找不到ServiceHost指令中的WCF、服务属性值

我试图用IIS6托管我的服务，但我总是得到这个异常。

Version Information: Microsoft .NET Framework Version:2.0.50727.3082; ASP.NET Version:2.0.50727.3082 我完全没有线索，除了它似乎找不到我的程序集。代码应该使用公共类正确编译。
这是我的.svc文件：
<%@ ServiceHost Language="C#" Debug="true" Service="QS.DialogManager.Communication.IISHost.RecipientService" CodeBehind="RecipientService.svc.cs" %>我试着创建一个非常非常简单的服务，它也不包含任何东西，看看这是否可以工作，但仍然显示相同的老错误。

该问题也可能存在于svc文件中与svc.cs文件中不同命名空间中。
svc文件中的命名空间必须采用以下格式。
Service="Namespace.SvcClassName"Stack Overflow用户

我知道这可能是“显而易见”的答案，但它让我被绊倒了一点。确保bin文件夹中有项目的dll。当服务发布时，发布它的人删除了dll，因为他认为它们在GAC中。在本例中，专门用于项目(QS.DialogManager.Communication.IISHost.RecipientService.dll，的那个)不在那里。
同样的错误是由于非常不同的原因。

发生此错误的原因是.SVC文件中的服务名称不匹配。您可能已经更改了实现interface.The解决方案的服务类的名称，以便打开.SVC文件并与服务属性和CodeBehind属性完全匹配。因此，您的.SVC文件应该如下所示
<%@ ServiceHost Language="Language you are using" Debug="bool value to enable debugging" Service="Service class name that is implementing your Service interface" Codebehind="~/Appcode/Class implementing interface.cs"%>. for eg.
<%@ ServiceHost Language="C#" Debug="true" Service="Product.Service" CodeBehind="~/AppCode/Product.Service.cs"%>此示例用于使用C#语言、启用调试、服务类实现接口的.svc文件，该类位于名为Service.cs的app文件夹中，产品是服务类的命名空间。
另外，请在服务配置文件中进行相应的更改。
<system.serviceModel>
<services>
<service name="Product.Service" behaviorConfiguration="ServiceBehavior">
<endpoint address="" binding="wsHttpBinding" contract="Product.Iservice">
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<behavior name="ServiceBehavior">
<serviceMetaData httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</behaviors>
