服務發生錯誤ServiceHost僅支持類服務類型

Question

我試圖發佈服務並使其使用Windows身份驗證，當我嘗試發佈服務時出現錯誤，所以我沒有足夠多獲得提示輸入用戶名。

這是我的錯誤：

[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.Activation.ServiceHostFactory.CreateServiceHost(String constructorString, Uri[] baseAddresses) +530 
    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 

我研究這一百次，但我有發佈服務的經驗非常少。我一直在與他們合作，一旦他們建立從未發表過。

這是我的web.config，我已經從其他的web.config修改其中一個發佈罰款：

我沒有在我的web.release.config：

<?xml version="1.0"?>

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

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

</configuration> 

這是我的應用程序是什麼樣子：

一看到我在做什麼錯了？

Answer 1

錯誤表示您使用接口類型來構建主機而不是實現您的服務接口ISubService的類類型。

例如。

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

如果這是您的使用，將其更改爲使用實現的服務類類型的ISubService

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

如果配置在.SVC的服務，那麼：在您也

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

配置文件，更改服務名稱而不是服務合同的服務爲：

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