Intellisense not automatically working VSCode
C#Visual Studio-CodeC# Problem Overview
I just downloaded Visual Studio Code and my Intellisense is not automatically working.
The two settings that control this seem to be set correctly:
"editor.quickSuggestions": true,
"editor.suggestOnTriggerCharacters": true,
I do get an Intellisense menu when i start typing and press "CTRL + Space", but this gives me a list of everything and not things specifically for my object.
What am i doing wrong?
C# Solutions
Solution 1 - C#
Visual Studio Code's more advanced editing features (IntelliSense, refactoring tools, etc.) only work in C# files if you have a project.json
file or *.sln
file that VSCode is aware of. Open the folder (i.e. open the File menu and click Open Folder...) with the *.sln
file or project.json
and VSCode will attempt to find all project/solution files in the folder. If there are multiple projects, you may need to select one from the projects button on the right side of the status bar (bottom of the window).
From the VSCode website:
> - Selecting a project.json
-file is opening a DNX-project and VSCode will load that project plus the referenced projects
- Selecting a
*.sln
-file is opening a MSBuild-project. It will load the referenced*.csproj
-projects and sibling or descendantproject.json
-files but no other project files that are referenced from the solution file. - Selecting a
folder
will make VSCode scan for*.sln
andproject.json
files and VSCode will attempt to load them all.
Solution 2 - C#
If you have a workspace and for some reason have multiple folders you may need to 'help' omnisharp a bit. I initially had a big project and added a solution for it further on - ending up with TWO workspace folders (one to a startup project and one to the solution). After composing that setup I experienced only the first project to have intellisense working.
Solution to get intellisense working was to make sure omnisharp worked its way from the solution instead of the project:
- Ctrl + Shift + p
- Write "OmniSharp: Select Project" and press Enter.
- Choose the solution workspace entry.
Inspiration gotten from 'swaner': https://github.com/OmniSharp/omnisharp-vscode/issues/1889
Solution 3 - C#
If you are start your project with c#, then some time you haven't download extension.
Process by written
- Ctrl + Shift + p.
- Write "OmniSharp: Select Project" and press Enter.
- Choose the solution workspace entry.
- Then enable the c# extension for "OmniSharp : Project".

Solution 4 - C#
As of the 0.5 version I have found that I need to close and re-open my working files to get some new intellisense information to start working for my own files. This usually happens after I have a file open that needs to use type information from another file I just created. Until I close and re-open them (within the editor) the intellisense doesn't always work.
Hopefully this is something that'll get fixed as the app matures.
Solution 5 - C#
Downgrading to 1.23.9
of the C# VS Code extension fixed the intellisense for me. So if nothing else is working for you, perhaps try installing an older version of the extension (doesn't necessarily have to be that exact one I mentioned). You can do this by selecting this option in VS Code:
Solution 6 - C#
Inorder to make the intelligence working, the Visual Studio Code extension OmniSharp should be there along with Mono. When you open a project/solution folder, the OmniSharp gets the project dependencies from either project.json or from the dotnet solution file (if the project/solution created with other versions of visual studio).
So, when you look at the omnisharp's output window after immediately opening the project/ solution folder, you may see the following lines
Starting OmniSharp server at 2017-9-18 09:26:44
Target: /Users/{username}/Source/{Your Solution Folder}/{Your Solution
file}.sln
OmniSharp server started wth Mono
Path: /Users/{username}/.vscode/extensions/ms-vscode.csharp-1.12.1/.omnisharp/run
PID: 5808
post that, you may see couple of lines coming up like below,
[info]: OmniSharp.MSBuild.MSBuildProjectSystem
Update project: {Your Project1 Name}
[info]: OmniSharp.MSBuild.MSBuildProjectSystem
Update project: {Your Project2 Name}
....
they mean that your projects are getting recognised by OmniSharp Extension.
If you get any error message informing you about timeout, please get into the settings of the Visual Studio Code, and add a configuration override like the one below:
"omnisharp.projectLoadTimeout": 200
I know it is too long to wait for 200 seconds. But don't worry, this won't stop you anymore working with project files. But, remember that the IntelliSense will be automatically available once all the projects in the folder are successfully loaded.
Feel free to extend the Timeout setting since it will help you getting intellisense even-though you are not getting it immediately.

Hope my information helps you! Enjoy your VSCode!

