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?
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
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 descendant project.json-files but no other project files that are referenced from the solution file.
Selecting a folder will make VSCode scan for *.sln and project.json files and VSCode will attempt to load them all.
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".
Process by image
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:
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.
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.
Here is another link with the same solution: https://github.com/OmniSharp/omnisharp-vscode/issues/1585
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.
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.
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.
Simply reinstall the extension and restart the VSCode/PC.
I use Task Manager and kill the Visual Studio Code process, then restart Visual Studio Code, the intellisense shows and fixed.
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.
Try "Install Extension" from command Pallete - probably if C# intellisense is not there:
https://code.visualstudio.com/docs/customization/colorizer
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 typescript#3.3
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"
}
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.
This is because of C# extension issue.
Reinstall the extension will work.
https://code.visualstudio.com/docs/editor/intellisense
https://marketplace.visualstudio.com/items?itemName=ms-dotnettools.csharp
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.

Downgrading to 1.23.9 of C# for Visual Studio Code (powered by OmniSharp).
https://i.stack.imgur.com/VrdJl.png
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.
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!
in my case , the extension wasn't enabled
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.
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.
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.
Download and install "Tool for Visual Studio 2019" as the C# extension under hood use the build tools: https://visualstudio.microsoft.com/downloads/
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.
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
I fixed this by installing .NET Framework 4.7.1 Developer Pack:
https://dotnet.microsoft.com/en-us/download/dotnet-framework/net471
so I've been trying to get Visual Studio Code set up to work with Unity.
Here is the list of extensions I have for Unity:
C# version 1.21.17
Debugger for Unity version 2.7.5
Unity Tools version 1.2.3
Unity Code Snippets version 1.3.0
So I have the IntelliSense working for methods like Awake, Start, OnCollisionEnter2D etc., but when I try to get methods like GetComponent they dont show up, which can be quite bothering as I am trying to learn and still dont know thte methods so well as to know all of their parameters and the exact way they are named.
So as it turns out(For some reason), the problem was that even though it appeared that when double clicking a script in Unity opened up the entire project folder in VS Code, I could see all the files and that stuff for some reason that was not properly loaded. I tried reopening the project folder from VS Code, rather than from unity and it all worked out. Now I am able to use IntelliSense to its full extent. Leaving this in case others are struggling with this.
Once you've opened up the project folder from vs code, if you leave it open, double clicking scripts from unity will work fine, no need to manually open thtem from vs code everytime you want to edit a script.
Sometimes it happens if you don't set VSCode as the default editor for Unity scripts.
In Unity go to Edit > Preferences > External Tools > External script editor and choose Visual Studio Code.
I am using Visual Studio Code and I have already loaded C# OMNISharp plugin to my system and it works all fine in my existing project/solutions.
However, I just created a new solution and a new project in Visual Studio code and it sounds like for this particular solution, the Intellisense or any other Omnisharp features are just not working. I have tried following things:
Restarting Visual Studio Code
Disabling and enabling my OmniSharp Plug-in
Also, one thing that I noticed is that when a solution is created in Visual studio, it has a lot of code which looks like following:
Project("{2150E333-8FDC-42A3-9474-1A3956D46DE8}") = "src", "src", "{AEA16303-6991-4FF1-A3A9-72D892D7968C}"
EndProject
Basically, these are all project references. However, when a solution is created by Visual Studio Code then there is not any section like that. This solution runs and compiles fine, just that it looks fundamentally different than how a Visual Studio solution looks like.
However, nothing seems to be working. Is there anything that I can try to make it work? Any ideas ?
It's caused by adding *.sln and *.csproj to your "files.exclude" setting.
Try this:
Code -> Preferences -> Settings -> "omnisharp.useMono": true/false
Remove from setting file.
Or, Open your project with MonoDevelop or Visual Studio 2015/2017 first, then reopen VS-Code.
Edit 1: Try setting "omnisharp.useGlobalMono": never and then restarting the omnisharp server.

How did you created the project?
For the Intellisense to work properly the project needs to have a specific structure.
