I'm building a project in Visual Studio 2010 and the build fails because it cannot copy the assemblyname.dll file from obj to bin folder. The exact error message is:
Error 7
Unable to copy file "obj\Debug\AssemblyName.dll" to "bin\AssemblyName.dll". The requested operation cannot be performed on a file with a user-mapped section open.
I think this is because the previous file in bin-folder is not accessible. When I try to delete the file manually, I get an error "The action can't be completed because the file is open in another program". If I try to see what application locks the file with Unlocker, I don't get any results (No Locking handle found).
If I restart Visual Studio, the error goes away but happens again after a build or two. Goes without saying that this is seriously slowing me down. Any advice how to start solving this?
VIsual Studio 2012 on Windows 8. I was receiving the same error message on my project. Restarting Visual Studio or cleaning the obj folder manually did not help. Finally I closed all open files (Windows -> Close All Documents) and the problem went away.
This behavior was due to a newly installed Visual Studio extension called Visual Studio Achievements (http://visualstudiogallery.msdn.microsoft.com/bc7a433b-b594-48d4-bba2-a2f24774d02f)
I noticed that the .pdb file was locked by FxCop (using Unlocker) and I think that the Achievements -extension uses it. After disabling the extension I've no longer got the error mentioned above.
This bug has been fixed in recent versions of the extension (>1.7). It was released as a beta, btw...
This behavior of VS happen very often even on my computer (and on computers of my coworkers).
In my experience it happen more frequently when:
I have some form opened in design when i compile
I stop the execution od the application by pressing the "stop" button
in VS instead of exiting the application
So, closing the form in design before compile, and exiting the application instead of stopping it, somewhat mitigate the issue... but it still happen :-|
My computer is Win 7 x64 SP1 with VS 2010 SP1, 8Gb ram, and no swap file
Platform: Windows 8 Pro, Visual Studio 2012
I found that I receive this error when I am accessing the folder in Windows Explorer.
I was creating PDF documents with Visual Studio 2012. To review the sample document I would right click in Solution Explorer and use Open Folder in File Explorer.
On Windows 7 I would get a SYSTEM.IO error if the actual PDF document was open in Adobe Reader which is expected. With Windows 8 I found that I receive the above error if I have the folder open. I suspect there is a conflict with the Windows 8 preview.
If I close the folder and run the program it works fine.
Check if you open the dll in visual studio.
I open the dll in visual studio and this error happen!!

Our previous development systems used Windows XP and Windows 7. Debugging C++ DLLs from Visual Studio worked great.
A recent move to Windows 10 has resulted in an annoying problem. We can debug once (using F5), but the 2nd time results in a linker error:
MyProg fatal error LNK1201: error writing to program database 'MyProg.pdb'
Trying to delete the .pdb manually in Explorer while Visual Studio is still open results in the error:
The action can't be completed because the file is open in devenv.exe
It doesn't matter whether you hit a breakpoint or not. Just start debugging once results in the problem. Re-starting Visual Studio resolves the issue (in the sense that you can debug once, but then you get the problem again).
If relevant:
x86 Visual Studio 2003.NET
targeting another x86 application
x64 Windows 10 Pro v1803
After hunting around for several hours some related, but unanswered, questions were found. Following suggestions in this MSDN article, along with some debugging of my own, this solution works:
Download FreePDB, a script written by MSDN user Toni76 (thanks Toni!)
Copy this script to a local folder (say C:\Apps\FreeDPB)
Download the latest version of SysInternals tool Handle (currently v4.21)
Copy handle.exe to C:\Apps\FreeDPB
NB! From the command line, run handle /? once. This is to agree the EULA. The script will not work if you skip this step!
Open Visual Studio, then Project > Properties > Build Events > Pre-Build Event
Set Command Line to C:\Apps\FreeDPB\freepdb $(ProjectName)
Set Description to Delete lock on PDB
...and now you don't need to restart Visual Studio to debug a 2nd time!
From comments, this works with multiple versions of Visual Studio on multiple versions of Windows.
Update
A more radical solution is described here which involves replacing a core Visual Studio DLL (NatDbgDE.dll). This solution only works for Visual Studio 2003 SP1, though.
In my case it was due to "Process Explorer" program, which was open alongside with my Visual Studio(I used it to check some properties of the exe I've created). After closing it problem solved.
So my Visual Studio 2010 is extremely slow (and sometimes freezes) when I have a particular file open and attempt to compile and run the project. I have to open the Task Manager and kill the process for Visual Studio to regain control. If I close this file, and open any other file in the Solution Explorer in my project, Visual Studio compiles and runs the program just fine. The build succeeds, but Visual Studio just freezes after that. If I attempt to do anything in the IDE, Windows will tell me that Visual Studio is not responding. I've tried commenting out everything but the bare essentials in the file that's causing the freezing, and that didn't work. In order to get my program up and running, I have to close the file and then build the project. Visual Studio will then build and run the program in a timely manner as long as the particular file is not open. This only started a few days ago, and I haven't made any changes to the code that could have done this, nor have I updated or installed anything else onto my computer. Any ideas would be greatly appreciated. Thanks.
