Seeing an issue when debugging in Visual Studio. All of the values under watch, and in the hover over window show up incorrectly. the only values that show properly, are values that are local to the method I am currently stepping through.
For example the watch value for 'this' when debugging shows the following under value
0x00000000ffac0388 { btnBack=0x00000000ffaccf20 btnReply=0x00000000ffacd200 btnForward=0x00000000ffacd420...}
some other variables show this, even though the variable is there.
error: 'this.foo' does not exist
The machine recently had windows 7 64 installed, since then this problem has occured.
Visual studio has been reinstalled on this machine, and we verified that the settings in visual studio were exactly the same as a different PC that is the same machine and config.
We finally figured out what the issue was. The devenv.exe was being set to run in xp compatibility mode (sp3). Doing a rebuild of the project after removing the compatibility mode fixed the issue.
Can you provide a bit more information to help us track down this problem. In particular
What operating system was installed before upgrading to Windows 7 64 bit?
Did you install Visual Studio before or after the upgrade?
Is there any other version of Visual Studio installed on the machine?
If you set your application to be x86 specific does the problem still repro?
What language is your code written in (assuming C#)?
When facing weird debugging issues, I find that deleting the solutions User Options file (.suo) usually fixes the problem. You will loose your bookmarks, breakpoints, any special exception handling, and so on.
If that fails then clear all your Visual Studio "temporary" files. Check out the "Clear Recent" script at http://missico.spaces.live.com/blog/cns!7178D2C79BA0A7E3!370.entry. Modify it for your own needs. For instance, I dislike Flash, so you may want to remove the call to ClearStupidFlash and the other non-Visual Studio calls. Clear your solution then "rebuild all".
If the problem still exists, then something else is going on.

In Windows Explorer, whenever I try to open a folder that contains TypeScript files, explorer freezes and crashes. When I try to edit TypeScript files in Visual Studio, it allows me to do so until I save the file. When I save the file, Visual Studio crashes without any dialogs.
I tried completely removing anything Visual Studio related (uninstall, registry clean, etc.) and reinstalling. I also tried running Windows in safe mode, and/or running Visual Studio in safe mode, none of which work. Running Visual Studio as an administrator also does not work.
I know it is not an issue with the actual repo since these files work fine on several other developer machines. This functionality was working just fine a month ago, with no changes in updates or installed extensions.
I am running Visual Studio 2015 Update 3 (14.0.25431.01) on a Windows 10 64-bit machine. TypeScript Tools for Visual Studio is at version 2.2.1.0.
Please let me know if there are any logs I can provide, I'm not sure where to get them.
The following update fixes this issue:
Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB4015438).
This is as of March 20, 2017.
UPDATE:
Many people have reported this issue as being the result of Windows Update KB4013429. This affects all Visual Studio installations. To resolve the issue, simply uninstall this update and restart your PC.
Old "Solution":
I solved the problem by reinstalling/cleaning Windows.
I know that's not a very good answer, but I wasn't able to solve the issue otherwise. Disabling antivirus shields did not work, and neither did running in safe mode. I think something in the registry may have gotten corrupted during a Visual Studio reinstall. Would love to hear any actual solutions if anyone else comes across this problem in the future.
I deleted a lot of stuff in the Registry under HKEY_CLASSES_ROOT\.ts, and now I can at least view folders in Explorer that contains .ts files, but I still cannot right-click them.
The biggest problem for me and my colleague was that Git and Visual Studio was unable to overwrite .ts files sometimes ("permission denied"), and we couldn't delete them manually either.
I'm not quite sure this has solved the problem permanently for me, but it seems so at the moment:
I used Handle to determine that SearchProtocolHost.exe had locked my .ts file, and wouldn't release until a few minutes later.
A few Google searches later, and I have now disabled indexing .ts files in Windows Search. So far, no more locks!
I'm getting the following error message
Cannot access a disposed object. Object name: 'MarshalingWindowFrame'.