Assuming you have the .net core sdk for mac and the omnisharp extension installed:
Try the following:
Open your integrated terminal (View => Integrated terminal)
Create some new directory to host a test project say "testproj" e.g => mkdir testproj
use the dotnet cli to initialize the project => dotnet new console
See if you got intellisense.
Also i'd recommend watching the .net core on Mac introduction video.
In VS Code v1.43.2 adding following line to settings worked for me:
"omnisharp.useGlobalMono": "never"
The setting's value "never" had to be double-quoted otherwise it would be flagged in red. Even with the quotes, it remained highlighted in yellow. Not sure why, as all other options/values in there are blue. I presume this indicates some sort of warning, but it works.
(As an aside, I would love to understand what a "Globally installed mono" is. However my only interest here was getting IntelliSense working, so re: omnisharp I'm pleading 'newb'.)
This worked for me
"omnisharp.useGlobalMono": "never"
Were your new solution and projects created in a "OneDrive" folder in Windows 10? In latest Windows 10 release, the C# plugin can't start up when a project resides in a OneDrive folder with "File On-Demand" feature on. Please take a look at this issue on Github
I my case, the problem came from the resource folder of my project.
I had added a visual studio .sln file in the ressources to be used as a template but I somehow "variabilized" it with custom tags. OmniSharp tried to parse it and obviously failed, but no error poped up in VSCode, it was only visible in OmniSharp output.
The solution was to rename the template from .sln to .txt to prevent OmniSharp from loading it.
In my case, after installing C# extension, I had to click the setting icon on the extension and then click "Add to workspace recormendations"
I had this problem in 2022 and nothing mentioned above worked for me.
For me the problem was caused by VS Code and C# plugin being updated (in my case c# plugin to v1.25.0+) because in this version they made this:
.NET Framework builds of OmniSharp no longer ship with Mono or the MSBuild tooling (See announcement omnisharp-roslyn#2339). To ensure that the C# > > extension remains usable out of the box for .NET SDK projects, we have > changed the default value of omnisharp.useModernNet to true.
If you still need Unity or .NET Framework support, you can set > omnisharp.useModernNet to false in your VS Code settings and restart OmniSharp.
So entier problem was in omnisharp.useModernNet being set to true by default which renders entire plugin unfunctional but doing what they said and setting
omnisharp.useModernNet to false manually in .vscode > settings.json file solved this problem for me!
For more info, you can also read the entire official VS Code C# Plugin announcement under plugins Details section in VS Code or on this webpage as well!
I'm developing an application (http://sourceforge.net/projects/audiocuesheet/) and use fedora. Since the rpm for fedora is from monodevelop 2.8.x and I need the features of monodevelop 4.0. I downloaded the tarball and build monodevelop. It works good as described, but I can not view the source of my sourcefiles (screenshot).
Has anyone any idea, why this fails? I tried starting monodevelop with no redirection, but couldn't find any error.
It's a known bug.
The only solution (as for now) is to change your GTK theme in KDE settings -> Application Appearance.
They say (the bug has been filed somewhere) it's the problem with the theme itself, but I find it hard to believe... I guess you have oxygen-gtk set, change it to, for example, Raleigh, it will work.
Remember to restart monodevelop ;-)
I like oxygen theme, I find it the most annoying issue with md-4.0..
Edit:
http://mono.1490590.n4.nabble.com/Text-editor-problem-with-monodevelop-4-0-td4658742.html - here is where I've found the solution.
This might by an issue with the oxygen-gtk-theme. See here. Start Monodevelop with the environment variable OXYGEN_DISABLE_INNER_SHADOWS_HACK set to 1.
In the shell:
export OXYGEN_DISABLE_INNER_SHADOWS_HACK=1
monodevelop
You can also put this as a shell script to /usr/local/bin/monodevelop. Then monodevelop is automatically started with this environment variable.
#!/bin/sh
export OXYGEN_DISABLE_INNER_SHADOWS_HACK=1
/usr/bin/monodevelop
Remember to make it executable with sudo chmod a+x /usr/local/bin/monodevelop