I fixed this. What I did was run devenv.exe /log and looked through the log. It had the following warning in it: "The CTM file is out of date and should be deleted and rebuilt, but the file 'C:\ProgramData\Microsoft\VisualStudio\10.0\1033\devenv.CTM' could not be deleted." I went and deleted this file, and it did the trick. Now even with that particular file open, Visual Studio builds and runs the program just fine.
I'm running Visual Studio 2012 (version 11.0.61030.00 update 4). When debugging a local console application I get the following error when I start debugging (F5):
---------------------------
Microsoft Visual Studio
---------------------------
Error while trying to run project: Unable to start debugging.
The object invoked has disconnected from its clients.
---------------------------
OK
---------------------------
This only happens if I leave visual studio alone without debugging for a couple minutes. If I close visual studio and re-open the error goes away (until I leave it untouched for another couple of minutes). Has anyone experienced this? I can't find any threads of other people experiencing it.
This may be a possible answer for the problem.
Some from the answer:
Check which files were changed (why and how) after update from a source control engine
Review the list of extensions and plugins. Try to disable all or some of them
Close Visual Studio and kill all the development processes: devenv, mspdbsrv, vcpkgsrv, msbuild, msvsmon, vshub, vstest etc
Remove .suo, .ncb, .VC.db, .VC.VC.opendb files of the solution as well as .vs directory, which sometimes cause problems
Remove project setting files, sort of YourProjectName.vcproj.DOMAINNAME.LOGINNAME.user or YourProjectName.csproj.user. The setting file name depends on a project kind you use
Run "C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe" /setup or "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe" /setup for x64 environment
Just Close the VIsual Studio and start again the project.Its work Perfectly for me.
Thanks
While restarting Visual Studio does provide a workaround, it doesn't solve the actual problem. In my case, I was working with a C# solution in VS2017 and the following resolved the issue:
Close Visual Studio
Delete the .vs folder that was created in the Solution's directory
Re-open the Solution
I corrupted my App.config file with NLog settings without section Handler in the top of the document. Gist is check out your config file settings either corrupted in format or not properly handled any section. once I remove corrupted config section, it did not raise the error again (VS 2017)
Hope it helps!
In my case I have just reinstalled Windows 10 and so the Visual Studio 2022..
My project was targeting .net 5 SDK, but I only had .net 6 SDK installed. The solution was to install earlier version of the SDK.
My Visual Studio began crashing at start-up. In my search for finding a remedy, I found these two suggestions, but neither worked for me:
Launching Visual Studio while running in safe mode, and
Running repair on Visual Studio.
However, I found that if I logged into a different Windows account, Visual Studio was able to run from that account without crashing.
Here is an error code that that I observed in the crash report:
LCID: 1033
Can anyone provide a solution for returning my Visual Studio to working order?
For me it turned out to be the plugin that GitExtensions installed into Visual Studio 2013.
-- UPDATE: try this before uninstalling GitExtensions
#Enceradeira proposed in the comments to uncheck the Show current branch in Visual Studio option. In GitExtensions, you get there via Tools -> Settings -> Appearance:
-- END OF UPDATE
After uninstalling GitExtensions and reinstalling it with all VS plugin unselected my VS runs smoothly again.
I even put together a blog post about this issue because it bugged me so much.
Since you're able to run with another user login, something may be wrong with your local settings, you can try to reset them: devenv /resetsettings in Start menu -> Run.
Warning: this will restore visual studio to default settings.
In my case VS used to crash on a single solution. I resolved the problem by deleting the respective solutions's user file: SolutionName.suo
My colleague recently experienced a problem with Visual Studio 2013 crashing on start-up. Unfortunately, we found that the approach recommended in the answer by #Arun M did not solve the problem:
devenv.exe /ResetSettings
...however, using a different command line argument did:
devenv.exe /ResetUserData
An easy way to run devenv.exe is via the Visual Studio command prompt; on Windows 10, it can be found here:
Start Button => All Apps => Visual Studio 2013 => Visual Studio Tools =>
VS2013 x86 Native Tools Command Prompt
For more about these command line arguments for devenv.exe, see this answer to this related question: How do I truly reset every setting in Visual Studio 2012?. ⚠ In particular, please note the cautionary statement in that answer about the /ResetUserData command line argument!
Try to run VS as administrator. That's necessary in my case.
If coincident to these Visual Studio crashes you are getting "Heap corruption" (Exception code: 0xc0000005) errors in your Windows Application log (Faulting module name: WindowsCodecs.dll), here is something worth checking into: A faulty WIC component within Expression Blend can cause ALL versions of Visual Studio to crash upon launch, as well as cause Internet Explorer to crash upon visiting many, if not most sites. Even though Microsoft distributes this component, they call it a "non-Microsoft component". As such, a Visual Studio reinstall won't fix this,, an OS reinstall over existing Windows installation won't fix this, and a system file integrity check won't detect it.
