Settings Persistence

Only for packaged applications.

AppContext.cs:

using Microsoft.Windows.Storage;
using WinUI3Utilities.Attributes;

namespace Sample;

[AppContext<AppConfig>]
public static partial class AppContext
{
    public static string AppLocalFolder { get; private set; } = null!;

    public static void Initialize()
    {
        AppLocalFolder = ApplicationData.GetDefault().LocalFolder.Path;
        InitializeConfiguration();
        AppConfig = LoadConfiguration() is not { } appConfigurations
            ? new() : appConfigurations;
    }

    public static void SetDefaultAppConfig() => AppConfig = new();

    public static AppConfig AppConfig { get; private set; } = null!;
}

AppConfig.cs:

using WinUI3Utilities.Attributes;

namespace Sample;

[GenerateConstructor]
public partial record AppConfig
{
    public int WindowWidth { get; set; } = 1280;
    public int WindowHeight { get; set; } = 720;
    ...
}

When saving configuration, you can use the following code:

AppContext.SaveConfiguration(AppContext.AppConfig)
