问题描述：
我正在.NET4.5 WPF应用程序中工作。我收到了App.xml行<desktop1:ReactiveBootstrapper x:Key="bootstrapper" />中显示的特殊异常，我认为这与添加新的Web服务方法有关。序列不包含任何元素，Castle.Facilities.WcfIntegration.WcfClientExtension.ObtainServiceContract

它吹ü在this.Start();上的Reactive bootstrapper构造函数中，我无法进一步介绍。
public class ReactiveBootstrapper : BootstrapperBase {
public ReactiveBootstrapper()
{
this.Log.Info("Starting bootstrapper");
this.Start();
}
}
BootstrapperBase为Caliburn.Micro我假设的东西炸毁了依赖注入。
有没有人遇到过这个错误，并知道这里发生了什么？或者有想法如何进一步调试？，我相信异常开始出现后向Web服务添加额外的方法，但我不是100％确定。如果你需要更多的信息，只需要问。
答
事实证明，我将没有支持Web服务的Interface添加到所有Web服务接口被保留的'错误'文件夹中。
public static void RegisterWcfServices()
{
Container.Register(
Types.FromAssemblyContaining<ITransactionService>()
.InSameNamespaceAs<ITransactionService>()
.Configure(
x =>
x.Named(x.Implementation.Name)
.AsWcfClient(
new DefaultClientModel
{
Endpoint =
WcfEndpoint.BoundTo(new WSHttpBinding(SecurityMode.Transport) { MaxReceivedMessageSize = int.MaxValue })
.At(string.Format("https://{0}/{1}.svc", GetServerName(), x.Name.Substring(1)))
})
.IsFallback()));
}
上面的机制然后拿起接口，因为没有WebService支持它爆炸。
*序列不包含任何元素*这意味着某些IEnumerable/collection是空的，但它不应该如此。当您在空IEnumerable上使用First（）时，也会引发这种异常。虽然我不熟悉其他涉及的代码。 – 2014-10-09 16:15:24
@KingKing在这种情况下，它是'Single（）'，因为您可以从内部StarckTrace顶部的堆栈跟踪中看到，无论如何。我在这里有点绝望，所以任何形式的帮助都非常感谢。 – 2014-10-09 16:45:45