If my case, the misbehaving codec was "C:\Program Files (x86)\Microsoft Expression\Common\Imaging\4.0.360.0\PSDCodec.dll", and simply unregistering this component got my Visual Studio working again from consistent startup launch crashes.
I post this in hopes this solution to one source of Visual Studio crashing might save others from the $500 Microsoft support incident fee and week of downtime this caused me.
I just changed the windows language in the bottom right to "EN", then started as admin. And it worked, interesting..
I had the very strange phenomenon that both Visual Studio 2010 and 2013 on a Windows 7 machine crashed when run in a remote desktop session, started from a Windows 10 pc. Debugging the crash showed a CultureNotFound exception. It was caused by regional settings on the Windows 10 pc, which could not be translated in something understood by Windows 7. I had language English(Belgium) with an Azerty keyboard. I added and selected English(UK) with an Azerty keyboard and the crashes disappeared. No other programs suffered from this.
For me it was being caused by Web Essentials and I was able to resolve by disabling it, restarting VS, enabling it back , restart again. Works now.
I had a crash on startup (or soon after startup, before opening any solution) occurring in git2-msvstfs.dll, caused by placing a 3GB temp file into a directory within my solution. Deleting the file fixed it.
Once I accidentally pressed a random key combination (maybe something like ctrl+', but I didn’t realize I was holding ctrl down so I forgot what keys I hit by the time I realized something bad had happened) that resulted in VS Professional 2017 15.3.5 crashing within half a minute. After relaunching, I found that VS would be interactive for a few seconds before it would crash within half a minute. It was really too fast for me to try to figure out what I had accidentally activated or for me to disable it before VS would crash. Also, it would even crash if I didn’t open any solution, so I figured it was not something that deleting a .vs (per project/solution Solution Explorer/open files state) folder would fix.
To fix, I followed Arun M’s comment and renamed my %LOCALAPPDATA%\Microsoft\VisualStudio\15.0_3f4d04be folder. You will need to adjust the path for the edition/version of VS that is crashing. On my machine, I think 15.0_3f4d04be is Professional and 15.0_0fed6c59 is VS Community Edition. You’ll probably have to guess based on the folder’s modification timestamp which is probably going to reflect the date you last used that edition of VS.
After renaming the versioned dotfolder, VS launched without crashing. It started with default settings but automatically restored some of my settings through the cloud sync stuff after a minute of running and it even remembered my account information so I didn’t need to sign in.
I did not need to rename my %LOCALAPPDATA%\Microsoft\VSCommon folder (which Arun M had also suggested).
I had a similar problem, both VS2015 and VS2013 would crash at startup. Tracked it down to an application I installed which put .net 4.7.2 on the system. Once i removed that app, removed .net, and reinstalled .net 4.6, Visual Studio started working again.
Visual Studio 2008 has been very stable for months on my computer.
This morning when I double-click on any .xaml file to open it, or even click on the tab of an already opened .xaml file, Visual Studio says "initializing toolbar" in the status bar and then 20 seconds later fully closes the whole application without any error message.
Other files (e.g. .cs class files) I can open fine.
Has anyone experience this or know what I could check/change to be able to use Visual Studio to edit .xaml files again?
MORE INFO: I can also create a new project and create and edit .xaml files fine.
MORE INFO: I can edit .xaml files in other modules (projects) fine.
MORE INFO: Everytime it crashes, this event is registered:
.NET Runtime version 2.0.50727.3053 - Fatal Error in executable module (72555E00) (80131506).
(odd since I have .NET framework 3.5 installed)
MORE INFO: It is only in one module (project) that .xaml files cause Visual Studio to crash. Even creating a new UserControl in that module crashes Visual Studio.
I get this occasionally (with .xaml and .resx files) and find that if I delete the solutions .suo file things work fine again.
[The suo file just contains per user settings like recently opened files etc so it's nothing important and will just be recreated when you next open the solution.]
I've been getting the same issue whenever I try to access project settings for a C# project.
Found additional information about this:
Here: http://blog.fryhard.com/archive/2008/11/26/visual-studio-2008-closes-at-build-outlook-2007-add-in.aspx
And here: http://social.msdn.microsoft.com/Forums/en-US/vsto/thread/99e124d0-c5d7-49c0-b1dd-71328f9a6571/
Apparently it's a bug in the core CLR engine that causes the entire CLR to crash if certain types of assemblies are loaded in a certain order.
Most of the time it appears to be directly related to the Visual Studio add-in called PowerCommands - uninstalling PowerCommands will make the problem go away.
And (we hope) it's supposed to be fixed for .Net 4.
This sounds very similar to the issue I had when I first installed VS 2008. Unfortunately, after hours of research, I ended up reinstalling the IDE (with my fingers crossed). No problems since then, but it's obviously not the most enjoyable way to solve the problem.
What is likely happening here is that one of the controls referenced directly on indirectly in your designer is stack overflowing during the designer process. Because the designer is hosted in process a stack overflow by one of the components will take down the designer and VS.
Try attaching a debugger to VS, break on first chance StackOverflow Exceptions and open the designer.
