I have just reloaded a project on visual studio (2019) that I was using a few days ago and the watch function in debug mode does not appear to be working anymore. I have normal debug flags (no optimisation and full debug information) and as far as I can remember I have not changed anything from the last time that I used this project (when the watch function was working normally). Apart from this, the code runs normally and without bugs.
When the code hits a breakpoint, although the local variables appear in the locals tab, when trying to view variables in the watch 1 tab, all variables (even those defined locally) appear as identifier "..." is undefined. Hovering over variables has also stopped displaying their value.
I have tried restarting visual studio, clean and rebuild, restarting the PC, opening a different project and creating a new project, but the problem persists for all of these.
Maybe there is a switch that I have changed accidentally since the last time it was working? Thanks in advance!
I managed to fix this by using the visual Studio installer and using the repair option under more->Repair. After the repair and a restart, the issue was solved.
I find that in different cases you need to have different exception classes enabled/disabled in the Debug -> Exceptions dialog, and it's hard work to keep reconfiguring this.
So, is there any way to save the Debug -> Exception setting and restore them later?
I'd like to have a couple of different configurations to load depending on my needs.
I am aware that the settings are stored in SlnName.suo, but so are a lot of other stuff and it's a daunting and risky task to fiddle with it.
The question refers to Visual Studio 2010, but I'd be interested to know if the dialog has been improved in this respect in later versions of VS.
According to the following article:
https://faithlife.codes/blog/2010/01/saving_debug_exceptions_settings/
"These settings are stored in the SolutionName.suo file that lives alongside your .sln file. Once you’ve configured the Exceptions dialog to your liking, close all the open windows, then exit Visual Studio. Make a backup of the .suo file and restart Visual Studio. Whenever VS loses your settings, close it down, overwrite the real .suo file with your backup, restart VS, and you’re back to debugging the way you want to."
Whenever my installation of Visual Studio 2010 Professional crashes while running my VC++ application, I lose all breakpoints that I set during that session (other breakpoints from previous sessions remain), leading me to believe that breakpoints are only truly saved on project closing. Can anyone confirm this, and offer a useful tip (other than occasionally closing and reopening my project)?
Note: By session I don't mean debugging session but just the time period in which the project is open.
Do you change your breakpoints very often? It is possible to Export breakpoints for later re-use:

Since some time I register an annoying behavior in Visual Studio 2010 SP1 under Windows Vista. Sometimes my user settings are lost on start up. This happens most of the time, when I had open the same solution parallel in two instances of VS and after closing both, the settings are lost on the next start of VS.
I do not change settings while running the two VS.
Did anyone experience the same behavior?
Of cource I saved my settings, but especially my keyboard short cuts cannot be fully restored, because I overwrote some global default short cuts. So that's what bugs me about it most. ([EDIT] This is an independent problem, see Microsoft Connect.)
Is there a way to get VS not to kill my settings on start?
VS overwrites user settings on close. If you want to avoid such problems, you should close an instance where you made changes last.
I have this problem where I open Visual Studio and the internal windows are scattered all over the place. None of them are docked; some that should be visible have become invisible and vice versa. I then have to spend ages getting the windows back where I like them.
It only seems to happen with some solutions and only appeared recently.
For the life of me I can't fix the problem. Has anyone else been through this?
Sounds like there is definitely a problem with Visual Studio retaining your settings between round-trips and possibly your Visual Studio settings profile in general.
The solution I'd recommend is firstly to reset all settings, secondly customize things to your personal preference and finally take a backup of those customized settings. The idea is that this settings backup file can be used later to automate a quick settings restore to a point you are happy with. The following steps show how to do this and hopefully should sort out even the most confused Visual Studio setting issues:
Close down all instances of Visual Studio.
Go to Start > Programs > Visual Studio 200X > Visual Studio Tools > and choose 'Visual Studio 200X Command Prompt'
Run the sligthly less well known 'devenv.exe /ResetUserData' command. With this command you will lose all of your Visual Studio environment settings and customizations. Because of this, the /ResetUserData switch is not officially supported and Microsoft does not advertise it (the switch is not described in the help for devenv.exe you get when you type devenv.exe /? in a command prompt). Importantly, wait for the resulting devenv.exe process to disappear from Task Manager or even better Process Explorer.
When the process disappears from Task Manager or Process Explorer, run 'devenv.exe /ResetSettings' which will restore the IDE's default settings and eventually start a single instance of Visual Studio.
Now in Visual Studio choose 'Import and Export Settings...' near the bottom of the 'Tools' menu to start the Import and Export Settings Wizard.
Choose 'Reset all settings' radio button and Next > Choose 'No, just reset settings, overwriting my current settings' and Next > Choose your personal 'Settings Collection' preference, I would choose Visual C# Development Settings here (Note: What you choose here has an effect on keyboard shortcuts etc. but you can always repeat this process until happy) and click Finish.
When you get the message that 'Your settings were successfully reset to XXXXXX Development Settings.' click Close then spend a good bit of time adding any personal customizations to Visual Studio such as opening windows you always want open, customizing toolbars and adding any toolbar buttons etc.
When you are finished with your personal customization and completely happy with your setup go again to Tools > 'Import and Export Settings...'
Choose 'Export selected environment settings' radio button and Next > Tick 'All Settings' and Next > Choose a file name and directory and click Finish to store a backup of your current settings in a .vssettings file.
