How to use XCT localization?

1. In App.xaml.cs

• Initialize LocalizationResourceManager with your resouce manager and optionally initial culture;
• Subscribe to PropertyChanged to ensure that culture for AppResources is updated when LocalizationResourceManager.Current.CurrentCulture is updated.

LocalizationResourceManager.Current.PropertyChanged += (_, _) => AppResources.Culture = LocalizationResourceManager.Current.CurrentCulture;
LocalizationResourceManager.Current.Init(AppResources.ResourceManager, initialCulture);

2. For static strings that use xct:Translate.

<ContentPage Title="{xct:Translate AppName}">

3. For dynamily generated strings use LocalizedString (currently in preview).

public LocalizedString AppVersion { get; } = new(() => string.Format(AppResources.Version, AppInfo.VersionString));

<Label Text="{Binding AppVersion.Localized}"/>

4. That's it. Now just do this when you need to change current culture:

LocalizationResourceManager.Current.CurrrentCulture = newCulture;

And after that every resource string in the program will be automatically updated.
