Why wont Visual Studio Code show build errors - debugging

So I've been using VScode, and VS for a awhile now but I realized for some odd reason it doesnt seem to want to show me build errors anymore.
Has anyone ever noticed this and found a fix? I tried searching on here; but there were literally 7 VSCode related questions, none of which were applicable to my situation.
I have tried:
Going View > Restart Omni Sharp.
Crtl + Shft + M; to view problems.
I'm don't think I ever downloaded any extensions for this either before.
Current code:
As you can see its not asking to resolve [Required] by adding:
using System.ComponentModel.DataAnnotations;
It used to display a red squiggle, and then you could hover over it or press Ctrl + space / Ctrl + . and it would suggest adding the using statements/imports/etc.
Any help would be appreciated :)

Edit.GoToAll command in Visual Studio does not show file name suggestions

Context
I use this command with the shortcut Ctrl + T (alternatively Ctrl + ,) to quickly navigate to files in my solution (WPF app if relevant). As I do not remember the exact file names I would (until recently) use the suggestions that were showing below the prompt to find my files as in this example:
Navigation with suggestions
Source of example
Since I last started VS I get none:
Navigation without suggestions
Attempts
Restarting and updating visual studio didn't help. Neither did deleting the .vs file of the solution. I also toggled the statement completion fields in Tools > Options > Text Editor > All Languages, saw no change.
I believe this might be some Intellisense error but I am not sure. I would be thankful for any guidance or information.
One possible cause is somehow you had collapsed the list. If you hover over the point in the picture below you should get a resize handle. Grab it and pull it down to get your list back.

CTRL+D is not working in vs code copy similar code

Previous in I have used ctr+d for duplicating the code many times, but when I switched to desktop and installed vs code and all the necessary extensions for my react project. And now this CTRL+D keyboard shortcut is not working. Can any help me to solve this issue
I recently met this issue too. I found a solution, see this: https://linuxpip.org/duplicate-lines-vscode/.
The main step are:
File > Preferences > Keyboard Shortcuts.
type "copy line",then you will see the related shortcuts.
remember the new shortcut(e.g. Shift + Alt + Down) or modify the shortcut to ctrl + D.
shift + alt + arrow-down works for me.
For me it was a VS Code extension causing the ctrl + ... binds not to work. It was "Vim emulation". Try isolating the issue by uninstalling the extensions until you find which one.
Similar issue for Windows 10, resolved using CTRL + F2.

How to enable fix-it on Xcode 4.0?

I just upgraded to Xcode 4, and I was reading a Xcode 4 Transition Guide when I found information about a new feature called Fix-it, which show the erros as I type. I am using C++ (.mm files) and set the compiler to LLVM GCC-4.2, but it is not showing the errors as I type. How can I enable this feature?
They don't show as you type like they say, or at least I haven't been able to get it to show the errors. It just shows you a red circle on the line number that you have to click to get the fix it suggestions. It's pretty lame, but you can use a keyboard shortcut to do the fixing at least. Thankfully they included a "Fix all in scope" key bind too.
Fix Next Issue:
control + Command + '
Fix Previous Issue:
control + Command + "
Fix All In Scope:
control + Command + F
Just tried looking again, and the closest thing I've been able to see about possibly showing errors as you type is to switch to issue navigator and leave that on. Your errors as you type will show up in there, but it is very discrete while in the code view. Then you can just click the issue in the navigator and you'll get your suggestions box, which is nice.

