title: Where to save .Net MAUI user settings
body: <p>In Windows Forms and WPF applications we could <a href="https://docs.microsoft.com/en-us/dotnet/desktop/winforms/advanced/using-application-settings-and-user-settings?view=netframeworkdesktop-4.8" rel="noreferrer">use the Settings designer file to save user-specific settings</a>. The docs only mention .Net Framework (e.g. 1 - 4), not .Net Core or .Net (e.g. 5+). I've confirmed that the .settings format and designer still works in .Net 6 WPF on Windows with Visual Studio 2022 though.</p>
  <p>My questions is, is the <code>.settings</code> file format and designer still the recommended approach for <a href="https://docs.microsoft.com/en-us/dotnet/maui/what-is-maui" rel="noreferrer">.Net MAUI</a> applications? Will it work across all platforms (Windows, macOS, mobile)? If not, is the recommended approach to simply write your own custom file for saving your user settings, and if so, where should the file be written to? <code>Environment.SpecialFolder.ApplicationData</code> / <code>Environment.SpecialFolder.LocalApplicationData</code>, or somewhere else?</p>
