I want to be Visual Studio Code my default editor for all text-based file types in Windows. For Notepad++ there is an extension in the Windows Explorer to provide "Edit in Notepad++" for each file.
How can I achieve this for "Edit with Visual Studio Code"?
Do I have to "program" such extension on my own or are there any ready-to-use solutions available?
According to this blog post you can set this option during the installation process. If you want to add this option afterwards you either can follow the instructions of the rest of the post or (as recommended) reinstall vscode and then select that option during reinstalling.
When I faced the same issue, for me it was more comfortable to simply reinstall vscode.
It is east !
step 1 -->
Right click the file you want to always open with VS code
example - if you want to always open .txt files in VS code then Right click on any .txt file that is in you system
see this
step 2 -->
click on 'open with'
see this
step 3 -->
click on 'choose another app'
see this
step 4 -->
a new window will open, it will show all the applications on you system that are capable to open that file
click on VS code
and check the box at the bottom that says 'always use this app to open .txt files'
see this
and then click on open
THATS IT
NOW ON .txt FILES WILL BE OPENED IN VS CODE
.txt file extension is just an example, you can do this to any file example .py, .html, .pdf etc.
When I want to edit C# Unity scripts, they open in Visual Studio. It is supposed to provide auto complete for all Unity related code, but it doesn't work.
Here you can see the missing functionality:
As seen, the transform object does not open the autocomplete menu.
Unity version: 5.5.2f1
Visual studio 2015
Visual Studio Tools for Unity is installed
There is no auto-completion because the script says "Miscellaneous Files" instead of the of the name of the Project. Take a look at the image below that came from the video in your question:
The "Miscellaneous Files" message can happen for many reasons:
It can happen when you open your Unity C# file from another folder instead of opening it from Unity Editor.
This can also happen because Unity crashed while Visual Studio is still open therefore corrupting some files.
It can happen because Unity was closed then re-opened but is no longer connected to Visual Studio. When Visual Studio is opened you get "Miscellaneous Files" and no auto-completion.
This can happen when Visual Studio Tools for unity is not installed.
When you create a script from Unity then quickly open it before Unity finish processing it or before the round icon animation stuff finish animating.
Most of the times, restarting Unity and Visual Studio should fix this.
I can't tell which one is causing the problem but I will cover the most likely solution to fix this.
Fix Part 1:
Download and Install Visual Studio Tools for unity from this link. Do this while Unity and Visual Studio are both closed.
From Unity Editor, go to Edit → Preferences... → External Tools. On the External Script Editor drop down menu, change that to Visual Studio 2015.
Fix Part 2:
If newly created C# files are coming up as Miscellaneous then follow the instruction below:
From Visual Studio, go to Tools → Options... → Tools for Unity → Miscellaneous. Under Show connectivity icon, set it to true then restart Visual Studio.
When you re-start, connection icon should now be available in Visual Studio. Click it then choose the Unity instance to connect to. The red 'x' icon should now turn into a brown checkmark icon. Now, when you create a new C# file in Unity, it should open without saying Miscellaneous.
Fix Part 3:
Still not fixed?
Re-import project then open C# Project.
Close Visual Studio.
From Unity, re-import project by going to Assets → Reimport All.
Now, open the project in Visual Studio by going to Assets → Open C# Project. This will reload the project and fix possible solution file problems.
Fix Part 4:
Still not fixed?
Fix each C# file individually.
Click on Show All Files icon.
Select the script that doesn't do auto-complete then right-click and select Include In Project.
Fix Part 5:
Not fixed yet?
Credit goes to chrisvarnz for this particular solution which seems to have worked for multiple people.
Close Visual Studio
Go your project directory and delete all the generated Visual Studio files.
These are the files extensions to delete:
.csproj
.user
.sln
Example:
Let's say that the name of your Project is called Target_Shoot, these are what the files to delete should look like:
Target_Shoot.csproj
Target_Shoot.Editor.csproj
Target_Shoot.Editor.csproj.user
Target_Shoot.Player.csproj
Target_Shoot.Player.csproj.user
Target_Shoot.sln
Do not delete anything else.
Double click on the script again from Unity which should generate new Visual Studio file then open Visual Studio. This may solve your problem.
Fix Part 6:
If not working, check if you are having this error:
The "GetReferenceNearestTargetFrameworkTask" task was not found
Install Nuget PackageManager from here.
Restart Visual Studio.
See this answer for more information.
Fix Part 7
Make sure all of the projects are loaded.
