Failed to install on a fresh installation of Fedora 37 with .NET 7

[CicadaCinema]

I installed the .NET SDK by running sudo dnf install dotnet-sdk-7.0 .

Version information:

[jazz@dracula ~]$ dotnet --list-sdks
7.0.102 [/usr/lib64/dotnet/sdk]
[jazz@dracula ~]$ dotnet --list-runtimes
Microsoft.AspNetCore.App 7.0.2 [/usr/lib64/dotnet/shared/Microsoft.AspNetCore.App]
Microsoft.NETCore.App 7.0.2 [/usr/lib64/dotnet/shared/Microsoft.NETCore.App]

I followed the installation instructions and modified my PATH as required:

[jazz@dracula ~]$ dotnet tool install -g git-credential-manager

Welcome to .NET 7.0!

I thought this might be related to #1011 but apparently not:

Removing dotnet-sdk-7.0 and installing dotnet-sdk-6.0 succeeds, as expected:

[jazz@dracula ~]$ sudo dnf install dotnet-sdk-6.0

... snip ...

[jazz@dracula ~]$ dotnet tool install -g git-credential-manager

I'm not sure whether .NET 7 is not supported or whether this is a bug - either way this requires looking into, I think.

Unfortunately .NET tools require the version of the .NET SDK corresponding to the framework version of the project(s) for which they're published. GCM (for macOS and Linux at least) is currently on .NET 6.0, which means users who want to install the tool will need to have the latest version of the .NET 6.0 SDK installed. I've updated the install instructions to reflect this - thank you for pointing it out @CicadaCinema!