In future if things go haywire again head back to Tools > 'Import and Export Settings...' and this time choose 'Import selected environment settings' radio button and Next > Choose 'No, just import new settings, overwriting my current settings' and Next > Either choose the name of your .vssettings file from the list (usually under the My Settings folder) or Browse.. to where you saved the file and Next > Tick 'All Settings' and click Finish.
Importantly, close the single instance of Visual Studio. Any future instance you open should retain your latest customizations.
Visual Studio corrupts its settings with regular monotony (always has done, I've been suffering from this since the Visual C++ days, and it's still a bugbear in VS2013).
Often this seems to be totally at random, but it's highly probable after a crash.
It will also lose any changes to your settings if Visual Studio doesn't shut down cleanly - for some reason instead of saving back the settings when you OK the dialog, VS seems to wait until it quits to write back your changes, so after changing options I always quit and restart to ensure the changes have been flushed to disk. Similarly you should never change options with 2 or more instances of VS running, as the last one to quit will overwrite the settings.
In particular, there is an easily reproducible case: If you launch two or more copies at the same time (by which I mean if you start up two or more copies, so they are all initialising at the same time), they seem to fight over the settings file and it becomes corrupted or resets to defaults.
The best two workarounds I've found are:
Never launch more than one instance at a time. If you need to run several instances concurrently, then wait for the first one to finish loading its Solution before you start to launch the next.
Always use Tools > Import and Export Settings to save your settings to a backup file, so that recovering from this corruption only takes a few seconds each time it happens.
Another smaller, but still rather irritating habit is that if VS is minimised when it is quit (e.g. by shutting down), it corrupts its window position information and the next time you run it, it will be maximised.
I had a similar issue when the My Documents folder was stored on a mapped drive. If I opened VS before mapping the drive, VS would act as if it was the first time it had been opened. I solved this issue by storing the environment settings on the local disk.
I just ran into this problem too (seemed to trigger after a windows update) where I kept getting some bogus window layout no matter what I did. The above suggestions didn't work either. But luckily the suggestions in: Why doesn't VS 2008 IDE remember my preferences? of deleting:
%APPDATA%\Application Data\Microsoft\VisualStudio\9.0\windows.prf
worked.
TP
Actually I worked out what the culprit was: previous VS crashes.
If one of my Visual Studio instances crashes for whatever reason - the next time I start up VS, I get a weird batch of settings. The behaviour depends on various factors, like whether or not I had other instances of VS open at the time.
I tried Peter McG's solution, still didn't help.
What ended up working for me was to delete my VS Solution User Options (.sou). Located in the same directory as my solution.
Only bad thing is you have to redo all of your settings. This included my exception changes. Not to much to change, but if you have a lot of customization it could be a real pain.
There must be something in that file messing everything up, but deleting the whole file is quick and easy.
Which solution you're opening shouldn't matter because those settings are not solution-specific. But I wonder do you maybe have Visual Studio 2005 and 2008 installed? If so, opening a solution created in 2005 will open VS 2005 and opening a 2008 solution will open VS 2008. You may have VS 2005 even if you didn't install it. For example, InfoPath 2007 installs a VS 2005 shell.
First I would position the windows where you want them, then do a Tools -> Export Settings and include only the window layouts. That way you at least have something you can revert to.
Then I would check Tools -> Options -> Import Export Settings and make note of where the "Automatically Save My Settings To This File" path is set to. Keep an eye on that file. Do you have any sync software that may be inadvertently overwriting it? Does it point to a non-existing location?
My issue is similar, but the result is the app crashes. The problem was this value
In HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0\MainWindow. It was set to "0 1000 -280 -100 3" probably due to having multiple screens and moving the UI around a lot.
Deleting this value allowed the app to restart successfully. It gets recreated on startup.
I'm facing similar issue. And it also only started recently, like, within the last 30 days or so. The only thing I remember changing in this period was updating Resharper 4.5.
I have experienced something similar. In my case the text editor colors (c# editor for example) are going haywire. The only solution that I tried and works for me is change color theme so something else and then back to what I want.
In my case its not the Window layout being corrupted but Intellisense offering code completion and pop-up help. Never had this issue for the last decade, now it happens 3 times a day at least. Win8.1, Visual Studio 2013, ReSharper 8 and now ReSharper 9 (in hopes the upgrade would fix it).
I now routinely have to
close the solution,
Tools/Import-Export Settings/Reset all settings
Close Visual Studio
Open Visual Studio Import my saved settings
RE-open the solution and continue working
I can then work fine again for quite some time until something goes awry... lets say a stack-overflow while I'm debugging. At that point I just know my settings are screwed and my Intellisense is dead again.
I'm starting to wonder if it isn't something to do with a latest Visual Studio update. There are things in there I never use like the advertising crap and Office development integration. MS Office has its own issues, like Office 64 bit not being seen by any other application such as Quicken as an installed email program. Or maybe its a conflict with ReSharper which wants to overtake and 'extend' the Intellisense feature.
Either way, I'm sure its a different manifestation of the same issue: Visual Studio settings are going sideways during normal use.
I just came across this issue in VS 2012, reset window layout was doing nothing.
I extrapolated
%APPDATA%\Application Data\Microsoft\VisualStudio\9.0\windows.prf
to
%appdata%\Microsoft\VisualStudio\11.0\Windows.index
... deleted it and was back in business!
Make sure you close all instances of VS first!
