やあ、

次のバインド構成を持つ IIS でホストされている WCF サービスがあります。

 <binding name="netTcpRegular" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:00:20" sendTimeout="00:20:00" transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions" hostNameComparisonMode="StrongWildcard" listenBacklog="10" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxConnections="10" maxReceivedMessageSize="2147483647">
          <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/>
          <reliableSession ordered="true" inactivityTimeout="infinite" enabled="false"/>
          <security mode="None">
            <transport clientCredentialType="None" />
          </security>
        </binding>

クライアント (チャネルを開いたままにしている) が WCF サービスにログインすると、チャネルは 20 秒後にエラー例外をスローし、サービスと通信することさえせず、まったく何もしていませんか? SO 20 秒間非アクティブ状態が続くと、通信は失敗します。

receiveTimeout は、通話が進行中の場合にのみ影響するはずですよね? では、チャネルを開いてサービス呼び出しを行う準備ができているだけで、何もしていないときにタイムアウトになるのはなぜでしょうか?

WCF ログを使用すると、次の例外が発生します。

ReceiveTimeout の意味を誤解しています。これは、「接続が切断される前に、アプリケーション メッセージが受信されない間、接続が非アクティブなままでいられる時間間隔」です。これを無限に拡張するには、信頼できるセッションを有効にする必要があります。これで解決することを願っています。

編集： ここに詳細な説明があります。あなたが求めているプロパティはsendtimeoutだと思います

受信タイムアウトは、すべてのデータが受信されるまで待機する時間です。

チャネルが開くとすぐに時間が開始され、送信した最初のバイトが検出されず、タイマーが開始されます。

乗った時ではなく、手を振った時にメーターが動くタクシーのようなものです。
