I found that when using the old project template, the language class library cannot be loaded。

The test projects has two project .they are NET 472, the [TestHandyControls] not working properly the [TestHandyControlsSDKTemplate] working ok

Steps to reproduce the bug

Create project with "WPF Application (.Net framework)" not "WPF Application".

I test .Net framework 4.7.2.

    /// <summary>
    /// App.xaml 的交互逻辑
    /// </summary>
    public partial class App : Application
    {

        protected override void OnStartup(StartupEventArgs e)
        {
            base.OnStartup(e);

            ConfigHelper.Instance.SetLang("zh-CN");
        }
    }

 // in MainWindow
        private void Button_Click(object sender, RoutedEventArgs e)
        {
            HandyControl.Controls.MessageBox.Show("adsfasdf");
        }
