The installed ms-dotnettools.csharp (v1.25.0) extension does not seem to format the C# code : my C# files witch I try to format popups me about missing C# formatter

Visual Studio Code
There is no formatter for 'csharp' files installed.
[Cancel] [Install Formatter...]

I open in the VSCode the entire root folder, containing several projects (C#, Angular etc.), and when opening individual Cs files and try to Shift+Alf+F to format the file, it asks me for the formatter.

I have the following VSCode configuration

You need to either update .Net to 6+ or install a previous version of Omnisharp.

Version 1.25.0 requires .Net 6+. If that's not an option for your environment then you can install a previous version of the Omnisharp extension.

In order to do this, press ctrl/cmd + shift + x to bring the extensions side panel, then click on the configurations wheel and select 'Install another version'.

I tried 1.23.12 and the formatter is working now.

If you run into this issue again you can check the output of the extension to check what could be causing it.

I'm not sure if you found it already, but I'll leave it here in case someone else needs it.
