Как определить из кода библиотеки Standard платформу приложения (Forms, WPF, UWP, Framework, Core и т.д.)?

    public static bool IsWPF()
    {
        try
        {
            Activator.CreateInstance("PresentationFramework", "System.Windows.Window");
            return true;
        }
        catch
        {
            return false;
        }
    }

public class ViewModel: CommonWpf.ViewModelBase
{
    public class IRelayCommand SomeCommand {get;} = new CommonWpf.RelayCommand(....);
}

public class ViewModel: CommonUwp.ViewModelBase
{
    public class IRelayCommand SomeCommand {get;} = new CommonUwp.RelayCommand(....);
}

public enum ApplicationType { None, WinForms, UPF }
public static class LibConfiguration
{
    static ApplicationType _AppType = ApplicationType.None;
    internal static ApplicationType AppType
    {
        get
        {
            if (_AppType == ApplicationType.None)
                throw new Exception("Not inited. Call LibConfiguration.Init method first");
            return _AppType;
        }
    }
    public static void Init(ApplicationType appType)
    {
        if (_AppType != ApplicationType.None)
            throw new Exception("Already inited");
        _AppType = appType;
    }
}

ICommand CreateRelayCommand<T>(Action<T> execute, Predicate<T>? canExecute = null, bool raiseCanExecuteChangedOnRequerySuggested = true)
{
   var command = new RelayCommand<T>(execute, canExecute);
 
   if (raiseCanExecuteChangedOnRequerySuggested)
      CommandManager.RequerySuggested += (o, e) => command.RaiseCanExecuteChanged();
 
   return command;
}
