Cannot find UnityEngine.InputSystem - visual-studio

I am currently working on a new unity project and to be honest i am new at this.
I need to use the InputSystem package but Visual studio does not recognize it.
This is the version of my VS. Microsoft Visual Studio Community 2019 Version 16.9.3 and the version of Unity is 2020.2.1
As you can see by the picture, my VS already knows that I am working in a Unity project.
So the first thing that I tried doing is to regenerate project files but it didnt work. I also selected my VS as my default external script editor.
This is my external tools.
I re-installed VS using unity hub but nothing happend.
Do you have any suggestions? I followed some tutorials I saw over the internet but I am still getting no positive results and to be honest, I am getting out of ideas.

Just tested out the package installation. I installed the package in a fresh, empty Unity project. Here are the steps that I went through which worked in my case:
Locate the Input System package in the Package Manager
Click install
A warning prompt will appear, click yes
Unity Editor should now get re-launched on it's own, wait for that to happen
If Visual Studio is open, close it
Open Visual studio - right click on the Assets folder and select Open C# project
UnityEngine.InputSystem namespace should now be available, if not, re-open Visual Studio one more time
Let me know if it works for you.

For me works when I install .NET and .NET Core and reboot the computer. (made this on Windows)

Target Framework not installed when opening a Unity project with Visual Studio 2022

I am trying to open a C# solution that has been generated from a Unity v2020.3.19f project with Visual Studio 2022. Opening it with Visual Studio 2019 works just fine, but there are reasons I'd like to be able to open it with v2022 (such as GitHub Copilot). I did not have issues with this on my previous install of Windows 10.
Upon opening the solution in VS2022, I get the following pop-up prompt for every project in the solution:
Choosing the first option updates the target project to .NET Framework 4.8 and loads the project, but the whole file appears with red lines. When hovering over an underlined bool Property, the error shows as: `CS0518: Predefined type 'System.Boolean' is not defined or imported.
Choosing the second option opens this URL in my browser, prompting me to install .NET Framework 4.7.1 targeting pack (which was already installed via the Visual Studio Installer). When I try to install the .NET Framework 4.7.1 runtime, the installer responds with .NET Framework 4.7.1 or a later update is already installed on this computer. When I try to install the .NET Framework 4.7.1 Developer Pack, the installer allows me to choose from "Repair", "Uninstall", or "Cancel". Repairing has no effect.
I installed both versions of Visual Studio (2019 & 2022) the usual way through the Visual Studio Installer, along with the "Game Development with Unity" workload, which tells me it's installed all dependencies just fine:
Here's what I've tried so far:
Uninstall & reinstall all versions of Visual Studio through the Visual Studio Installer
Uninstall & reinstall Unity, with the Visual Studio module installed through Unity Hub (which just opens the Visual Studio Installer for me to choose which version I want to install)
Regenerate project files through the Unity Editor
Uninstall any references to .NET Framework through the Control Panel
Try reinstalling .NET Framework targeting pack 4.7.1 either from the Visual Studio Installer or manually through the Microsoft SDK website from the prompt
Nothing works for me. Any help on how to make VS2022 stop complaining is greatly appreciated.
Update 1: I found a couple of threads where people suggested simply pressing the Regenerate project files button in "Edit -> Preferences -> External Tools`. This has not helped me.
Update 2: I've tried everything I can possibly imagine, in different orders and different combinations. I even reinstalled Windows 10 to no avail. It's like Visual Studio just doesn't want to accept that the .NET Framework 4.7.1 targeting pack is installed. Please help :(

If you modified the value of ProgramFilesDir(x86), just to modify it back to C:\ProgramFiles(x86) can solve the problem
That is a very interesting problem, my main solution for you to first try is to make sure you are even targeting the correct .net framework in UNITY before you even build the solution. You are using the .NET 4.x, you need to go into your configuration settings and player settings in unity and ensure its not on a different version, for me, unity still defaults to .net standard 2.0. Follow the steps located here. To do so.
Another solution is to see if that first option actually gives you errors that prevent you from using unity, because I know that Visual Studio Code has problems occasionally where it tells me im wrong, my program is wrong, every life choice I have made was poor and I am poor, yet in unity, there are no errors showing in the console and I can hit play no problem. In that case I just had to rebuild a few times and fiddle with vs code until omnisharp stopped yelling at me.
Apperently I have been in a similar situation as when you were getting the error "Predefined type 'System.Object' is not defined or imported" because looking into it, I already have clicked on some of the links, try this one if that error persists. If you cannot prevent the errors to begin with, I would recommend you trying to fix the upgraded version from option one as that is more than likely going to get you the closest to a solution.

IntelliSense doesn't show Unity hints

So I'm new to Unity and I'm watching a few tutorials to learn the basics. Something that got my attention is that in the videos they have an autocomplete and while I've got it too, it gives too few options. For instance it doesn't show the Debug or any of its properties. It runs fine but it's really annoying.
I don't know if it's related but it also lacks some coloration. Like in the videos Debug is colored orange but mine is not colored differently from the rest.
Not sure about your VS version and Unity version, but please update them if possible. For example, you have VS2017 15.8 and Unity 2018.1, then please update them to VS2017 15.9.17 and Unity2018.3.8 or higher.
And it seems to be one similar issue like this report in DC. You can find details from Sebastien Lebreton for trouble-shooting the issue there.
Make sure:
Visual Studio is set as your external script editor in Unity (Edit/Preferences/External Tools)
Visual Studio plugin is installed in Unity (Help/About must display a message like Microsoft Visual Studio Tools for Unity is enabled at the bottom).
Then check that the extension is properly installed in Visual Studio (Help/About).
You can try:
backup your project
quit both VS and Unity
remove all generated sln/csproj
remove the hidden .vs folder in VS Solution folder
remove the Library folder
re-open the project with Unity
In Unity, use Assets/Open C# Project to open that in Visual Studio
In addition to Lance Li-MSFT's answer I happened to observe this: When you create a new script (for example with "Add Component" -> "New Script") and then try to open it directly, this can happen. So after you created your script, give unity a few seconds to compile and then open it. For scripts that are opened to early, I did not manage to fix them. They just won't show IntelliSens hints, otherwise they work perfectly normal.
Just spent some time solving this
(VS 2022 community, Unity 2020.3.30f).
It happens that by defaut in Unity
Edit \ Preferences \ External tools
"External script editor" is set to "Open file by extension".
And script does open in VS 2022, and script compiles in Unity after editing, but it does not create .vs folder with all project related stuff.
So intellisence just did not kick in to Unity.
But after I set "External script editor" to Visual Studio, it started to work
(hints and coloration).

