哇！好的……我解决了我的 Wcf / Linq 错误（并且学到了很多东西——接下来会发布一系列博客文章）。现在我需要部署。我们在 Mosso / Rackspace 云上运行，目前该环境在部分信任环境中运行。

为了简单起见，我在 Wcf 服务中添加了一个几乎什么都不做的方法。

public string Echo(string what)
{
    return what;
}

我构建了这一切，并使用以下 Web.Config（仅相关部分）将其发送到测试服务器……是的，在公开危险方法之前，我显然需要添加安全性，但现在我只希望匿名的东西运行： )

<system.serviceModel>
 <bindings>
   <basicHttpBinding>
       <binding name="BasicAnonymous">
           <security mode="None"/>                
       </binding>
   </basicHttpBinding>
</bindings>
 <behaviors>
  <serviceBehaviors>
   <behavior name="FooBar.Backend.Web.Services.CoreDataWcfServiceBehavior">
    <serviceMetadata httpGetEnabled="true" />
    <serviceDebug includeExceptionDetailInFaults="true" />
   </behavior>
  </serviceBehaviors>
 </behaviors>
 <services>
  <service behaviorConfiguration="FooBar.Backend.Web.Services.CoreDataWcfServiceBehavior"
   name="FooBar.Backend.Web.Services.CoreDataWcfService">
   <endpoint address="" binding="basicHttpBinding" bindingConfiguration="BasicAnonymous" contract="FooBar.Backend.Web.Services.ICoreDataWcfService" />
   <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
  </service>
 </services>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true">
   <baseAddressPrefixFilters>
       <add prefix="http://backend.FooBar.com"/>
   </baseAddressPrefixFilters>
</serviceHostingEnvironment>
</system.serviceModel>

因此，我将使用控制台应用程序以最简单的方式调用它。我添加了服务参考，它添加得很好。然后我称之为（为简洁起见，我采用了非活动代码）......</p> 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text; 

using CoreWcfHarness.CoreDataServiceReference; 

namespace CoreWcfHarness
{
    class Program
    {
        static void Main(string[] args)
        {
            var context = new CoreDataWcfServiceClient(); 

            var echoval = context.Echo("Hello World!");
            Console.WriteLine(String.Format("{0}\n", echoval));
            Console.ReadKey();
        }
    }
}

和布拉莫。我遇到了一个例外。

System.ServiceModel.FaultException`1 was unhandled
  Message="Request failed."

  InnerException:

这很简单。任何熟悉中等信任环境和/或擅长堆栈跟踪的人？

谢谢！

“请求失败”可能是很多事情。

看起来最可能的原因是请求没有到达服务器。您应该检查服务器日志以确保将请求发送到正确的位置。
