Why not create a service, WindowsIniService.

public string GetValue(string section = string.Empty, string name = string.Empty);

If section is empty, returns the first item.

I found Win32 API for this but it is for 16-bit compat https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-getprivateprofilestring. But worth taking a look.

https://en.wikipedia.org/wiki/INI_file

What we need in Files is very basic so something like this would work (all our work with INI files is read only).

var lines = File.ReadLines(iniPath);
var keys = lines.Select(line => line.Split('='))
	.Where(parts => parts.Length == 2)
	.ToDictionary(parts => parts[0].Trim(), parts => parts[1].Trim());

yeah but putting this in places where it needs makes you hard to maintain. Also, I like services because I plan to create Unit Tests for services in the future.

Can I work on?

I meant that we can use that for the service.