Visual Studio syntax highlighting / autocomplete not working correctly

My Visual Studio does not highlight or autocomplete any Unity3D commands any more. I created a new script when noticing that. I restarted VS, reinstalled VS, also reverted all script changes I made today in my project but the result is still the same. Also I now get errors when trying to open my project file. It says it needs a migration and isn't compatible with the current Visual Studio version installed.
The actual error reads "The application that is based on this project type was not found." [translated from German].
I found similar posts on the web where reinstalling VS resolved the issue. Unfortunately, it did not for me. This is how it looks:
Anybody knows how I can fix this?
Ok, I was able to resolve this issue using this trick:
"Do me a favor... if this is Visual Studio 2017... hit your start menu and find Visual Studio Installer... Run it... select "Modify" and select individual components... find Visual Studio Tools for Unity... if it's installed, untick it and uninstall it, then run the installer again and reinstall it. Otherwise, just tick it and install it."

xamarin project type incompatible

This error started showing from yesterday, I remember installing Web development packages and updates windows. Before that if was working fine.
If I reload project same error shows up.
The application which this project type is based on was not found.

I tried uninstalling Xamarin packages and reinstalling.
It did not solve the issue.
Now I am doing complete uninstall of MS Visual Studio 2017
Please note that no changes have been made to csproj or solution file.
I get the "xamarin project type incompatible" frequently. (VS2015)
The solution for me:
Close down VS.
In the src project folder delete the .vs folder.
Restart VS.
Complete uninstall of Visual Studio along with C++ distributables from Control Panel > Programs and Features and then re-installing Visual Studio fixed the issue. Seems its caused by errors in installation
Microsoft should code properly and let programmers know if there were errors and 'repair' option is supposed to fix them. I don't know why these things are missed out in roll-outs.

Console Application not found on visual studio 2015

I just download visual studio community to my pc. When i opened the vs-2015 and create new Console application project. i can't find it any where under the c# we installed templates or any templates.
Thinking about to uninstall and install again but this not the first time i uninstall and install this, i did installed and uninstall few time but still can't find the web Console Application template.
Thank you.
I had the same problem and found the solution on another site. Here are the steps that need to be performed:
Open a Visual Studio command window with admin privileges. This can be done from Windows search after clicking on the Windows button (or Start button - depending on the OS) located in the lower left corner. Make sure that you don't have any Visual Studio project open before proceeding.
Type in prompt in the search box and select "Developer Command Prompt". Right click on this and select run with admin privileges.
In the command window Enter:
cd C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE
In the command window then enter:
devenv /installvstemplates
This worked for me and I was able to create a new console project after this.
With my version of VS 2015 community edition, upon install there was a Console Application (Package) template available, which I mistakenly thought was a Console Application template. This is not the case. It is a web console application project and I only discovered this after trying to access the File and Directory classes in System.IO from my code. The compiler kept on complaining:
Error CS0234 The type or namespace name 'Directory' does not exist in the namespace 'System.IO' (are you missing an assembly reference?)
MyProject.DNX Core 5.0 ...
It still complained after putting in a reference to System.IO and even after changing the offending line of code to:
string DataPath = System.IO.Directory.GetCurrentDirectory();
A big clue here is the reference to DNX Core 5.0, which is an optimized run-time for ASP apps. It was at that point that I discovered that the Console Application (Package) template was also listed under the New Project window Templates / Visual C# / Web.
So, For others that may happen to find this post and think you are using a standard Console Application template, but have errors like "CS0234 The type or namespace "name" does not exist in the namespace..." then you could be using a Console Application (Package) template - which is probably not what you want and should be replaced by a regular Console Application. If you don't see it in the New Project window under Templates / Visual C#, then you should follow the steps above to install it.
EDIT
This is what my New Project window looks like after I performed the steps above:
Comparing this window with yours above, it appears to be somewhat different. Notice that "New Project" on my window is centered and for yours it is not. Also, at the bottom of the window yours has only Name, Location and Solution name, while my window adds a fourth item called Solution.
So, first thing, try clicking on Visual C# located in the left pane of your New Project window to see the templates available. Post that snapshot here. This can be done by selecting edit.
If you still don't see the Console Application template, then perhaps you downloaded a different version of Visual Studio 2015 than I did. So, here is the screen that pops up after selecting Help / About Microsoft Visual Studio on my system:
Compare this screen with yours and post a snapshot of your screen here. Also, what operating system are you using?
Thanks again Bob for your time to explained it to me, i am really appreciate that, I uninstalled and installed again from this link enter link description here, On my machine i have Visual Studio 2015(this one works) and Blend for Visual Studio 2015 is still missing template but i don't care it anymore if it work or not because i will use the one that works which is the Visual Studio 2015.
