c# - wpf 应用程序在 Debug模式下运行，但在没有调试的情况下不会运行

Question

我的 WPF 应用程序在 VS2015 中以 Debug模式成功运行。但是，当在没有调试的情况下启动时，应用程序会启动并立即完成。从 Debug/Release 文件夹启动 exe 文件时也会发生同样的情况。事件查看器显示以下 .Net 运行时错误:

我知道同一个问题有很多问题，但还没有解决方案解决我的问题。

在运行期间 MainWindow 甚至不会出现。因此，我将所有 OnStartup 方法移动到 try catch block ，试图用 MessageBox 识别此异常，但 MessageBox 也没有出现。

    public partial class App : Application
{
    void App_DispatcherUnhandledException(object sender, DispatcherUnhandledExceptionEventArgs e)
    {
        e.Handled = true;
    }


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

            Ioc.Setup();

            Current.MainWindow = new MainWindow();

            Current.MainWindow.Show();
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }
    }
}

我已经上传了完整的 solution到谷歌驱动器。也许它会更有用。

终于找到原因了。该问题与使用私有(private) setter 绑定(bind)到公共(public)变量的双向绑定(bind)有关。使此 setter 公共(public)应用程序成功运行后。