# shows solution navigator instead of typing an #

I can't seem to find a question on this, but it might be because I'm unable to find a good way to search for it...
I recently updated my installation of Visual Studio 2010 Pro Power Tools, and now every time I type # in a code window, I get a search window of some sort opened instead of the # symbol in my code. I can't find the key setting that triggers this, and it's beginning to be a real problem.
I'm on a Swedish keyboard, so to get # I press Alt Gr+2. I've gone through all the settings under Tools/Options/Keyboard that starts with "View.", but found nothing.
Can anybody help me delete this keyboard mapping?
Update: I just realized that the key mapping Alt Gr+2 is equivalent to Ctrl+Alt+2. But I still can't find what it's mapped to...
I found the problem in the comment thread on the VS team blog post on the Solution Navigator - it turns out this problem is built-in into the extension, and they're working on fixing it for the next release. (Basically, they're binding stuff to Ctrl+2 and 2, but VS also takes the Ctrl+Alt equivalents, which then are interpreted as Alt Gr...)
For now, disabling Solution Navigator solves the problem (but, obviously, makes Solution Navigator unavailable...), but hopefully there will be a fix out pretty soon.

Search stops working for "Entire Solution"

Somehow Visual Studio search has stopped working for me. Anytime I search "Entire Solution" for some text I get this result:
Find all "[Whatever I was searching for]", Subfolders, Find Results
1, "Entire Solution" No matching text found to look in. Find was
stopped in progress.
Why does it suddenly say "No files were found to look in"?
I've found a number of links on Google that say to press Ctrl + Break or Ctrl + Scroll Lock, but none of them seem to work for me.
I get that problem once in a while. One seemingly nonsensical solution I've found is to click inside the Find Results window (not the Output window). Once the blinking text cursor is visible, hit Ctrl+Break four or five times. This seems to "unblock" whatever causes the problem.
There are reports Ctrl + ScrLk may need to be used instead of Ctrl+Break . If these doesn't work then try Break alone.
Note from Codeguard: I have found an explanation and deterministic solution to this problem
Windows 7 Pro SP1 64-bit, Visual Studio 9.0.30729.1
Didn't Work:
Ctrl + Break
Ctrl + Scroll Lock
Restart of Visual Studio
Worked:
Break (in Find Result 1 & 2) (only pressed once)

