Visual Studio Professional 2013 Crashes When Opening Solutions/Files

Question

I've been trying to open some of the webpage/database solutions I made while working for my previous employer, to get a refresher on what they were, but for some reason Visual Studio Professional 2013 just decides to either crash while opening them, or crash when I try opening one of the C# files I made in them. I have no idea why it's doing this now, since it's been a little over a month since I made these files without any problems. There doesn't seem to be anything wrong with 2013 itself, either. Suggestions?

Answer 1

For VS2013: I've hit a similar problem every now and then and my fix is to delete the *.suo file and then open the solution.

The only time that has not worked was when an extension was playing up, in which case I opened VS in Safemode using the /safemode switch.

devenv.exe /safemode

Using the /log switch as noted in another answer is also a good idea if it turns out to be a misbehaving extension because that can help you track it down. The default location of the ActivityLog.xml file on my computer is "c:\Users\<username>\AppData\Roaming\Microsoft\VisualStudio\<version>\ActivityLog.xml" but you can also specify where you want the file to be:

Devenv /log Path\NameOfLogFile

See the documentation for VS2013 (with links to other versions) at: /Log (devenv.exe)

I hope that helps.

For VS2015: Same solution, just the suo file is in a different place. VS2015 adds a ".vs" folder. Within that folder are other folders, one of which is named the same as your solution, within that folder is another folder named "v14" and within that one (finally) is a file called ".suo". Delete that file.

Example: your solution is called "Whatever". Starting from your "Whatever" folder the path to the suo is:

.vs\SolutionName\v14\.suo

If you can't see the ".suo" file, remember that it is a hidden file.

I've been using this PowerShell script for a few days to get rid of the .suo files after switching between git branches:

get-childitem -Include .suo -Recurse -force | Remove-Item -Force –Recurse

I've not had any problems with it so far, but no promises that it won't incinerate your laptop :) so use it carefully.

For VS2017: The path to the .suo is:

.vs\SolutionName\v15\.suo

My guess is the "v15" will keep incrementing in future releases.

I found another SO answer that covers some other solutions to VS issues, such as flushing the ReSharper cache if you are using that tool: Visual Studio displaying errors even if projects build.

... And VS2019 The path to the .suo is:

.vs\SolutionName\v16\.suo

When I started using VS2019 I got a lot of "errors" reported after a successful build of an existing project. The editor didn't like namespaces from other projects within the solution. Closing VS, deleting the .vs folder and restarting VS fixed it.

Try invoking Visual Studio from the command line.

devenv.exe /log

Then try to open your solution and then if it crashes, go look at the

%APPDATA%\Microsoft\VisualStudio\<version>\ActivityLog.xml 

file. it should have details on the crash. Also, the event logs may capture some high level events as well.
