Intellisense not working for Visual Studio Code

Operating System: Windows 10

Problem:
1. Intellisense and Autocomplete not working for VScode.
2. Opening c# script within the editor opens VSCode. However, VScode Doesn't automatically open a project folder.

Programs and program versions: Unity 2019.18f1, VSCode 14.1

VSCode Extensions:
1. c#
2. Visual Studio Intellisense
3. Unity Debugger
4. Unity Tools

Attempted solutions:
1. Tested with .Net 4.6.x, .Net 4.7.x, .Net 4.8.x and same results
2. Fully uninstalled and reinstalled VSCode as well as Unity. Same results.
3. Followed this guide but no change.
4. Instead of selecting the Visual Studio Code in External tools I attempted to open the code.exe file directly, no changes.
Any Help to fix these problems would be great.
Thanks.

 

Same here!

 

I believe it's due to updating the debugger, and pointing to a new C#/Omnisharp VS code extension. I have a workaround here:
https://forum.unity.com/threads/psa-if-your-vs-code-c-extension-stopped-working.841255/

 

Any solutions?

 

Same. Hate it.

 

You need visual studio code from package manager. I wish this is included with Unity.

 

Bro, i have the answer for you. the solution is super SIMPLE
you just have to download this tool
- Unity Code Snippets by Kleber Silva
which you can find it on VSCode, after installing it, close the VSCode and reopen.
That's it.

I've been strolling to any possible solutions I could find for the same problems as yours, but the answer is just as away as your right-hand to your mouse.

 

I found a fix for this in VSCode and it's only a few steps.

Your environment in VSCode may vary, but I have all the extensions you have in the OP.

But here's what I experience. I make a new project, after OmniSharp loads in VSCode. The packages don't highlight correctly, and I don't have intellisense. So I do the following:

1. Go to Unity -> Edit -> Preferences -> External Tools
2. Look for the section near the top called "Generate .csproj files for:" and click "Regenerate Project Files" with everything unchecked.
3. Then in VSCode I press "Ctrl + Shift + P" and run the action for "Developer: Reload Window"

Intellisense and all your other syntax highlighting should start working again.

I hope this works for y'all. I am on Unity 2019.3.13f1

EDIT: Removed the step to delete the Assembly-CSharp.csproj file. Regenerating it in step 2 is enough.

 

I was also stumbled upon the same problem recently.

The problem with me was that in *.csproj file it was referencing to the .net framework v4.7.1 so I simply edit the *.csproj file to v4.8 and all the intellisense were back.

 

Sometimes I have this issue, also. Consider upgrading Visual Studio Code package to 1.2.0 and if omnisharp doesn't work, right click to anyplace in assets and click Open C# Project.

 

Install .NET core sdk and restart your PC. It worked for me.
download here:
https://dotnet.microsoft.com/download

 

Thank you sooo much, i've try different solution but that's the only one that worked for me!

 

Thank you very much this worked for me. Before I did this classes like "Rigidbody", "Animation", etc. were not showing so thank you very much!

 

Hey guys, my VSCode refuses to run Intellisense, I've tried absolutely everything and I am stuck. Kindly let me know what files and logs you need to see to help. I've restarted my computer, implemented all the fixes on this thread, but nothing has worked.

EDIT: I have a Windows 10 64-bit PC, running Unity 2019.3.14f1, .NET Framework 4.8.0, .NET Core SDK version 3.1.300, Visual Studio Code version 1.45.1, C# extension version 1.22.0

 

I think I can help. On Windows 10 64-bit, Unity 2019.3.15f1 requires the 4.7.1 .NET Framework. You can see this in the error log:

The reference assemblies for framework ".NETFramework,Version=v4.7.1" were not found

Since VS Code is a text editor, it needs to have the framework locally install; having Unity open it isn't good enough. So, I needed to download the .Net Framework, version 4.7.1!

So basically, I downloaded this and now I have Intellisense:
https://dotnet.microsoft.com/download/dotnet-framework/net471

P.S. You might have to restart Unity, VS Code, and your laptop.

 

That's worked for me, thanks bro

 

Going to go try this now. Thanks for the quick response! I'll let you know how it goes.

Cheers!

 

@dan_unity868 it worked! I combined it with a fix which said it might be a dual drive problem (my .NET stuff was on C:\ but VSCode was on D:\) Thanks a ton for your time! Good luck!

 

Worked for me, thanks!

 

isso funcionou para min!

 

Thank you very much. It worked for me.
I had

Code (CSharp):

1. Assembly-CSharp.csproj ... <TargetFrameworkVersion>v4.7.1</TargetFrameworkVersion>

But when checking in installed programs, I had 4.6 version in the laptop. So, I closed VS code, removed 4.6 version, installed 4.8 and changed it in *.csproj file

Code (CSharp):

1. <TargetFrameworkVersion>v4.8</TargetFrameworkVersion>

4.8 version link: https://dotnet.microsoft.com/downlo...nk-you/net48-developer-pack-offline-installer

 

For me, it was that I was missing a certain .NET SDK version. Check the output.

