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.

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

I have a huge solution with multiple projects. Sometime I need to navigate to a file in Solution Explorer. Using the VS 2010 'Navigate To' feature I can open any file by name in Visual Studio 2010 but I want to be able to select the file in Solution Explorer as well?
There's an option to track the active (open and viewed) item in the solution explorer. If the file is in view, the file in the solution explorer will be selected.
Tools->Options->Projects and Solutions->Track Active Item in Solution Explorer
VS2012 added a new command called SolutionExplorer.SyncWithActiveDocument. The default shortcut for c# is Ctrl+[,S
This command will navigate to the active file in the Solution Explorer.
Also, it seems that you need to have the "Track Active Item in Solution Explorer" option turned off.
With ReSharper installed Shift+Alt+L will find the current file in Solution Explorer in Visual Studio 2008+.
I found the track option to be a little annoying.
I prefer to use DPack. It contain "Locate In Solution Explorer" operation, plus many other features (some are less powerful in VS2010, like their browsers), and it's free.
Note that ReSharper also have the locate feature that works batter than DPack's (in some cases, DPack's locate won't work if the file is collapsed behind folders), but you don't want to buy ReSharper only for this feature.
Brian Schmitt has a great Locate File in Solution Explorer – Visual Studio Macro post for this. The macro is extremely simple and quick. Basically it toggles the setting
Tools->Options->Projects and Solutions->Track Active Item in Solution Explorer
so that the current file ends up selected in the Solution Explorer but, because it is not left on, you don't get irritated by Solution Explorer nodes being expanded for all the files you access.
Public Sub LocateFileInSolutionExplorer()
DTE.ExecuteCommand("View.TrackActivityinSolutionExplorer")
DTE.ExecuteCommand("View.TrackActivityinSolutionExplorer")
DTE.ExecuteCommand("View.SolutionExplorer")
End Sub
Bind a Keyboard ShortCut to this custom macro to effectively create what should be a built-in Visual Studio feature.
If you have ReSharper and want to add "Locate in Solution Explorer" to the tab's context menu:
Go to Tools -> Customize -> Commands -> Context Menu
Select "Other Context Menus | Easy MDI Document Window".
Click "Add Command".
Choose "Resharper" -> "ReSharper_LocateInSolutionOrAssemblyExplorer" (in VS2019, the category name was changed to "Extensions")
"OK" -> "Close"
Now, when right click on any tab and you'll see a new option: Locate in Solution Explorer.
UPDATE:
Following the comment from #jeremy-paskali, you can set a keyboard shortcut for this command:
Go to Tools -> Customize -> "Keyboard..."
Search for "ReSharper.ReSharper_LocateInSolutionOrAssemblyExplorer" in the "Show commands containing" field and select it.
Review the currently assigned shortcuts in the drop down below.
Make any changes, if needed.
"OK" -> "Close"
Visual Studio 2012 has a new shortcut Ctrl [, S. Yes you have to type Ctrl [ and then release and then immediately type S (or click the little sync icon at the top of Solution Explored). It will synchronize to the item.
Of course you can change the shortcut. I think I'll try Alt+L for locate.
If you want to change the shortcut, it's command name under Options\Environment\Keyboard is SolutionExplorer.SyncWithActiveDocument.
Usually this is more useful than always tracking, which in older versions always was a disaster because it would track 100 items in a row and then be jumping all over the place...
I know its little too late, but hope it helps someone else. The best option now is to install Microsoft Visual Studio add on called - Productivity Power Tools.
http://visualstudiogallery.msdn.microsoft.com/d0d33361-18e2-46c0-8ff2-4adea1e34fef
With this comes "Solution Navigator" (alternative to Solution Explorer, with a lot of benefits) - which then you can use to filter the files to only show "Open". You can even filter files to show "Edited" and "Unsaved".
In the event you want to only track the current file through a
keyboard shortcut - the activity is
"View.TrackActivityinSolutionExplorer" (assign keys here -> Tools -
Options - Environment - Keyboard)

This worked for me
There are several build-in ways you can accomplish this nowadays:
Configure VS to track the active item in Solution Explorer: This can be accomplished by selecting "Track active item in Solution
Explorer" at
Tools > Settings > Projects and Solutions > General
Use "Sync with active document": This can be accomplished in 2 ways.
Firing the SolutionExplorer.SyncWithActiveDocument command by using the default key combination CTRL+]+S
CTRL+)+S if you happen to be using an AZERTY keyboard like me.
By using the "Sync with active document" button on top of the Solution Explorer. The button looks like 2 apposing arrows on top of each other.
If you're version is older then VS2019 Version 16.10.2 then this button looks like this:
From VS2019 Version 16.10.2 onwards this button will look like this:
And yet again Microsoft has changed the button icon in more recent versions of VS 2022:
In Visual Studio 2010 you can turn on the "Track Active Item in Solution Explorer" option. This will mean whenever you switch between documents the new document gets selected in Solution Explorer. This can be irritating if your solution has lots of folders, because as you move around files in your solution all the folders will be left open.
Visual Studio 2012 introduced the new "Sync with Active Document" feature. Three is a button for it at the top of Solution Explorer, or you can use the shortcut Ctrl + [, S.
This is actually built in to visual studio without the need for ReSharper (which I love BTW).
http://blogs.msdn.com/b/zainnab/archive/2010/03/29/track-active-item-in-solution-explorer-vstipproj0011.aspx
If you want to select the file in the solution explorer on command and don't want to install anything then I would recommend this macro.
I've tested it, setting the shortcut to Alt+T, and I can confirm that it works with VS 2010.
Thanks to Dan Vanderboom for writing it.
For Visual Studio 2017 using a French AZERTY keyboard the command is the same as stated by Aaron Carlson but the keyboard shortcut is different.
The AZERTY keyboard shortcut to navigate to the active file for c# is Ctrl+),Ctrl+S
I checked the shortcut hadn't changed for QWERTY users in VS2017 on this page
http://visualstudioshortcuts.com/2017/
Visual Studio doesn’t offer an easy way to locate the current file you’re editing in the Solution Explorer on demand. You can set the solution explorer to always stay in sync with this simple setting:
Tools > Options > Projects and Solutions > General. Check “Track active item in Solution Explorer”.
Thanks to Cory House
Start menu in Windows 7 has a feature: a programs, pinned to the top, can show a context menu with recently used files:
alt text http://img65.imageshack.us/img65/5149/contextmenustartmenuwin.png
Will Visual Studio 2010 be able to display also recently used Projects and Solutions?
It is possible to pin solution files to the recently used file list.
First make sure you already have Visual Studio pinned to the Start Menu.
Next, drag the Solution file on to the Start Menu so that it is pinned in the main list.
Now select the the Recently Used Files button for Visual Studio so that the list is showing.
Drag the solution file from the main list into the recently used file list.
You can now remove the solution file from the main list.
Beta 1 doesn't seem to support this yet. Its easily possible by using the new Taskbar APIs and specifically the custom categories feature. I think their main problem might be that the solution files are associated with an app called VSLauncher.exe (this small app determines what version of VS to load when you launch a SLN file).
If you want to "pin" your fav solution files to any version of VS, one option this is (I currently used this with VS 2008 and 2010 Beta 1:
Open Explorer and browse to any SLN file you want to pin.
Drag it and pin on the taskbar (it will pin to VSLauncher.exe; this is okay)
Now just repeat the steps for other SLN files.
When you click on a SLN file from the above pinned program's jumplist, another instance of VS2010/VS2008 will launch. It won't show your recent projects or solutions, but atleast it allows you to pin your fav/recent solutions manually. I think you can use this for CSProj or other project files as well.