Bug source
This is neither Visual Studio nor Windows related bug. In fact, the bug is in your keyboard! Many keyboards from different vendors have been reported to be buggy.
Problem
If you press Ctrl+Break and release Ctrl first, then Break gets stuck on a buggy keyboard. If you ever pressed Ctrl+Break the "wrong" way, you will have this problem with search being interrupted.
Details
According to scan code specifications, Break and Ctrl+Break are special. They send "make" (press) AND "break" (release) scan codes the moment you press Break. They send nothing when you release Break. The buggy keyboard will send the following sequence:
Ctrl "make" scan code
Ctrl+Break "make" scan code
Ctrl "break" scan code
Pause "break" scan code
That is, Ctrl+Break is never released, but instead Pause is released.
Reproduction
You could for example use old good Spy++ from Visual Studio tools. Attach it to anything, for example Windows notepad, and monitor messages (I suggest that you select only keyboard messages). Press Ctrl+Break, releasing Ctrl first. Check the output from Spy++. You will see the sequence I shown in Details section.
I have tried two different keyboards on the same computer. Logitech K120 has the bug while some other Mitsumi keyboard behaves according to specifications and does not have the bug.
If you think about it, it's easy to understand that correct behavior needs special case handling, while buggy behavior is naive. This is why many different keyboards can be buggy.
Solution
Replace your keyboard :)
Workaround
You simply need to press Ctrl+Break, paying attention to releasing Break first. It doesn't matter which application is active.
This bug has been in Visual Studio a long time and it never seems to get fixed.
See this MS Connect item from 2004: http://connect.microsoft.com/VisualStudio/feedback/details/105511/find-in-files-says-no-files-were-found-to-look-in-find-was-stopped
I couldn't believe they still hadn't fixed it in VS2010 - but it's still there :(
The Connect item has been marked as Closed - Won't Fix: https://connect.microsoft.com/VisualStudio/feedback/details/718217/find-was-stopped-in-progress-while-performing-search-in-visual-studio
Ctrl+Break or Ctrl+ScrLk cancel a find operation. Try it. What has happened is that some software layer (presumably Windows) thinks those keys are still being pressed even though they are not. Pressing and releasing them clears the flag.
It could be any of these combinations:
Ctrl+Break
Alt+Break
Break
Ctrl+ScrLk
Remember that you have multiple control and alt keys on your keyboard -- try it with each of them. If it's the right Ctrl key + ScrLk, pressing the left Ctrl is not going to resolve the issue.
Here is the Connect issue which Microsoft closed as "Won't Fix".
If this is a recurring problem for you, there is a Visual Studio extension that suppresses the virtual key that causes the problem.
Ctrl + F and Ctrl + Shift + F have stopped working on Visual Studio 2015 Community Edition.
My friend told me going to:
Tools → Import and Export Settings:
Choose: Reset all settings → Next
Choose: No, just reset settings, overwriting my current settings → Next
Choose: General → Finish
In my case I had a bogus character in the "Look at these file types:" field in the search window.
Removing the character solved the problem.
Visual Studio 2017
Search solution in Visual Studio 2012 is broke. I tested this on three machines, did not work on two. What I found which does work is click on drop down arrow next to search field and select Find all. This is a bit of pain because you have to select drop down every time you search in solution.
I tried all the previous options. They didn't work for me, but reading them made me sure that this is a bug, and I will have to try some unknown ways to get it working. So, I tried a simple file search in Visual Studio 2010 in:
The current document
All the open documents
Both of which worked.
Then I tried Find in Files and woah! It started working.
Unfortunately none of these special key strokes work for me. Only restarting Visual Studio 2010 seems to work for me.
I had the same problem in Visual Studio 2013 (Update 3). None of the key combinations listed previously worked for me. I had *.cs selected in the FileTypes.
To get it working, I changed it to *.*, and then back again to *.cs - now it works.
I have been using Visual Studio 13 without this problem for couple of years now and I started having this issue after applying Update 5 or it could be a weird keys combo pressed by me unknowingly which triggered it, I don't know for sure.
Echelon_Force's solution worked for me. Thanks!
Didn't Work:
Ctrl + Break
Ctrl + Scroll Lock
Worked:
Break (in Find Result 1 & 2 window - Only pressed once)
Happy finding in files!
All of the combinations of Scroll Lock and Break didn't do anything for me. As a workaround, I added the solution directory to the Search Folders (the second ellipsis button), then changed the Look In field to the solution directory. The root problem still exists, but for me, this is functionally the same thing.
(Visual Studio 2013, Windows 8.1, x64)
I was using Visual Studio 2022 (tried with both professional and community, V 17.2.5), my search function was not working in Find in All Files, so I browsed to my solution folder, under .vs\{ProjectName} folder, there is another folder with name FileContentIndex. After closing visual studio and deleting this folder, and restarting vs, seemed to solve my problems, and my Find in All Files started functioning correctly.
I had the same problem as glenneroo today, after updating Visual Studio 2019 to 16.4.3. Found a solution that worked for me here.
Open Find Options and check if there is a (special) character in the Look at these file types text field. If so, remove it.
