在我的引导程序中，我首先这样做：

    public static void Initialise()
    {
        var container = BuildUnityContainer();

        InitializeNServiceBus(container);

        DependencyResolver.SetResolver(new UnityDependencyResolver(container));
        ...
    }

而InitializeNServiceBus的内容是这样的：

    private static void InitializeNServiceBus(IUnityContainer container)
    {
        var typesToScan = new [] {
            typeof (RequestPasswordResetCommand),
            typeof (CreateAccountCommand)
        };

        Configure.With(typesToScan)
            .DefineEndpointName("somequeueonmysystem")
            .UnityBuilder(container)
            .XmlSerializer()
            //.MsmqSubscriptionStorage()
            .DisableRavenInstall()
            .DisableSecondLevelRetries() //we need timeout manager for this
            .DisableTimeoutManager() //we need raven db or similar for this //.RunTimeoutManager()
            .MsmqTransport()
                .IsTransactional(false)
                .PurgeOnStartup(false)
            .MsmqSubscriptionStorage()
                .IsTransactional(true)
            .UnicastBus()
                .ImpersonateSender(false)
            .SendOnly();
            //.CreateBus()
            //    .Start(() => Configure.Instance.ForInstallationOn<NServiceBus.Installation.Environments.Windows>().Install()); 
    }

但是，当我打开我的 MVC 应用程序时，我得到：

静态属性需要空实例，非静态属性需要非空实例。参数名称：表达式

这里指出了错误的来源：

Line 82: 
Line 83:             Configure.With(typesToScan)
Line 84:                 .DefineEndpointName("InCityS.Events.UI.Nuvonet")
Line 85:                 .UnityBuilder(container)

当我将 typesToScan 更改为

var typesToScan = new Type[]{};

该应用程序再次运行，但是当然，一旦我尝试将某些东西放在总线上，它就会失败，说它不知道通过扫描类型的类型。

任何人都知道在哪里查看或有此错误的经验？

检测到问题。我通过要扫描的类型添加的其中一条消息具有操作类型“CultureInfo”的属性，该属性不能很好地与序列化配合使用。

namespace InCityS.BL.Account.Messages
{
    public class CreateAccountCommand : ICommand
    {
        public string UserName { get; set; }
        public string Password { get; set; }

        public string FirstName { get; set; }
        public string LastName { get; set; }

        public CultureInfo Culture { get; set; }
    }
}

被替换为：

namespace InCityS.BL.Account.Messages
{
    public class CreateAccountCommand : ICommand
    {
        public string UserName { get; set; }
        public string Password { get; set; }

        public string FirstName { get; set; }
        public string LastName { get; set; }

        public string Culture { get; set; }
    }
 }
