ASP.NET WCF の単純な HelloWorld の例に取り組んでいます。サーバー側は正常に完了しましたが、クライアント側で作業中に問題が発生しています。SVCUTIL.exe を使用してプロキシ クラスを生成しました。

デバッグ時に次のエラーが発生します。

An exception of type 'System.InvalidOperationException' occurred in System.ServiceModel.dll but was not handled in user code

Additional information: Could not find endpoint element with name    'WSHttpBinding_IHelloWorldService' and contract 'IHelloWorldService' in the  ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this name could be found in the client element.

もう1つ、サーバーからdllファイルにアクセスしない場合、Channel Factoryを使用できますか?たとえば、WSDL URLリンクにアクセスできる場合

クライアント側 app.config

<system.serviceModel>
    <bindings>
        <wsHttpBinding>
            <binding name="WSHttpBinding_IHelloWorldService" />
            <binding name="WSHttpBinding_IHelloWorldServiceAsyn" />
        </wsHttpBinding>
    </bindings>
    <client>
        <endpoint address="http://localhost:8087/CreditUnionServices/HelloWorldServices/HelloWorldService"
            binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IHelloWorldService"
            contract="IHelloWorldService" name="WSHttpBinding_IHelloWorldService">
            <identity>
                <userPrincipalName value="DESKTOP-G6LE8I4\Khurram Zahid" />
            </identity>
        </endpoint>
        <endpoint address="http://localhost:8087/CreditUnionServices/HelloWorldServices/HelloWorldServiceAsyn"
            binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IHelloWorldServiceAsyn"
            contract="IHelloWorldServiceAsyn" name="WSHttpBinding_IHelloWorldServiceAsyn">
            <identity>
                <userPrincipalName value="xyz\abc" />
            </identity>
        </endpoint>
    </client>
</system.serviceModel>

クライアント プロキシ チャネル ファクトリ

 public class HelloWorldClient
{
    public string SendTestMessage(string name)
    {
        ChannelFactory<IHelloWorldService> _HelloWorldClientService = new ChannelFactory<IHelloWorldService>("WSHttpBinding_IHelloWorldService");

        IHelloWorldService _HelloWorldChannelService = _HelloWorldClientService.CreateChannel();

        var _returnMessage = _HelloWorldChannelService.GetMessage(name);

        ((IClientChannel)_HelloWorldChannelService).Close();

        return _returnMessage;
    }
}

サーバー側の設定ファイル

 <system.serviceModel>
<services>
  <service name="App.Services.Managers.HelloWorldManager" behaviorConfiguration="DefaultServiceBehavior">
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:8087/CreditUnionServices/HelloWorldServices"/>
      </baseAddresses>
    </host>
    <endpoint address="HelloWorldService" binding="wsHttpBinding" contract="App.Services.Contracts.IHelloWorldService"></endpoint>
    <endpoint address="HelloWorldServiceAsyn" binding="wsHttpBinding" contract="App.Services.Contracts.IHelloWorldServiceAsyn"></endpoint>
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="DefaultServiceBehavior">
      <serviceMetadata httpGetEnabled="True" httpsGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="False" />
    </behavior>
  </serviceBehaviors>
</behaviors>

コードの更新

public static class HelloWorldClient 
{
    public static string SendTestMessage(string name)
    {

        HelloWorldServiceClient _helloWorldService = new HelloWorldServiceClient("WSHttpBinding_IHelloWorldService");

        var _returnMessage =  _helloWorldService.GetMessage("mr kz ....");

        return _returnMessage;
    }
}