This message came when I tried to load a SLN file into VS2013.
What is the reason?
I am using VS2013 Ultimate with Update 4 on Windows8.1 pro x64 bit OS (8GB RAM, 500GB HDD)
If you get that when opening a solution, either an addon is bugging out or (worse, but less likely) you found a bug in VS itself. Try safe mode and see if that helps.
If however you get the error when opening a form rather than the solution itself (remember opening a solution loads the various forms), there's a bug in an user control that's trying to access a disposed object. Remember that user controls run as binaries when hosted in VS, so make sure you put actual code inside guards that require you not to be in design mode.
Was that project created in the earlier versions or in the Visual Studio 2013 Preview? Because, if you update this project from Visual Studio 2013 Preview, you have to check the update procedure (http://blogs.msdn.com/b/lightswitch/archive/2013/08/12/upgrading-your-lightswitch-projects-raghuveer-gopalakrishnan.aspx) first, perhaps it can give some hints why this happens.
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.
I've been running Visual Studio 2010 (the official release) for some time now. Lately, VS will crash 10+ times during my 8 hour work day. In VS2008, crashes were common when working with large Xaml files, and while I experience some of that with VS2010, crashes occur when debugging, starting the debugger, stopping the debugger, and other random times when editing code.
I've looked through the problem reports, and the one I've found that occurs most frequently is:
Description

I'm running Windows 7 (x64). Hoepfully someone has come across this problem and has found a solution. I plan on reinstalling VS2010. Hopefully that takes care of the problem.
Do you think you have installed any extra Extensions which might lead to frequent crashes?
You can try
Devenv.exe /SafeMode
to start in Safe mode. You can also try
Devenv.exe /Log
Which will log all activity. Have not tried this so don't know What activities are logged.
Visual Studio 2010 Command Line Switches
I was having a similar problem and this helped me
http://connect.microsoft.com/VisualStudio/feedback/details/618802/visual-studio-random-frequent-crash
Running this from the command prompt seemed to fix it. It hasn't crashed for the whole day today.
regsvr32 c:\Windows\System32\ole32.dll
I had similar issues with Visual Studio. The problem was the service pack which for some reason was not installed properly.
I had to reapply the SP1 using the Repair / reapply option. This kind of fixed my issue.
Also make sure to reboot the system.
Just to help people who search it: It was webex instant messenger related part, but not Cisco itself. The cause was a component in Studio Power Tools relevant to integration with messenger. Reinstall power tools but without messaging integration.
In other occasion it is almost always a corporate antivirus authentication helper thing. It required to manually remove registry entries which cause background TFS logins break the studio at random moments.
I had the "Microsoft Visual Studio 2010 has stopped working" error, imediately when Visual Studio 2010 was starting. Fault module was clr.dll in my case. Only rebooting helped sometimes.
I solved it by removing .NET completely and reinstalling it.
Be aware that if you updated to .NET 4.5 this includes .NET 4, so you have to remove and reinstall .NET 4.5
I know why it could be crashing. Code it self. Have you tried to debug the failed instance of VS2010 with Vs2010? If the xaml designer crashed anywhere in your code you should be able to see the stack trace. Also, try to load the same xaml into Blend 4 and then run the vs2010 on Blend when that crashes. I've had some good results debugging Vs2010 crashes like that.
There are so many things that can cause studio to crash.
I'd look at everything from video card drivers to whether the RAM is stable.
Note, there is a microsoft connect but on this exact issue at: http://connect.microsoft.com/VisualStudio/feedback/details/634162/devenv-exe-frequent-intermittent-crashes-fault-module-name-ntdll-dll
You might vote on it or add your own information to the report but the very first thing I'd do is update my video drivers. One place I was at had a lot of issues with 2005; it would randomly crash just displaying the design surface or when opening a few too many code files; but once we got decent video cards and the appropriate drivers installed it worked flawlessly.
