Removing JsonSettingsProvider and Using ApplicationData for Unpackaged Apps

[ghost1372]

Today, WinAppSDK 2.2 was released, and we can now use ApplicationData.GetForUnPackaged for unpackaged applications. As a result, there is no longer a need for different providers, and we can rely on a single provider across both packaged and unpackaged apps.

As soon as the Gallery is updated to version 2.2, we can start migrating away from providers and use ApplicationData for unpackaged applications as well.

It's packaged mode currently. So feel free to remove JsonSettingsProvider!

WinUI-Gallery/WinUIGallery/Helpers/SettingsHelper/Providers/SettingsProviderFactory.cs

Lines 11 to 24 in 00b0f81

	if (NativeMethods.IsAppPackaged)
	{
	return new ApplicationDataSettingsProvider(ApplicationData.GetDefault().LocalSettings);
	}
	else
	{
	var folder = Path.Combine(
	Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData),
	ProcessInfoHelper.ProductName
	);
	Directory.CreateDirectory(folder);
	var filePath = Path.Combine(folder, "AppConfig.json");
	return new JsonSettingsProvider(filePath);

But we'd better keep them for developers to check

@hoshiizumiya
I realized that the new API doesn’t seem to be working properly as expected. I reported it here
microsoft/WindowsAppSDK#6557
did I misunderstand something, or is there actually an issue?
