听取“元素'行为'具有无效的子元素”应该被忽略,但由于它而无法更新服务引用

可能重复:
  The element ‘behavior’ has invalid child element ‘myFaultExtension’ in wcf app.config

我正在尝试实施Creating and Handling Faults in Silverlight。 (This项目在我的机器上运行。)

我收到Visual Studio警告:

  

元素'behavior'具有无效的子元素'betterErrorMessagesFaults'。

其他地方的其他答案说我应该忽略它,但我不能,因为我无法更新非.Web项目(包含所有xaml文件的项目)中的服务引用。当我尝试时,我收到此错误:

  

分析程序错误消息:无法加载为扩展名“betterErrorMessagesFaults”注册的类型“MyProject.Web.Services.BetterErrorMessagesFaultBehavior,MyProject.Web.Services,Version = 1.0.0.0,Culture = neutral,PublicKeyToken = null”。< / p>

这是Web.config的相关部分:

<system.serviceModel>
  <extensions>
    <behaviorExtensions>
      <add name="betterErrorMessagesFaults" 
        type="MyProject.Web.Services.BetterErrorMessagesFaultBehavior, MyProject.Web.Services, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>
    </behaviorExtensions>
  </extensions>
  <services>
    <service name="MyProject.Web.Services.Service2">
      <endpoint address="" binding="customBinding" 
          bindingConfiguration="MyProject.Web.Services.Service2.customBinding0" 
          contract="MyProject.Web.Services.Service2" 
          behaviorConfiguration="BetterErrorMessagesFaultBehavior"/>
      <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
    </service>
  </services>
  <behaviors>
    <serviceBehaviors>
      <behavior name="">
        <serviceMetadata httpGetEnabled="true" />
        <serviceDebug includeExceptionDetailInFaults="true" />
        <dataContractSerializer maxItemsInObjectGraph="2147483647" />
      </behavior>
    </serviceBehaviors>
    <endpointBehaviors>
      <behavior name="BetterErrorMessagesFaultBehavior">
        <betterErrorMessagesFaults/>
      </behavior>
    </endpointBehaviors>
  </behaviors>
  <bindings>
    <customBinding>
      <binding name="MyProject.Web.Services.Service2.customBinding0">
        <binaryMessageEncoding>
          <readerQuotas maxArrayLength="2147483647" maxBytesPerRead="2147483647" 
            maxDepth="2147483647" maxNameTableCharCount="2147483647" 
            maxStringContentLength="2147483647" />
        </binaryMessageEncoding>
        <httpTransport maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" 
            maxBufferSize="2147483647" />
      </binding>
    </customBinding>
  </bindings>
  <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
</system.serviceModel>

BetterErrorMessagesFaultBehavior只是课程here on MSDN的复制粘贴;只更改名称(我也尝试使用默认名称),并且命名空间更改为MyProject.Web.Services

我也尝试过交换

<add name="betterErrorMessagesFaults" 
    type="MyProject.Web.Services.BetterErrorMessagesFaultBehavior, MyProject.Web.Services, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>

<add name="betterErrorMessagesFaults" 
    type="MyProject.Web.Services.BetterErrorMessagesFaultBehavior, MyProject.Web.Services"/>

但没有效果。我读到这对空间等非常敏感,但我看不出任何问题。我也查看了AssemblyInfo,版本是1.0.0.0,文化只是空白(“”),我不知道PublicKeyToken是什么,但我怀疑这不是问题......

所以我很难过,不知道下一步该去哪儿。

可能迟到了一点点,但是您可以通过执行以下操作来验证您是否具有类型名称:

Console.WriteLine(typeof(BetterErrorMessagesFaultBehavior).AssemblyQualifiedName);

那应该包含PublicKeyToken部分供您比较......
