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 ?
回答1:
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.

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.

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.

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.

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.
回答15:
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.
回答16:
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).