This case was for an existing project that was working fine before. Opened via the vs code "recent" history.
For dotnet core. I opened my project's *.csprog file, made no changes, and saved it via the vs code editor.
As soon as I saved, all of the intellisense stuff starting working again in my other files within that project.
Solution 8 - C#
Another troubleshooting strategy to try if none of the above works out is uninstalling Mono, which is unnecessary anyways if you're using .NET Core. I also experienced a sudden disappearance of Intellisense after pulling changes to one of our enterprise repos that included an upgrade from ASP.NET Core 2.0 to 2.1. Strangely, at the same time, Intellisense was working fine in another C# project repo running ASP.NET Core 2.2.
For the project in question, I was puzzled to see successful logs for each reboot of the Omnisharp server as well as perfectly clean builds and runs. The puzzlement increased as I compared these Omnisharp logs to those from the 2.2 project and found them effectively identical.
Upon uninstalling Mono, the one detail that changed is how Omnisharp started. Now it boots up from a shell script located at ~/.vscode/extensions/ms-vscode.csharp-1.19.0/.omnisharp/1.32.18/run
. Previously, Mono itself was booting the server from the executable at ~/.vscode/extensions/ms-vscode.csharp-1.19.0/.omnisharp/1.32.18/omnisharp/Omnisharp.exe
.
Other troubleshooting I attempted in this instance though to no avail:
dotnet clean
/ Deleting bin and obj directories- Updating
launch.json
to point at the proper/bin/Debug/netcoreapp2.1
build directory - Wiping my local nuget cache
- Restarting Omnisharp
- Uninstalling and reinstalling VS Code, as well as bumping back a version from 1.33.1 as the breakage coincided oddly with the March 2019 update
- Uninstalling and reinstalling the C# VS Code extension, as well as bumping back a version from 1.19.0 given other users' reports of said version interfering with Intellisense for certain projects*
- Adding a
global.json
file at project root to override default utilization of latest .NET Core SDK (mine was 2.2.105) and run instead using 2.1.302 in concert with the project's version - Wiping/rebuilding the project
.sln
file
Specs: VS Code 1.33.1, C# Extension 1.19.0, MacOS High Sierra 10.13.6.
*NB: As it turns out, in another .NET Core 2.1 project with the same issues in VS Code as described above, uninstalling Mono alone did not fix things. I also did wind up needing to bump back the C# extension to v. 1.18.0 to recover Intellisense. Weird.
Solution 9 - C#
The issue I had was OmniSharp
was an older version. I set the flag to update to latest version in Settings.json
file. This ensures the extension is always the latest version.
"omnisharp.path": "latest"
And restarted VS code. That fixed it for me.
Solution 10 - C#
I've had some good experiences in C# with this extension so far: https://marketplace.visualstudio.com/items?itemName=jchannon.csharpextensions
"This extension traverses up the folder tree to find the project.json or *.csproj and uses that as the parent folder to determine namespaces."
Solution 11 - C#
Simply reinstall the extension and restart the VSCode/PC.
Solution 12 - C#
I use Task Manager
and kill the Visual Studio Code process
, then restart Visual Studio Code
, the intellisense shows and fixed.
Solution 13 - C#
Try "Install Extension" from command Pallete - probably if C# intellisense is not there:
Solution 14 - C#
if intellisense in not working for react js or javascript or node js this solution will help for windows
- uninistall type script by typing
npm uninstall -g typescript
- install specific version of type script that is 3.3 by typing
npm install -g [email protected]
- add the typescript location in vscode by navigating to file > Preferences > settings > here search for
edit in setting.json
then add this path"typescript.tsdk": "/Users/yourusename/AppData/Roaming/npm/node_modules/typescript/lib"
- settings.json should look someting like this
> > { > > "editor.suggestSelection": "first", > "vsintellicode.modify.editor.suggestSelection":"automaticallyOverrodeDefaultValue", > > "typescript.tsdk": "/Users/yourusername/AppData/Roaming/npm/node_modules/typescript/lib" > > }
Solution 15 - C#
I was able to fix this by changing the Api Compatibility Level from .Net Standard 2.0 to .NT 4.x. You can find this setting on Project Settings / Player. After that, intellisense started working again.
Solution 16 - C#
This is because of C# extension issue. Reinstall the extension will work.

Solution 17 - C#
I fixed this with a multiple project solution in .net5 / .net core 3.1 by opening each project (not the sln folder) in VSCODE. This then prompts to add the resources/ .CSX? files to the project; enabling intellisense, per project. Finally close that window and reopen the solution folder and all works as expected.

