While doing pair-programming on an React project with Visual Studio Professional 2017, my partner was working on my machine and disabled some debugger option to see less warnings. I want to undo what he did, but he is not available any more, so that's why I am asking here. I remember faintly that he said something about disabling "some breaking".
I am sure it must be somewhere in the options window which appears after Debug > Options and on that popup somewhere under the entry Debugging. I attached a screenshot of Debugging > General. I already tried the toggling the 3rd check-box, but that did not do the trick.
The interesting thing is that in the sub-window Output I used to see all those exceptions logged, but I do not see them anymore.

My system got shut down anyhow and after this I am not able to open projects in visual studio 2013. I tried creating new project and it was opening and running fine untill I added a new class library to it. Once my new solution has two project, it started creating same problem. Visual studio is not opening solution with message "Microsoft Visual Studio 2013 has stopped working". I tried to debug this and getting below error:
"System.InvalidOperationException was unhandled
Message: An unhandled exception of type 'System.InvalidOperationException' occurred in Microsoft.VisualStudio.Editor.Implementation.dll
Additional information: Attempting to activate an adapter in state TextViewInitializing"
I tried google to search the solution but not getting anything relevant. I tried clearing temp files but no success. I cleared bin and debug folder but still no luck. Do you have any solution for this.
TFS Error
Error Description: exception has been thrown by the target of an invocation
When I am opening TFS in Visual Studio 2013
I cannot checkin the files also due to this.
First make sure you have run VS with Administrator. And if you have some extensions installed, you can disable them first then do the check in action again.
More ways please refer the similarly question "Exception has been thrown by the target of an invocation." when building a Visual Studio 2010 VSPackage
If above is still not work, you can also try to delete tfs and vs cache (Note: back up your pending changes first).
I have a fresh install of VS2015 on windows 8 and intellisense doesn't work at all (nothing!) in any environment.
I also have VS2013 (with Resharper 8)on the same machine which works fine.
Any ideas before I go through a re-install?
Probably the problem is with ReSharper, I'm running VS2013 and VS2015 on the same machine without any issues.
I would try:
In Visual Studio 2015, go to 'Tools | Options | Text Editor | C# | General both "Auto list members" and "Parameter information" should be checked.
If that doesn't work I would try to disable ReSharper in VS2013 and try to get the normal intellisense working. Same procedure as above if ReSharper fails to restore the settings.
Note: Only do this as a last resort, because it will reset virtually all of your user preferences, including where your toolbars are, environment fonts etc.
I reached here because my intellisense was giving 1000's of errors in the Error List after installing Visual Studio 2015 on a clean Windows 7 machine.
The answers here did not apply to me, but this answer on StackOverflow: Razor intellisense not working in VS 2015, worked for me.
Run this command from the VS "IDE" folder:
devenv.exe /resetuserdata
When I restarted Visual Studio it took several minutes to "prepare Visual Studio 2015 for the first time", and when I reloaded the project all the intellisense errors had gone.
For info, this is how I navigate to the command prompt:
Right-click the Visual Studio 2015 shortcut on the start menu to get the context menu:
Select 'Open file location' to open a new Explorer window:
Left-click anywhere on the white to deselect devenv.exe, then shift + right-click to bring up the extended context-menu, then select 'Open command window here':
Then paste the command: devenv.exe /resetuserdata
When Visual Studio starts, it's been reset:
And when I load project, errors are gone:
Make sure Tools -> Options -> Text Editor -> C# -> IntelliSense -> "Show completion list after a character is typed" is checked. I had installed and uninstalled VS 2017 and that's when IntelliSense stopped working in VS 2015 for me.
How I fixed it:
I went to Tools -> Extensions and Updates and uninstalled every extension I wasn't using. There were only about 3 of these. One I remember removing was "Microsoft Office Extensions", or something like that. I don't have either resharper or Xamarin, which I've seen mentioned in relation to this. When I'd finished Visual Studio restarted itself, and XAML intellisense was back! Relief...
It may be the case that all you need to do is uninstall any one extension, and the resetting that VS does after that fixes the problem.
Further detail:
I don't recall changing anything specifically (eg. installing anything), when this problem suddenly appeared. I suspect it was due to a Windows update. I was really worried about this one!
I tried restarting VS, and restarting my PC, several times without success, and also checked my intellisense settings. I tried the suggestion of unchecking them and checking again.
My F# code had also lost intellisense. C# was fine, except for XAML.
It was in all VS2015 projects.
Version: Visual Studio 2015, Windows 10. January 2018.
I might be kind of late for the party, but hopefully this helps out anyone.
Please note, the below is just one possible cause for the issue described in this topic.
Your issue might be that you have one project/library referencing the other, but the Target Frameworks are different.
Make sure the frameworks are compatible and see if intellisense picks up your using references, etc.
Since today I can't debug any applications anymore.
If I want to start the debug session, I get the error message
error while trying to run application: invalid pointer
It doesn't depends on the project, this behaviour appears in every project/solution.
What i've already tried:
Reset VS settings
repair Visual Studio
complete reinstall of visual studio
Changed Build Platform to x86/x64
Enabled native code debugging
If you press Ctrl-F5 to run the application, you won't get the error and the application will start, but you can't do debug, so this isn't a real solution.
The only way to solve the problem is to update Visual Studio: I had the same problem (WPF application), which was solved by the Microsoft Visual Studio 2013 Update 4.
If you're running VS 2013 and get an error that's pointing to the body tag, try adding this to the web.config under
<appSettings>
<add key="PageInspector:ServerCodeMappingSupport" value="Disabled" />
That key disables browser link which currently isn't playing nice.
