我正在尝试发布一项服务并让它使用 Windows 身份验证，当我什至尝试发布它时出现错误，所以我还没有得到足够的提示输入用户名。

这是我的错误：

[ArgumentException: ServiceHost only supports class service types.]
   System.ServiceModel.Description.ServiceDescription.GetService(Type serviceType) +16602430
   System.ServiceModel.ServiceHost.CreateDescription(IDictionary`2& implementedContracts) +80
   System.ServiceModel.ServiceHostBase.InitializeDescription(UriSchemeKeyedCollection baseAddresses) +174
   System.ServiceModel.ServiceHost..ctor(Type serviceType, Uri[] baseAddresses) +475
   System.ServiceModel.Activation.ServiceHostFactory.CreateServiceHost(Type serviceType, Uri[] baseAddresses) +43

   System.ServiceModel.HostingManager.CreateService(String normalizedVirtualPath) +1413
   System.ServiceModel.HostingManager.ActivateService(String normalizedVirtualPath) +50
   System.ServiceModel.HostingManager.EnsureServiceAvailable(String normalizedVirtualPath) +1172

[ServiceActivationException: The service '/subservice/ISubService.svc' cannot be activated due to an exception during compilation.  The exception message is: ServiceHost only supports class service types..]
   System.Runtime.AsyncResult.End(IAsyncResult result) +901424
   System.ServiceModel.Activation.HostedHttpRequestAsyncResult.End(IAsyncResult result) +178638
   System.Web.CallHandlerExecutionStep.OnAsyncHandlerCompletion(IAsyncResult ar) +136

我已经对此进行了一百次研究，但我对发布服务的经验很少。一旦它们建成，我就与他们合作过，只是从未发布过。

这是我从另一个发布良好的 web.config 修改的 web.config：

我的 web.release.config 中没有任何内容：

<?xml version="1.0"?>

<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">

  <system.web>
    <compilation xdt:Transform="RemoveAttributes(debug)" />
  </system.web>

</configuration>

这是我的应用程序的样子：

有人看到我做错了什么吗？

该错误表明您正在使用 Interface 类型来构造一个主机，而不是实现您的服务接口的类类型ISubService。

例如。

ServiceHost host = new ServiceHost(
                       typeof(subservice.ISubService), new Uri("someuri"));

如果这是您的用法，请将其更改为使用已实现的服务类类型ISubService

ServiceHost host = new ServiceHost(
                       typeof(subservice.SubService), new Uri("someuri"));

如果在 .svc 中配置服务，则：

<%@ServiceHost Service="subservice.SubService"%>

同样在您的配置文件中，将服务名称更改为服务而不是服务合同：

   <services>
          <service name="subservice.SubService">
          ...