Solution 18 - C#
After trying several things I looked at the OmniSharp logs only to realize that because I had two different sln files in my workspace. It had picked up the “other” one and thus wasn’t working. I deleted it, reopened vs code, and all is well again.
Solution 19 - C#
For me I had been working without internet for a long time. It had previously been working but then stopped. I closed+reopened VSCode with a stable wifi connection and the Output
tab in VSCode popped up, displaying the the extensions were re-installing. After that it worked!
Solution 20 - C#
in my case , the extension wasn't enabled
Solution 21 - C#
I just had this happen (this being no code completion suggestions appearing). What resolved it for me was changing the VSCode Editor package in Unity to a previous version and then back to the current version.
For me, this was going from 1.2.0 to 1.1.3 and then back to 1.2.0. I believe removing and reinstalling 1.2.0 would have accomplished the same.

I know this is probably the most obvious answer. But I had enough dealing with VS Code ridiculous bugs. You should be focusing on code, not the buggy IDE. Their documentation doesn't make it easy either to debug.
Steps for complete uninstallation:
- Save your personalization files such as
keybindings.json
,
Just put it on GitHub or something so whenever you need have trouble with VS Code you simply just need to go to GitHub and copy-paste it.
- Uninstall VS Code completely
When you uninstalled VS Code, it doesn't erase your extension files and some old settings. This is the cause of the re-installation ended up the same. Horrible move VS Code. For the list of the files that you must delete, you can check out this answer.
- Go to their website and install the new one.
I hope this helps some people who are already had enough with the VS Code ridiculous bug.
Solution 23 - C#
In my case, the issue was not with VS Code settings. The error was due to a corrupted TEMP path configured in my PC's registry user profile environment settings. I got this error from Help --> Toggle Developer Tools --> Console The error was flagged in the console when I opened a new typescript file.
Unable to write file c:\Users\XXX\AppData\Local\Temp;C:\wamp64\bin\php\php5.6.25;C:\vufind-3.1.2\install.php\09cf49d8-af5b-42e9-8194-43f5b566be0f'
Obviously this path was corrupted. After updating the environment variables in registry settings, the VS code IntelliSense started working. Checking the console is a good start to find the root cause of this issue.

Earlier intellisense was working for Angular
in VS-Code
but for some reason (which I don't know) intellisense stopped working. I had extensions installed i.e. Angular Essentials
and Angular Language Service
etc. that were responsible for this intellisense and all that.
What I did?
I disabled the extensions
, restarted VS Code
and enabled them. It was all working fine as before.
Solution 25 - C#
If everything in VSCode is working ( No errors in output console, language server is working etc.) and built-in extensions are enabled. Still, if your IntelliSense is not working for normal .js
files make sure variables are defined with a type identifier such as var d = new Date()
or let d = new Date()
. In my case, IntelliSense was not working for d = new Date() (No autocomplete for Date object 'd' APIs in this way)
but started working fine when I specified a type before my variable names.
Solution 26 - C#
Download and install "Tool for Visual Studio 2019" as the C# extension under hood use the build tools: https://visualstudio.microsoft.com/downloads/
Solution 27 - C#
In my case, I had an extension installed (Explorer Exclude) to help me focus and hide certain files that I don't regularly work with within the Explorer.
I so happened to have disabled viewing *.sln, *.csproj and *.vsconfig files and folders, which apparently prevents VSCode from even knowing the file is there in the first place. Disabling these specific rules solved the problem instantly.
Took me ages to figure out... The more you know.
Solution 28 - C#
I solved it by uninstalling all SDK's (not sure if this is needed) and installed 4.7.1 developer pack
win 10, vscode 1.63.2, unity 2020.3.25f1
Solution 29 - C#
I fixed this by installing .NET Framework 4.7.1 Developer Pack:

Clearing typescript cache and downgrading the typescript version to 3.3 solved the issue for me.
Follow these steps to clear cache and downgrade typescript version:
- Enter following command in terminal according to your OS and delete whatever is inside it.
- Mac:
~/Library/Caches/TypeScript/
- Windows:
%LOCALAPPDATA%\Microsoft\TypeScript\
(windows users can run this in run box too) - Linux:
~/.cache/typescript/
- Install this specific

using following command.
npm install -g [email protected]
- Restart VSCode.
