Steps to reproduce

With today’s release of .NET 8, I updated Visual Studio 2022 to install .NET 8 and removed the .NET 7 runtime. After the suggested reboot, PowerShell 7 was broken, and reinstalling it didn’t help:

Uninstalling the dotnet tool distributed version and using the WinGet distributed version was an effective workaround.

Expected behavior

PowerShell works.

Actual behavior

PowerShell crashes on launch.

I must admit I am not a fan of dotnet tools, especially global ones on Linux, because they are not global, they are private to the root user.

That’s because you’re using the root user. It’s private to the account you’re using (and I’d strongly disrecommend using the root user as your interactive account).

“Global” means “not tied to a specific project”, not “global to the machine”. That’s also true on Windows, as installing a global tool places it into your user folder. Here is an example that illustrates that (and also shows how a tool that needs a specific runtime should properly surface that requirement, rather than just outright crashing):

 pwsh$ dotnet outdated
You must install or update .NET to run this application.

App: C:\Users\bradwilson\.dotnet\tools\dotnet-outdated.exe
Architecture: x64
Framework: 'Microsoft.NETCore.App', version '7.0.0' (x64)
.NET location: C:\Program Files\dotnet\

The following frameworks were found:
  2.0.9 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
  3.1.32 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
  5.0.17 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
  6.0.25 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
  8.0.0 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]

Note where the executable is located.

Looking back at the original error message it suggests that it finds and uses the 8.0 runtime but fails to find a suitable Microsoft.Management.Infrastructure assembly.

Thank you @bradwilson for reporting this! There is another workaround for it. In the pwsh.runtime.config file under $pshome, change the value of rollForwardOnNoCandidateFx from 2 to 1.

The problem isn’t that it requires .NET 7, it’s that installation via dotnet tool when .NET 7 isn’t installed isn’t blocked and/or indicates the .NET 7 requirement.
