I’ve installed Microsoft Visual Studio Community 2019 Version 16.9.4 and tried to create a simple console application to print “Hello World”.
If I run the app with dotnet run from the Windows Command Prompt, it will run successfully, but opening the project in VS and trying to start the console app is causing the following error:
Unhandled Exception: System.BadImageFormatException: Could not load file or assembly ‘System.Reflection.Metadata, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’ or one of its dependencies. The file or directory is corrupted and unreadable. (Exception from HRESULT: 0x80070570)
I’ve already tried to start the console app as x86 and x64, but that did not help.
Another attempt was to uninstall VS 2019 and install VS 2017 Community. Have the same exception when I build the console app.
Unhandled Exception: System.BadImageFormatException: Could not load file or assembly 'System.Reflection.Metadata, Version=1.4.3.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The file or directory is corrupted and unreadable. (Exception from HRESULT: 0x80070570)
Could someone please help me with this?

I've been trying to run x86 assembly code on my machine for schoolwork. Sadly I've been getting this error when trying to build the project files and I can't figure out what it's about and how to fix it:
Error MSB4175 The task factory "XamlTaskFactory" could not be loaded from the assembly "Microsoft.Build.Tasks.v4.0, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a". The system cannot find the path specified hi C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Microsoft\VC\v170\BuildCustomizations\masm.targets 70
Has anyone had the same problem? I've tried making new projects, running as administrator, done a clean install of Visual Studio and all the packages, even factory reset my laptop.
I have a problem with installing Visual Studio 2022 from https://visualstudio.microsoft.com/fr/downloads/

Last night I upgraded my Visual Studio 2017 to the latest version 15.7.0. Since then all my projects are not running any more.
The error I am getting:
Could not load file or assembly 'System.Web.RegularExpressions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
I tried adding manually a referece to the DLL, I am still getting the error
I fixed the issue by 1) updating Visual Studio from 15.7.0 to 15.7.1 2) repairing the installation
I've installed the latest FSharp bundle, but now whenever I hit control-spacebar in Visual Studio, I get this error:

Also, when I try to compile, I get the following errors:

On top of that, I get the following errors when I try to run fsi.exe:

Note: I can still run fsi.exe for F# 3.0. I'm only having this issue with 3.1 (C:\Program Files (x86)\Microsoft SDKs\F#\3.1\Framework\v4.0)
Any idea how I can get back to functioning F#?
Edit 3
It appears that I am again able to compile my F# projects after numerous repair installs/system reboots of things. The issues with fsi.exe and Visual Studio Intellisense remain.
Everytime i try to open Visual Studios 2012, an error message displays
" Could not load file or assembly 'PresentationFramework, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e25' or one of its dependencies. The system cannot find the file specified."
Any idea what is wrong? How to fix this?
Try to Uninstall the Visual Studio that you have and download it from http://www.microsoft.com/visualstudio/esn/2013-preview. It works for me perfectly.
