Sorry, I'm a newbie here. I've spent a few hours now trying to get intellisense to work on VS code and have followed multiple Youtube guides. No luck. I've installed and uninstalled everything multiple times. I keep getting this message.
F:\Program Files\dotnet\sdk\6.0.401\Microsoft.Common.CurrentVersion.targets(1220,5): Error: The reference assemblies for .NETFramework,Version=v4.7.1 were not found. To resolve this, install the Developer Pack (SDK/Targeting Pack) for this framework version or retarget your application. You can download .NET Framework Developer Packs at https://aka.ms/msbuild/developerpacks
It tells me to install the developer pack, but it already is installed? Any idea of how to fix this? Please help.
Primarily, this has to do with the VS code extensions and Installation of the Unity editor on Unity HUB.
In VS code, install the extension: C# for Visual Studio Code (powered by OmniSharp).
While installing the unity editor through Unity HUB, make sure you are installing Microsoft visual studio community.

My Flutter Doctor is saying:
Visual Studio - develop for Windows
X Visual Studio not installed; this is necessary for Windows development.
Download at https://visualstudio.microsoft.com/downloads/.
Please install the "Desktop development with C++" workload, including all
of its default components.
How can I fix this problem?
It's basically saying that if you want to develop your Flutter application for Windows you will need to install Visual Studio 2022 and while installing Visual Studio 2022 you will need to download this: Desktop development with C++
Also, you have to install the third link in this: Visual-studio
You could also get desktop development with the C++ tool after installing Visual Studio and then navigating to tool → Get tools and features → Desktop development with C++.
The error means install Visual Studio, and this is different from Visual Studio Code. It's an IDE from Microsoft.
For those who may be using a weak computer and can't afford to install the full Visual Studio, you only need to install a few components from Visual Studio to get Flutter to run on your computer without errors. These components are:
MSVC v142 - Visual Studio 2022 C++ x64/86 build tools.
Windows 10 SDK (for Windows 10 users)
C++ CMake tools for Windows.
In total, they should occupy around 8 GB or so.
As it states, you need to download Visual Studio (which is different from Visual Studio Code).
When installing it, remember to select the required package Desktop development with C++:
This will not prevent you from developing Mobile apps, but it's a requirement only for Windows Development.
Is unnecessary to install the "Desktop development with C++" if you don't want to develop desktop applications for Windows using Flutter.
If you only want to develop mobile apps using Flutter, you can run
flutter config --no-enable-windows-desktop
to disable the desktop support for your Flutter projects. After that, when you run the flutter doctor command again, you will no longer see the warning.

Only two steps are required.
Install Visual Studio 2022 (Link: https://visualstudio.microsoft.com/downloads/)
Install Visual Studio Code (Link: https://code.visualstudio.com/)
Your code will run smoothly.
My solution was a bit simpler. Uninstall everything all build system's from VS. Then reinstall Visual Studio Community 2022, restart then try again. Might get a warning about nuget but it should fix the issue.
With the newest android installer "android-studio-2022.1.1.19-windows" there would be a jbr and jre folder existing, hence creating a link from jre to jbr would not work.
What you can do is copy the contents of the items in jbr into the jre folder and this would resolve the error.
Make sure to install Visual Studio Code.
Open the Visual Studio download page:
I have a clean install of Ubuntu 20.04 LTS. I want to install Visual Studio Code, .NET SDK 5.0, and what seems to be the best suggested C# extension, this, the OmniSharp one.
I first tried to install with the Ubuntu Software app. In Visual Studio Code I installed the suggested OmniSharp extension. When trying to build a project, I got the mentioned error.
I tried installing using the terminal with this tutorial which seems good and straighforward - same error, when at the console app example stage after running dotnet new console.
This SO question has three proper suggestions, though I would like to use the latest SDK, and I do not have Mono installed, also I want to use Visual Studio Code, as far as I know, that is a newer approach than Mono.
The omnisharp.path": "latest solution does not work.
i faced the same problem and in the end i find the solution here

I'm trying to get a project to work that i downloaded this link over here, from github.
I've followed all the (configuration) steps in the install guide and i am using the exact versions of the software as described in the guide.
The problem seems to be that some references to the Windows namespace do not work.
I've tried adding it but i can't get it done in the usual way.
The error messages i get when building in unity:
When i open the project in visual studio 2015 update 3 (after building it in unity):
It seems that the option to simply add the reference in visual studio is not present in this kind of project.
I think this shouldn't be to hard to resolve but i lack the skills and experience as i usually develop windows apps solely in visual studio.
EDIT
These are the configurations I used:
i open the project in visual studio 2015 update 3
You should use Visual Studio 2017 with the latest Win10 SDKs.
Using Unity 2018.3.X just installed does not let you use Visual Studio Code nor MonoDevelop to code right.
Precompile is disabled
No debugger
No autocompletion
Errors everywhere
I solved it myself with some hours dedicated to this thing.
I was installing Visual Code as usual on a new computer but when trying to edit code the autocompletion did not work, also tons of errors popped.
When I installed I added the normal plugins for Unity in Visual Code
C#
Unity debugger
When reloading Visual Code, the Omnisharp log said that the compiler did not find the .NET Framework 4.5 and anything works within your C# scripts.
When looking into it I found this folder in Windows.
(If someone knows where it is in iOS share it please)
C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework
That folder showed folders with the versions of the frameworks installed.
In my case, those were 3.0 and 4.5.2.
The problem is that for some reason it does not detects the version 4.5.2 as 4.5 so to fix it normally you should install version 4.5, the problem is that you cant get it anymore.
To solve this, look at the Omnisharp log and change the folder name to the one your Omnisharp says, in my case I changed the name of 4.5.2 to 4.5 and my problem was solved.
I have seen more cases where the version the Omnisharp wants is different, just download the 4.X version you want from this link and change the folder name if you need.

Keep you .NET Core updated too to avoid more problems.
I'm trying to build Unity application for Hololens device on Visual Studio 2017 and I'm getting the following errors:
Metadata file '...\GeneratedProjects\UWP\Assembly-CSharp-firstpass\bin\x86\Release\Assembly-CSharp-firstpass.dll' could not be found
Metadata file '...\GeneratedProjects\UWP\Assembly-CSharp\bin\x86\Release\Assembly-CSharp.dll'
I'm aware of the similar question here but uninstalling and installing the latest versions of both Unity and VS did not help. Neither did starting a completely new project. I'm using now the latest versions of Unity (2017.1.0f3) and Visual Studio 2017 (15.3.0).
I've tried uninstalling both applications. Everything was working fine yesterday but then I downloaded additional components to Visual Studio (ASP.NET) and the Hololens build stopped working. Any idea how I could fix the issue?
I can see the Assembly-CSharp-firstpass.dll in Unprocessed folder under the path it's searching for it and even tried to copy it to the correct path but it did not help. I have also tried to build the project without ticking the Unity C# Projects but I get a different error then.
Update
I found this post on Unity forums and I think it's the same issue I have: https://forum.unity3d.com/threads/net-scripting-backend-and-visual-studio-2017-3-incompatibility.487833/
A workaround for this issue is to manually modifiying The "UAP,Version=v10.0.xxx" to "UAP,Version=v10.0" In the project.lock.json files of the GeneratedProjects.
Other solutions to this problem include a downgrade to Visual Studio 2015, or using the patch that the link you provided has.