I disabled “Options"-"Evnironment"-"Add-in/Micros Security"->"Allow macros to run", and fixed the problem.
I think I just solved a similar issue on my computer, but probably not the same cause. It was related to TortoiseSVN (I think visual loads the tortoise DLL because it is integrated with the explorer, even if I don't have a specific visual studio plug-in). I upgraded TortoiseSVN (from 1.7.8 to 1.7.11) and it didn't crash for a few hours (I also had a 100% repro case when closing visual studio which does not happen anymore). Maybe there is some way to check what DLLs are loaded by visual studio to troubleshoot what are the candidates for upgrading/uninstalling, but I didn't go this far.
Hope it can help someone else.
While developing C++ code, Visual Studio 2010 started crashing frequently and at random times after I enabled the Task List.
As an alternative to using the Task List, I am now simply using the Find in Files tool (Ctrl+Shift+F) and searching for the string TODO as an alternative.
i was having a similar problem. visual studio 2010 was crashing. when i attached, it said it had a read access violation in ntdll.dll
closed all my open instances (there were 5) and it stopped happening.
Today I had this error, in my case it was because Microsoft released the update (KB2858725) the FrameWork 4.5.1, which the download and installed,
However this is definitely addressed by performing the following steps:
FrameWork 4.5.1 download (KB2858728) => NDP451-KB2858728-x86-x64-ENU.exe-Allos
http://www.microsoft.com/en-us/download/details.aspx?id=40779
Install the downloaded software (KB2858728)
Try Vs, but give the same error.
Uninstall the downloaded software (KB2858728)
(this task fully cleaned upgrade giving problems (KB2858725)
Install the downloaded software (KB2858728) again
Try Vs, this time if it will work
NOTE: NEVER! install update (KB2858725)
Logging helps indeed. I have the same problem with crashes. Since there could be numerous reasons and lots of log data, I wrote this .bat (Win7 x64, VS2010 Express) to keep logs organized and easy to analyze:

I had the same problem. I cleared my settings. Configured environment to use C# development settings. Then i disabled all extensions against which disable button was present. I enabled them one by one while opening, running and closing solutions. I found the offending extension to be .Net reflector v 8.5.0.179 by red gate. I had VS2010, VS2012 and VS2013 all installed on my windows 8.1 enterprise 64bit. All of them had the same issue. Whenever i closed the solution VS would crash. Hope it helps.
Following my last question (see: Problem in hosting ActiveX on Vista (in a Visual Studio 6 C++ application)) I ran into a strange problem. I hope this’ll be a simpler issue to the experts here:
Each time I run certain application like iexplorer or firefox, the Visual Studio 6 suddenly opens up in debug mode with a message “User breakpoint called from code at 0xSOMETHING”.
I can press F5 to continue but the applications run slowly and needless to say I have no wish to debug these applications…
My guess is that when I worked on my VC++ application I placed breakpoints at windows methods like CAxDialogImpl::Create(), AtlAxCreateDialogA() etc’, and for some reason it was kept somewhere.
Of course I now removed all the breakpoints and re-compiled the project but still this keeps happening!
I checked in the tools->options but the “Just-in–time debugging” is not marked.
Any idea?
(I use Visual Studio 6 which I installed on Vista)
Thanks a lot,
Erik
Not sure this helps but anyways:
Try disbaling the default debugger option. (It says Dr. Watson but it depends what you have set as the default debugger)
http://www.bridgetonova.com/2007/09/how-to-disableenable-windows-default.html
Also as per this post Visual Studio 6 is not supported on Vista. Only Visual Basic is.
http://www.itwriting.com/blog/167-visual-studio-6-on-vista.html
You should probably re-ensure yourself that you have removed all calls to DebugBreak() and manual break-points. Also try to ensure that when you recompile you re-register everything to point to the right places (i.e. the activex pointed to by the guid in the registry is actually the latest recompile).
