クラス転送の[KnownType]の問題を解決した後：WCFを介してクラスオブジェクトの配列またはリストを提供する

svcutilを使用してプロトコルを生成しようとすると、これが発生します。

だから私はアプリケーションタイプを設定する必要があると思います

application / soap + xml; charset = utf-8

しかし、それでも私はそれを作る方法を理解することができません。

現在のWCFホストを作成する方法は次のとおりです。

private void createHost() {
    /// Create the ServiceHost.
    using (ServiceHost host = new ServiceHost(typeof(NEN), baseAddress)) {
        /// Enable metadata publishing.
        ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
        smb.HttpGetEnabled = true;
        smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
        host.Description.Behaviors.Add(smb);

メタデータを公開するには、Metadata Exchange エンドポイントを追加する必要があります

/// Create the ServiceHost.
using (ServiceHost host = new ServiceHost(typeof(NEN), baseAddress)) {
    /// Enable metadata publishing.
    ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
    smb.HttpGetEnabled = true;
    smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
    host.Description.Behaviors.Add(smb);

// Add MEX endpoint
  host.AddServiceEndpoint(
  ServiceMetadataBehavior.MexContractName,
  MetadataExchangeBindings.CreateMexHttpBinding(),
  "mex");

ServiceMetadataBehavior を追加するだけでなく、メタデータ交換エンドポイントも追加する必要があります。
