c# - netpeertcpbindingはリクエスト/リプライをサポートしていますか

Question

一方向の会話で正常に動作しているWCFp2pメッシュネットワークがあります。2つの数値を加算して、合計を返すメソッドを呼び出すことが可能かどうかを調査しています。

ただし、接続しようとするとエラーが発生します。

コントラクトには要求/応答が必要ですが、バインディング'NetPeerTcpBinding'はそれをサポートしていないか、サポートするように適切に構成されていません。

      participant = factory.CreateChannel();

      // Retrieve the PeerNode associated with the participant and register for online/offline events
