is completely unpainted, with just a blank, empty, white space.
Any one have any clue what else i could do to try to figure out why 2010 hangs when attempting to load websites via HTTP? Thanks!
Thanks for your question... you gave me the right clue to solve my problem!
My VS 2010 was hanging (in fact was very slow to get available) when I was openening a solution containing a remote website and I was due to press Escape a few times to cancel the pending operation... As you suggest I tried to open such a solution with /safeMode and VS2010 became available quite instantly.
So as you pointed the VS Extensions... I checked mine (all from Telerik): opening the extension manager I discovered that some updates where available. I thought the extensions updates were automatically proposed and so never checked that before. In fact, you need to manually check with the extension manager if some are available.
I've updated all my Telerik extensions... and now I may open normally all solutions including a remote website.
Thanks a lot! Perhaps... you need to updates your extensions???
Check you network order preference in Windows.
I had a similar problem where DNS would cause a hang of 1 minute before trying again (and again and finally on the next network).
Under Network, Advanced Settings (WinXP):
I'm having a problem where VS2010 Ultimate is freezing up every so often for several seconds before returning to normal operation. This happens several times during a session, and is obviously very annoying. I haven't been able to pin it down to any specific activity-- it seems to hang whenever I scroll around in a document, open/create a document, basically anything. Anyone else have this issue or know what might be the cause?
Incompatible add-ons or system configurations can cause Visual Studio issues (performance issue, error, etc).
Fortunately we can try to troubleshoot the issues by referring to the Visual Studio activity log.
Simply run the following command to run Visual Studio 2010 and log its all activities.
DevEnv.exe /log
The log file will be generated to:
XP
%USERPROFILE%\Application Data\Microsoft\Visual Studio\10.0\ActivityLog.xml
Vista & Windows 7
%USERPROFILE%\AppData\Roaming\Microsoft\VisualStudio\10.0\ActivityLog.xml
Once you run it, 2 files will be generated: ActivityLog.xml and ActivityLog.xsl
And when you open the ActivityLog.xml, it will contain something like this:
The problem was solved by deleting the user options file called SolutionName.suo.
Somehow it had gotten very big and probably corrupted. You will only lose your breakpoints and open files as far as I know, but rename it to be safe.
I know people have had problems with computers that are older or don't have as much RAM. I know my use of VS 2010 ultimate can run to 500 MB's sometimes and if you don't have enough RAM, then it will hang for a little.
I've had issues with VS2010 when debugging is running or if I'm opening files from a network drive. I'm not sure as I currently don't have any team server repos connected, but if you do maybe the connection to the repo might be an issue as well.
Turns out the issue was network related. One item in my solution was looking to a mapped network drive, which apparently didn't always respond fast enough.
My solution for that problem was beyond the scope of my thinking. I found it on this website, and it goes like:
Launch Internet Explorer. Go to Internet Options, then Advanced tab. Under the Security group, untick “Check for server certificate revocation“. You may need to restart Visual Studio.
My scenario is that I have network drives with references mapped via VPN. That should have to do with that.
I faced similar issue with Visual Studio 2008. I have not thoroughly investigated the issue though.
Reading your post it seems the behavior at your PC is really annoying, but for me it's not that frequent.
One thing I noticed, the frequency at which this happens is dependent on the RAM size and time elapsed since last setup. I came to this conclusion seeing the performance of machines of my colleagues.
I noticed that my anti-virus software tends to lock down my entire system sometimes. If you have an anti-virus application, you might try disabling it for a moment to see if it is the culprit.
I had a similar issue - that still happened after a /resetsettings, reinstall and using /safemode. For me, the issue was that Assembly Binding logging was turned on ago and I forgot to turn it off, it got to the stage where the log files concerned were >200MB and each append was taking ages...
Managed to find the issue with procmon from sysinternals. Suggest that anyone who comes across a similar issue tries procmon if none of the above solutions help.
My VS2010 would hang as well in a similar fashion.
DevEnv.exe /log would indicate it failed to load strings around the time it would hang.
Reinstalling VS2010 SP1 and deinstalling Resharper to install Resharper 7.1.3 solved the problem.