In Solution Explorer it should tell you # of # projects.
If all of the projects are not showing, right click on "Solution (# of # projects)" and click Load Projects.
Try this,
In Unity Editor Go to Menu, Click on Edit -> Preferences -> External Tools -> External Script Editor. Set it to Visual Studio (your installed version of VS).
Now in Menubar go to Edit -> Project Settings -> Player Settings -> Other Settings -> Under Configuration -> Check API Compatibility Level -> Change it to your installed .Net version. In my case I set it to .Net 4.x
Now if Visual Studio is running already go to Visual Studio, it will ask to reload project. Reload the project. Check if it works, if not close Visual Studio. Now Open cs file from Unity Editor, and now it should work.
I found another way to fix this issue in a more convenient manner:
Select the broken file in Solution Explorer.
Open its Properties.
Switch field "Build Action" from "Compile" to "None".
Then switch it back to "Compile".
This will kill the synchronization between Unity and Visual Studio somehow.
The next time Visual Studio will reload the project, it will prompt a warning.
Just click on "Discard".
If you have done all of the above and still isn't working , just try this:
Note: you should have updated VS.
Goto Unity > edit> preference >External tools> external script editor.
Somehow for me I had not selected "visual studio" for external script editor and it was not working. As soon as i selected this and doubled clicked on c# file from unity it started working.
I hope it helps you too.
Unload and reload the project, in Visual Studio:
right click your project in Solution Explorer
select Unload Project
select Reload Project
Fixed!
I found this solution to work the best (easiest), having run into the problem multiple times.

Select project in Visual Studio
Click "Refresh" button
I hit the same issues today using Visual Studio 2017 15.4.5 with Unity 2017.
I was able to fix the issue by right clicking on the project in Visual Studio and changing the target framework from 3.5 to 4.5.
Hope this helps anyone else in a similar scenario.
Two Alternative Options:
Fix 1
#singleton pointed me in this direction. Instead of changing the target in Visual Studio you should change it in Unity since the project is auto-generated.
First delete the auto generated Visual Studio files:
.csproj
.user
.sln
Then from within Unity go to PlayerSettings and under 'Other Settings' change the 'Scripting Runtime Version' from Stable 3.5 to Experimental 4.6.
However, that didn't fix it for me.
Fix 2
I noticed all of the references to Unity related code was marked with a yellow warning. Check your error logs and see if this is the case. In particular see if you get the following error: getreferenceNearestTargetframeworkTask
If so try:
Start Visual Studio Installer again.
On the Build Tools 2017, click Modify,
Ensure that "Nuget targets and build tasks" are ticked. This should become ticked if you click on Universal Windows Platform development.
Update 2020 with Visual Studio Community 2019 and Unity 2019.3:
Open Visual Studio Installer as Administrator, select to modify your current installation and add "Game development for Unity"
If you add a new c# script in Unity now, and open it (automatically) with Visual Studio, it is not described as "Miscellaneous" at the top of the window but with "Assembly-CSharp", and the autocomplete works.
i found my solution by creating the .cs file from visual studio itself instead of unity editor
right click on project folder in solution explorer
add > new item
type "unity" on the search field on the top right
select "CSharp MonoBehaviour"
name your script on the bottom and click Add
In my case, correct .net version was not installed on my PC. I install the .net 3.5 on my pc and that worked for me.
For Windows or macOS:
Download/Install the Visual Studio IDE (with Unity Tools)
When installing, make sure you include installation of
Game development with Unity
Then using Unity (you can double click one of your C# files), open a new C# project and the Visual Studio IDE should open with your new project structure.
From there, you should be able to see what you are looking for.
For example:
For Linux (suggestion):
Try Monodevelop - Additional Information, it provides code completion/hints.
My autocomplete also didn't work because Visual Studio Tools for Unity wasn't installed. So, after you install that, delete the auto generated Visual Studio files. Others said that you open file again and the problem is solved but it's not.
The trick is: instead of normally double-clicking the file, you need to open the C# file from Unity by right click and then "Open C# Project".
The issue I faced was that the C# Project was targeting a different .NET Framework (4.7.2), whereas the Unity project had a different target (.NET 3.5).
I fixed this by changing the target in Unity as-
File -> Build Settings -> Player Settings -> Other Settings -> API
Compatibility Level : Set it to the .NET version you already have
installed (Check your .NET Version here). In my case, it was 4.x
After this, Visual Studio worked perfectly and autocorrect was fixed too.