In Visual Studio 2013 after Update 3, I had the same problem. Before, I could just put ".cs" or ".cshtml" in the Look at these file types: and it would work. But after Update 3 I now have to put ".cs" or ".cshtml" (or whatever file types I want to search in) and it works fine.
This works for me after everything else didn't or worked only sometimes:
Do the search, and while searching, hold CRTL all the time and keep pressing Break.
If you are searching for multiple file types, they must be separated with a ; character, not a space.
This returns the correct results:
*.cs;*.vb;*.js;*.aspx
This returns nothing at all:
*.cs *.vb *.js *.aspx
This isn't the problem the original poster, but for other people who can't figure out why their search isn't working, this could be the reason.
Another late-to-the-party answer, but I found yet another "solution" for this problem.
When it looks as if the Visual Studio app has frozen on search...leave it alone. Don't close it. Don't restart it. Just let it go for about 10-15 minutes and the problem may correct itself, as it did in my specific case. I'm not sure as to why leaving it alone solved the problem, although my wholly uneducated guess is that Visual Studio is building some sort of an index to be able to search files and running into a snag. Once the 10-15 minutes are up and VS completes its search, it seems fine after that.
Probably won't apply to most situations, but what fixed it for me was turning off 'Use Regular Expressions' in the search window. I had previously been using Regular Expressions for some tricky replacements and didn't turn off when finished. I think perhaps it was interpreting part of simple replace text (see below - had some special characters) as the start of an incomplete or malformed regular expression, and so couldn't actually do any matching. Would be nice if it told you!
It only seems to lock-up if I use Ctrl + F (Find in Entire Solution) and never if I use Ctrl + Shift + F (Find in Files).
That Ctrl+Break trick worked for me for years, it's really interesting to finally understand why this happens. With VS2015 I have somewhat related problem with search: my Ctrl+Shift+F simply does not work, this key combination seems to be ignored when I press it. I tried to reinstall even VS 2015 and I still got that same broken behavior.
In case somebody has identical problem, here's what was the reason:
I turns out that for whatever random reason VS2015 shows that "find in files" dialog on another monitor that's attached to my PC. That other monitor is 4K Samsung TV that normally stays "Off" and I have no clue why VS 2015 sends that search dialog box to that monitor. Surprisingly, when I turn on my TV the search dialog moves to the primary monitor on its own!
Ctrl + Break works for Visual Studio 2008
Nothing worked for me. I use also Resharper. So I had to reset my VS key bindings and reapply Resharper shortcuts. Only this got me it working.
Reset current keyboard configuration (Tools | Options | Environment | Keyboard | Reset).
Go to ReSharper | Options | Environment | Keyboard & Menus | "Visual Studio" | Apply Scheme.
I am running Visual Studio 2012 Professional in a Virtual Machine, connecting using rdesktop from a Linux machine.
None of the other suggestions worked, but solved the problem was:
Go to the 'Find and Replace' screen. (ctrl-shift-f in my case)
Enter a search text and choose 'Entire Solution'
Hit 'Find Next', it should find a result.
Hit 'Find All', now works without aborting. (Note, i hit my Mouse really hard and some swearing was involved, too, but I don't think that has any relevance apart from a psychological one :D )
Tried all the solution, but the fixed of mine was I accidently change to another language keyboard on my windows, after I change back to English keyboard, it work, finally I can ctrl + shirt + f
I'm currently using VS2019 16.7.7, and, if I try to find something in the whole solution, VS never finds all the occurrences, sometimes only one, or none.
In some recent release of VS2019 (perhaps 16.5 or 16.6) the old "Find and replace" dialog was replaced by a new "Find in files" dialog, and this new one is failing for me. One solution that worked for me was to disable the new "Find in files" and keep using the old "Find and replace" dialog by checking Use previous Find In Files in Tools > Options > Environment > Preview features.
However, I observed that this was only failing in one of my open Visual Studio instances, so I tried the simple "close VS and open it again", enabled the new "Find in files" functionality, and it started working.
Two possible solutions, in case the simple "close and open again" fails.
The following worked for me. Visual Studio → menu Windows → Reset Window Panel. The resizing of Visual Studio made it to hide the option.
This was one of my biggest problems with Visual Studio. For me (Windows 10, Visual Studio 2015) the find in all files window got locked with a white-out, and guess what, hitting print screen solves it.
This has begun occurring for me with the update to Version 15.8.8 of Visual Studio. None of the above steps worked. There is no error. Just what appears to be a 'stuck' search.
I had recently installed ApexSQL Refactor 2018.03.0331. Uninstalling this did not resolve the issue and does not seems to be the cause. It seems to be related to Version 15.8.8 of Visual Studio update.
I completely uninstalled Visual Studio and reinstalled Version 15.8.8 again. The issue with Ctrl-Shift-F searching the Entire Solution is no longer an issue. Whatever caused the problem does resolve after uninstalling and installing.
I once again installed ApexSQL Refactor 2018.03.0331 and everything still works well.
