このSilverlightデュプレックスを機能させるために何時間も戦っていますが、失敗に次ぐ失敗、

A) WCF Service Appllication B) WPF Client C) Silverlight Client (+host は必要ですか?!)

A<=>B に正常に接続しました - 正常に動作しています。私の問題は A<=>C (Silverlight Duplex Client) です。

  • どういうわけか2つのエンドポイントを持つことはできますか? wsDualHttpBinding & pollingDuplexHttpBinding ? 試して失敗

コントラクト 'Service2.IService1' のエンドポイント構成セクションを読み込めませんでした。そのコントラクトの複数のエンドポイント構成が見つかったためです。優先エンドポイント構成セクションを名前で示してください。

  • pollingDuplexHttpBinding は WPF で動作しますか?

  • ヘルプ ！ありがとう ！

はい、2つ以上のエンドポイントが可能です:

ステップ I :

<endpoint address="wsDualHttpBinding" 
                  binding="wsDualHttpBinding" 
                  bindingConfiguration="wsDualHttpBinding" 
                  contract="TheWCFService.IService1">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>

        <endpoint 
          address="mex"
          binding="mexHttpBinding" 
          bindingConfiguration="" 
          contract="IMetadataExchange" />

        <endpoint
           address="pollingDuplexHttpBinding"
           binding="pollingDuplexHttpBinding"
           bindingConfiguration="multipleMessagesPerPollPollingDuplexHttpBinding"
           contract="TheWCFService.IService1">
        </endpoint>

        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8732/Service1/" />
          </baseAddresses>
        </host>

ステップ II : 非常に重要: WCF Cross Domain SecurityException

http://www.itscodingtime.com/post/Silverlight-to-WCF-Cross-Domain-SecurityException.aspx

ステップ III :

シルバーライト クライアント:

            var x = new WCFService.Service1Client(
                    new PollingDuplexHttpBinding { DuplexMode = PollingDuplexMode.MultipleMessagesPerPoll, },
                    new EndpointAddress(@"http://localhost:59732/Service1.svc/pollingDuplexHttpBinding")
                    );

WPF クライアント:

>  _objProxy = new Service1Client(new InstanceContext(this),
> "WSDualHttpBinding_IService1");