Try pressing Ctrl + Alt + Space (which toggles between suggestion and standard completion modes)
For some odd reason, the "Game development with Unity" tool can become disabled in Visual Studio.
To fix this..
Open Visual Studio
Go to Extensions → "Manage Extensions" → Installed
Find "Visual Studio 2019 Tools for Unity"
If it is disabled, enable it
Restart VS

The following works for me.
Go to Edit->Preferences->External Tools->External Script Editor Select Scripting Editor
I solved to install the same version of .NET on WIN that was configured in my Unity project. (Player Settings)
Go to Options on the Tools menu and then select Documents in the Environment node. (If Documents does not appear in the list, select Show all settings in the Options dialog box.)
Put a tick on "Miscellaneous files in Solution Explorer" and Click OK. (This option displays the "Miscellaneous Files" node in Solution Explorer. Miscellaneous files are files that are not associated with a project or solution but can appear in Solution Explorer for your convenience if you tick this option.)
Locate your file in the Solution Explorer under "Miscellaneous Files". Then drag and drop your file to where it should belong and voila! This will copy the file to where you drop it. You may now safely delete the older file under Miscellaneous Files folder if you wish to do so

In case Scripts folder is not visible:
Click on "Show all files" in Solution Explorer
Locate the Scripts folder.
Right Click on Scripts and select "Include in Project"
Keep in mind that if you are using the ReSharper tool, it will override the IntelliSense and show it's own. To change that, on VS, go to Extensions -> ReSharper -> Options -> IntelliSense -> General then choose Visual Studio and not ReSharper.
Before restarting and/or re-installing VS, First try opening any other of your projects to see if Intellisence works, if it does, then issue probably lies with your current project. First, most probable victim would be the NUGET packages with pending updates. To Fix this,
Right click on references
Proceed to Manage NUGET Packages Under NUGET Packages
proceed to updates Install Updates and recheck Intellisence
I tried all of these but ended up finding out that I needed to right-click the solution in Solution Explorer and add existing items and find the C# assembly file in Window's Explorer. There seem to be a bazillion different problems that give you this error, this is likely the most simple solution. If you double click on your script from unity, it does not seem to drag the assembly along.
Another possible fix:
In the project window, click on the Assets folder
Right click, and Create -> C# Script
Double click that, and wait.
For some reason, this work.
None of the above solutions worked for me. However I opened the ProjectName.CSPROJ file and manually added the new file and it worked like charm
What worked me is that I copied all the code inside the broken class and removed that file.
Then, I opened an empty file with the same name and pasted back.
Result: beautiful syntax highlights came back!
"Preferences" -> "External tools" -> set you exteranl tool
Thats one fix. Also for VS you can use ReSharper by JetBrains, but I recommend use Rider. That one is also free for students.
It provides less performance than visual studio, but more than VS+Resharper definitely.
Have a good day, mate)
Try with combination: Ctrl + Alt + Space
one of the above methods are worked for me and I just found a solution to this problem,
1. First, go to the project directory and delete .sln file
2. Second, go to unity and double click your script. Then Visual Studio will be open with an error,
Then click ok and close Visual Studio editor.
Finally, turn off your Windows Defender and then go to your project directory and there will be .csproj file. Just double click and open this from your Visual Studio editor and open the scripts folder inside the assets folder and open the scripts and autocompletion will be working perfectly fine.
These actions solved the problem for my projects in Visual Studio 2022

How do I open multiple projects/folders in a single Visual Studio Code instance, and open multiple files in single view? Does it has any option for future change request?
Not sure why the simplest solution is not mentioned. You can simply do File>New Window and open the other project in the new window.
Update
This is now available out of the box as of October 2017. From the blog post:
This was our #1 feature request - it's been a while coming but it's here now.
The complete documentation is here.
You can work with multiple project folders in Visual Studio Code with multi-root workspaces. This can be very helpful when you are working on several related projects at one time. For example, you might have a repository with a product's documentation which you like to keep current when you update the product source code.
Original answer
Currently the Insider channel of VSCode gives us this out of the box.
Read more from the blog post.
Update
As mentioned in several other answers here, this 'accepted' answer is outdated and is no longer correct. VS Code now has the concept of a 'workspace' which lets you add several 'root' folders to VS Code in the same window.
For instance, when working on a project in one folder that utilizes shared code held in a different folder, you can now open both the project folder and the shared folder in the same window.
