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.

I am using Microsoft Visual Studio Installer projects extension to create an installer for my app.
Works OK, but the problem is that the product name contains "š" character in it and the font used in the msi installer obviously doesn't support that character:
Anything I can do about that?
Some background info:
I initially developed the app in VS 2015 which had a free Install Shield Limited edition. Or maybe it was even VS2013, don't really remember... However, now I need to make some changes in the app. There was no problem with such a name in Install Shield back then. So I tried to open the project in VS 2022, but obviously Install shield's no longer an option. This is where VS Installer project comes in, but there's the problem with the diacritics...
This looks like an encoding issue. Try searching in the VS project properties for an option to set the encoding to Unicode. I don't use the VS projects that much, so I don't know if you have the option to change it not, but it might be there.
Also, if you are looking for a better free MSI packaging tool, try the Advanced Installer extension for Visual Studio. There is one for each version of VS.
Disclaimer. I work on the team building Advanced Installer.
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)

I have been trying to install Visual Studio for a couple of days now and none have operated. First I tried Visual Studio Community 2017 and the installer was installed and then the vs was installed but when I try and run it I got an error message that directed me to the ActivityLog file. I've tried uninstalling it then reinstalling it but that didn't work. I came across a solution that required me to try opening it using the Developer Command Prompt which I wanted to do but when I clicked on it from the Start menu it said that the link is missing. There was another Visual Studio program that had also installed and when I tried loading that one, it also directed me an ActivityLog file.
So I uninstalled the 2017 version and tried installing an earlier version hoping that it would work. I can reinstall for whomsoever would want to see the error message as well as the log file.
I then tried the 2013 version (since that is the one we use at school anyway). After downloading the file, I do not even get to an installation screen. A pop-up appears that says that the program requires the Microsoft .NET framework to work
Installation pop up window
The first time I tried it gave me options to accept and continue or cancel so I clicked on accept and continue and that was the end of it. Nothing happened after that. Now when I click on the installation file it just appears as in the picture above with no options. I tried to follow the instructions on Cannot install Visual Studio 2017 Community since that is the closet to my problem that I have found but it still didn't work.
Please help. I really need at least one Visual Basic to work.
I recently installed Visual Studio 2013 Ultimate version on my machine. I'm just trying to create a sample windows form project and trying to open the designer / form by double clicking on Form1.cs and I'm getting this weird error message:
"the service microsoft.visualstudio.shell.interop.iselectioncontainer already exists in the service container"
My system is already having Visual Studio 2010 which is working smoothly from a long time. I then installed Visual Studio 2012 which was giving the same problem as above. So I went ahead with installing VS 2013 hoping that I might be able to get rid of this issue, but no use.
Once I click OK on the error windows, I can see the following "message" in the bottom Error List window:
"The file 'C:\Users\ABCD\Documents\Visual Studio 2013\Projects\WebSite1\WindowsFormsApplication1\Form1.cs' does not support code parsing or generation because it is not contained within a project that supports code."
I have spent 2-3 days searching various blogs like these, all of which talk about previous version of Visual Studio like VS 2005 / VS 2008:
https://connect.microsoft.com/VisualStudio/feedback/details/311949/the-service-microsoft-visualstudio-shell-interop-iselectioncontainer-already-exists-in-the-service-container
Form inheritance in Visual Studio 2008 doesn't work
I have even tried uninstalling and reinstalling VS 2013, again no use.
It would be really great if someone can help me out in fixing this.
I've just had the exact same error message.
After compiling the solution(F6 or Build->Build Solution) it worked fine for me.
To deal with your issue, please first make sure that you installed latest updates on your Windows 8 machine, and then repair VS2013.
During your repairing process, please temporally turn off your anti-virus/antispyware software and repair VS2013 with the Administrator privilege.

The problem got resolved finally, after so many days and various frustrating tries to resolve the issue. I should thank Tim Atkins from Microsoft for helping me with resolving this issue.
Fix: When we tried 'gacutil /l system.design', we found that there were 3 variants of system.design; One from .Net 2.0 targetting MSIL, second from .Net 4.0 targetting x86 and last one also from .Net 4.0, but targetting MSIL.
On a working machine, there were only 2 entries, the .Net 4.0 one targetting x86 wasn't there. Hence we uninstalled this version using gacutil which did the magic. I was so relieved seeing the win forms popping up without any errors anymore :)
I changed the target framework from 4.5 to 4.6.1 and it fixed it for me. My assumption is sometimes when you change target framework back and forth and the process does not go through all the way (cancelling in the middle of changing it) - something happens that leads to this error. Hope that helps
I solved this be closing VS, deleting contents of the .vs folder where my solution is, restarting VS and recompiling.
Seems like one of those file/settings/caching problems that pop up now and then, might be after switching source branch.
VS2019, .net fw 4.6.2.
If your C drive (Where you are installing Visual Studio) does not have enough space, try moving some files from the C drive to another drives.
I’m using visual studio 2008 and moles version 0.93. Everything works well except when I try to debug any test that uses a Moled type. The test skips all my breakpoints. And I get the following message in the output window:
Unable to attach. Check for one of the following.
The application you are trying to debug uses a version of the Microsoft .NET Framework that is not supported by the debugger.
The debugger has made an incorrect assumption about the Microsoft .NET Framework version your application is going to use.
The Microsoft .NET Framework version specified by you for debugging is incorrect
Please see the Visual Studio .NET debugger documentation for correctly specifying the Microsoft .NET Framework version your application is going to use for debugging.
If I try debbuger.Break () I get a message: "No symbols are loaded for any call stack frame. The source code cannot be displayed."
I’m in a crunch right now chasing an issue with one our main components and it has been a pain (like I need novocaine) trying to figure anything out without being able to step through the code.
I want to take advantage of mole's "smooth debugging experience". However, I can't seem to get the debugger to attach at all.
Thanks,
Bzz

I had this problem when I moved a project from Visual Studio 2010 to Visual Studio 2008. Here's what I did to fix it.
Close Visual Studio. Navigate to the Debug/bin location. Delete the following files:
*.vshost.exe
*.vshost.exe.config
*.vshost.exe.manifest
Open the solution. Goto the project Settings. Under the Application Target Framework, select a framework lower than the one you are working with (you'll set it back later). Visual Studio will close and re-open your project automatically. Then set the Target Framework back to the original version you were working with. Rebuild all, and debugging will work properly.