 

Thanks so much. Been trying to work this out for ages. It was a perfect fix.

 

Thank you so much!! Everything works great now!

 

How do you do this??

 

I just used Visual Studio 2017 and when opened the script asked me to use .NET framework version 4.6.1 and just accepted. Intellisense worked just fine. I would love to use VS Code since its lighter but whatever

 

Thanks so much, it's working

 

This worked for me

 

This worked perfectly!

 

I have the new version of unity but in visual studio the transform is not coming. I have spent the last 2.5 hours on google tring many things. I have deleted all extensions and reload them I have selected VSCode directly in unity external tools. All I seem to get is the onClass intellisense. The Transform, GameObjects ect is not coming up. Even tried all the options in this string.

I have the Unity Tools installed the current version of C# and Unity Snippets by Kleber Silva, Which seems the preferred extension. Can someone help or point in right direction.

 

I got visual studio code to work after following:

https://code.visualstudio.com/docs/other/unity

and then installing the .net framework (4.7.1 for Unity 2019.4 LTS) (Omnisharp on visual studio code had an error about missing framework)

https://docs.microsoft.com/en-us/dotnet/framework/install/guide-for-developers

 

Thanks, this worked for me!

 

This one is genious!

 

This is worked for me. Thanks.

Remember you also need to install OmniSharp (C#) add-on in VS Code. If you haven't installed it yet, install it first.

I thought I solved the problem on Mac OS by re-installing the latest MONO, and then following the steps mentioned above: Regenerate projects files within Unity, and then restart VS Code.

It went OK for a few weeks, BUT today I started a new project and now all of a sudden the problem is back, and repeating the above steps doesn't fix it...

The assemblies for .NET 4.7.1 can't be found.... sigh...

How to solve this permanently?

 

To me I fixed this by browsing the Visual Studio Code editor in the Window/Preferences/External Tools-External Script Editor (do not select the Visual Studio Code in the dropdown menu. You must browse it)

The Visual Studio Code executable can be found at "C:\users\{username}\AppData\Local\Programs\Microsoft VS Code\Code.exe" on Windows by default.

It took me for like more than 4hours non-stop just to have a hunch that the problem is caused by selecting the Visual Studio Code from the dropdown menu HAHAHAHA

 

found a fix from another forum, worked like a charm:

In Visual Studio Code, go to the Extension settings for C# Extension (just click on the cog icon), look for "Omnisharp: Use Global Mono" and change the value to "always"

 

Thanks! Fixed it for me too. I just had to relaunch VS Code in the end for it to work.

 

Hello,
I resolved this issue by downgrading the "C# for Visual Studio Code" to the 1.23.0 version instead of the 1.23.2. It began to fail when I upgraded this extension.
Click on the extension's cog and select "Install an other version..."

And the completion, Intellisense came back.

I'm on a MacBook Pro.

 

You are a lifesaver. This worked perfectly for me, thanks a lot!

Mac OS Catalina and Unity 2019.4.3f1

 

Here's a solution where you don't have to downgrade your C# extension:

- go to your settings with control + , (comma)
- set omnisharp.useGlobalMono to "always"

If it's not working, try regenerating your project files.

This should really be detailed somewhere officially as it's a pretty annoying issue that will probably affect a lot of people.

I found this by taking a peek at the C# extension's changelog, where they give you this fun little tidbit:

I'm gonna write this down in case someone still has problems.

If you followed the guide from the official vscode site you will at some point download a .net targeting gimmick to make the autocompletition work.
Except that it won't work, for all the reasons in this thread... and another one.

The .net targeting thing you downloaded is of the wrong version.
The vscode guide made you download the 4.6 when you actually needed the 4.7.

Download this 4.7.1 version: https://www.microsoft.com/en-us/download/details.aspx?id=56119
and if you followed the steps of this thread it will probably work.

 

I found a solution for myself. Unity sets the wrong TargetFrameworkVersion in Assembly-CSharp.csproj. Change it to your version of .NET Framework. When you have changed the value, just reload VS Code, easy way Ctrl+Shift+P Developer Reload. Unity seems to reset the value on Assets->Open C# project.

My working version is 4.6.1 which I found through Visual Studio(it gave me a warning about version discrepancy when opening *.csproj)

The weird thing is that registry Editor says that I have .NET Framework version 4.8.0 but I cannot get that to work.

 

Thank you!!!!!!!!!!!!!!!!!!

 

Works

 

It works! Thank you!!!

 

Worked too, thanks man

 

Thank you so much, this fix worked for me! I had the same ".NETFramework,Version= v4.7.1 not found " showing up in error log, so I installed it from the link that you've given and it worked perfectly after installing it.

I had initially installed .Net Framework version 5.0 which is the latest version, but for some reason intellisense wasn't working. Installing .Net v4.7.1 fixed this issue.

 

Thank you! This was the only thing that worked. There has to be a better way than manually editing the file though. smh.

Edit: There is, just uninstalled the 5.1 or whatever .net core, and installed the v4.7.1 version instead because that seems to be all Unity exports and that seems to do the trick. Thank you for all the help thread.