To do this you use the Add folder to Workspace... command. VS Code then saves this configuration in a new file with a .code-workspace extension. If you double-click that file, VS Code will re-open with both folders present.
Original Accepted Answer (Outdated)
As described in The Basics of Visual Studio Code article:
"VSCode is file and folder based - you can get started immediately by opening a file or folder in VSCode."
This means the concept of solution and project files, like the .sln and .csproj, have no real function in VSCode other than that it uses these only to target and identify which language to support for Intellisense and such.
Simply put, the folder you open is the root you work with. But of course there is nothing from stopping you to open multiple windows.
As for the request features options, navigate to Help > Request Features which will redirect you to the UserVoice page of VSCode.
Support for multi-root workspaces is now enabled by default in the latest stable release [November 2017 release].
The File > Add Folder to Workspace command brings up an Open Folder dialog to select the new folder.
If you are using unix like OS, you can create a soft link to your target folder.
E.g. I want to see golang source while I am using VSCode. So, I create a soft link to go/src under my project folder.
ln -s /usr/local/go/src gosrc
Hope this helps!
Update: 11/28, 2017
Multi Root Workspaces[0] landed in the stable build, finally.
https://code.visualstudio.com/updates/v1_18#_support-for-multi-root-workspaces
[0] https://github.com/Microsoft/vscode/issues/396
You can open any folder, so if your projects are in the same tree, just open the folder beneath them.
Otherwise you can open 2 instances of Code as another option
On Windows it's possible to use mklink to create directory symbolic links to the needed folders. Then keep them together in a folder, and VSCode will list the content of these.
c:\>mklink /D c:\dev\MyWork\scripts c:\ProjA\scripts
symbolic link created for c:\dev\MyWork\scripts <<===>> c:\ProjA\scripts
c:\>mklink /D c:\dev\MyWork\styles c:\ProjB\styles
symbolic link created for c:\dev\MyWork\styles <<===>> c:\dev\ProjB\styles
This is very similar to #NeilShen's idea, I guess.
Multiple Folders in VS
Click ->File ->Add Folder to Workplace.
Step 1.
Choose which project to work ->Add(press)
Step 2.
October 2017 (version 1.18):
Support for multi-root workspaces is now enabled by default in the Stable release: https://code.visualstudio.com/updates/v1_18#_support-for-multi-root-workspaces
Now we can open multiple folders in one instance, Visual studio code has named as Workspace ("Area de Trabajo"). Take a look at the images, it´s very simple.
Or you can just select multiple folders and then click open.
Go to File> Open Folder, then select multiple folders you want to open and click Select Folder
Just put your projects in the same folder and simply open that folder in vscode.
Now your projects will appear like:
GROUP OF PROJECTS
PROJECT 1
Contents
Contents
PROJECT 2
Contents
Contents
It's not possible to open a new instance of Visual Studio Code normally, neither it works if you open the new one as Administrator.
Solution: simply right click on VS Code .exe file, and click "New Window"
you can open as many new windows as you want. :)
You can install the Open Folder Context Menus for VS Code extension from Chris Dias
https://marketplace.visualstudio.com/items?itemName=chrisdias.vscode-opennewinstance
Restart Visual Studio Code
Right click a folder and select "Open New Workbench Here"
Open New Workbench Here
You can open up to 3 files in the same view by pressing [CTRL] + [^]
What I suggest for now is to create symlinks in a folder, since VSCode isn't supporting that feature.
First, make a folder called whatever you'd like it to be.
$ mkdir random_project_folder
$ cd random_project_folder
$ ln -s /path/to/folder1/you/want/to/open folder1
$ ln -s /path/to/folder2/you/want/to/open folder2
$ ln -s /path/to/folder3/you/want/to/open folder3
$ code .
And you'll see your folders in the same VSCode window.
you can create a workspace and put folders in that :
File > save workspace as
and drag and drop your folders in saved workspace
You can use this extension known as Project Manager
In this the projects are saved in a file projects.json, just save the project and by pressing Shift + Alt + P you can see the list of all your saved projects, from there you can easily switch your projects.
To run one project at a time in same solution
Open Solution explorer window -> Open Solution for Project -> Right click on it -> Select Properties from drop down list (Alt+Enter)-> Common Properties -> select Startup Project you will see "current selection,single selection and multiple selection from that select "Current Selection" this will help you to run one project at a time in same solution workspace having different coding.
You can simply add folders (as many you want) in your workspace as shown in this image:
Image
And use them unhesitatingly.
