次のすべてに一貫した名前空間 (http://somenamespace.com/2012/10/) を設定しました。

  1. サービス コントラクトの名前空間
  2. サービスの名前空間
  3. データ コントラクト名前空間
  4. バインディング名前空間

ただし、サービス ログ (.svclog) ファイルでこのエラーが発生します。誰かがこれについて私に教えてもらえますか? すでにいくつかのサイトに相談しましたが、役に立ちませんでした。

良いリファレンスは次のとおりです。

スタックトレースから判断すると、コントラクトのどこかに、特にPaymentType、PaymentTypeBaseの周りに派生クラスがあると思います。

最上位のDataContractをKnownType属性で装飾してみてください。これは、デシリアライザーが応答をデシリアライズするタイプを知るのに役立ちます。

「OOプリンシパルを扱う」が「サービスを扱う」というワームの缶を開けたばかりかもしれません。

どこかで、抽象クラスのどの具象を実際に使用するかについて「フィドルに支払う」必要があります。これは、サービスワイヤを通過します。

ここに1つのアプローチがあります:(これは具体的なものを理解するために反射を使用します）

http://ashgeek.blogspot.com/2011/02/wcf-serialization-dynamically-add.html

ここにもう1つあります:(これは具体的なものをリストするために小さなテキストファイルを使用します）

http://social.msdn.microsoft.com/Forums/en-US/wcf/thread/6b70e9f4-52bc-4fa9-a0ff-c0859e041e85/

結局のところ、サービスは具象のようであり、抽象クラスやインターフェースは好きではありません。

何年にもわたって、具体的な実装ではなく、インターフェース（または抽象クラス）にプログラムするように言われてきました。
