Microsoft.Practices.Unity.dll中发生了类型为'Microsoft.Practices.Unity.ResolutionFailedException'的未处理异常

Question

我想知道是否有人可以帮助我？ 我从一个不在这里的开发人员那里选择了一个项目，我需要重建他的一个应用程序。

该应用程序将成功构建，但是如果我尝试运行它，则会出现以下错误：

  

类型的未处理异常   “ Microsoft.Practices.Unity.ResolutionFailedException”发生在   Microsoft.Practices.Unity.dll

     

其他信息：依存关系的解析失败，键入=   “ App.MainForm”，名称=“（无）”。

程序在这一行中断：

_mainForm = container.Resolve<MainForm>();

我拥有的全部代码如下：

    namespace Refunds
{
    internal class RefundApplicationContext : ApplicationContext
    {
        private TerritoryForm _territoryForm;
        private MainForm _mainForm;
        private IRefundProcessorConfig _config;

        public RefundApplicationContext()
        {
            using (IUnityContainer container = new UnityContainer())
            using (ContainerControlledLifetimeManager manager = new ContainerControlledLifetimeManager())
            {
                container
                    .AddNewExtension<BuildTracking>()

                    .RegisterType<IDirectDebitBusinessServiceFacade, DirectDebitBusinessServiceFacade>();

                _territoryForm = container.Resolve<TerritoryForm>();
                _mainForm = container.Resolve<MainForm>();
                _config = container.Resolve<IRefundProcessorConfig>();
            }


            _territoryForm.FormClosed += new FormClosedEventHandler(_territoryForm_FormClosed);
            _mainForm.FormClosed += new FormClosedEventHandler(_mainForm_FormClosed);

            _territoryForm.Show();

            _mainForm.Show();
        }

        private void _territoryForm_FormClosed(object sender, FormClosedEventArgs e)
        {
            if (_territoryForm.DialogResult == DialogResult.OK)
            {
                _config.Territory = _territoryForm.Territory;

                _mainForm.Show();
            }
            else
                ExitThread();
        }

        private void _mainForm_FormClosed(object sender, FormClosedEventArgs e)
        {
            ExitThread();
        }
    }
}
