Question

我正在尝试开发一个WCF服务，用作来自提供商的已定义Web服务的代理。

以下是我为实现这一目标而采取的步骤：

创建WCF服务应用程序
添加了对提供者Web服务的服务引用
在项目中添加了Global.asax。
通过NuGet向项目添加了Castle.Core（v3.2）引用。
在Global.asax

以下是我Global.asax

/// <summary>
/// Contiene eventos globales ejecutados 
/// </summary>
public class Global : HttpApplication
{

    private static readonly ProxyGenerator generator = new ProxyGenerator();

    private static List<object> proxies = new List<object>();

    /// <summary>
    /// Evento que se ejecuta cuando se inicializa la aplicacion
    /// </summary>
    /// <param name="sender">Objeto que origna el evento</param>
    /// <param name="e">Argumentos del evento</param>
    protected void Application_Start(object sender, EventArgs e)
    {
        ConfigurarServicios();
    }

    /// <summary>
    /// Busca los servicios registrados en el proyecto
    /// </summary>
    /// <returns>Coleccion de servicios registrados y que extienden
    /// la clase ServiceBase</returns>
    private static IEnumerable<Type> BuscarServicios()
    {
        ConfigurarProxies();

        var list = new List<Type>();

        foreach (var proxy in proxies)
        {
            list.Add(proxy.GetType());
        }

        return list;
    }

    /// <summary>
    /// Configura los servicios del proyecto para ser accedidos
    /// a traves de REST y SOAP
    /// </summary>
    private static void ConfigurarServicios()
    {
        var soapFactory = new ServiceHostFactory();

        var services = BuscarServicios();
        foreach (var serviceType in services)
        {
            string serviceName = "xm";

            var soapEndpoint = new ServiceRoute("Servicios/" + serviceName, soapFactory, serviceType);


            RouteTable.Routes.Add("Servicios/" + serviceName,soapEndpoint);

        }
    }

    private static void ConfigurarProxies()
    {
        var interceptor = new Interceptor(); 

        var proxy1 = generator.CreateInterfaceProxyWithoutTarget(typeof(ExternalServices.XpressMoney.XMSendTxnServicePortType), interceptor);


        proxies.Add(proxy1);
    }
}

当我运行项目时，一切正常，但当我尝试访问ServiceRoute / Servicios / xm时，它会显示下一个错误：

The type 'Castle.Proxies.XMSendTxnServicePortTypeProxy, DynamicProxyGenAssembly2, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null', provided as the Service attribute value in the ServiceHost directive, or provided in the configuration element system.serviceModel/serviceHostingEnvironment/serviceActivations could not be found.

这就是堆栈：

   System.Web.CallHandlerExecutionStep.OnAsyncHandlerCompletion(IAsyncResult ar) +129

我想当.NET Framework尝试动态实例化DynamicProxy时会出现问题，但我真的不知道。也许Next Lines是一个线索：

var soapEndpoint = new ServiceRoute("Servicios/" + serviceName, soapFactory, serviceType);

RouteTable.Routes.Add("Servicios/" + serviceName,soapEndpoint);

希望你能帮助我。

在运行时找不到DynamicProxy即服务
