Fiddler 2 を使用して POST すると失敗する単純な REST サービス エンドポイントがあります。入力パラメーターを必要としないエンドポイントは成功します。データを渡すだけでは失敗します。VS 2010 に統合された Web サーバーを使用しています。

詳細：

Global.asax エントリ: 

private void Application_Start(object sender, EventArgs e)
        {
            RegisterRoutes();
        }
    private void RegisterRoutes()
        {
            RouteTable.Routes.Add(new ServiceRoute("Employee", new WebServiceHostFactory(), typeof(Employee)));
            RouteTable.Routes.Add(new ServiceRoute("Provider", new WebServiceHostFactory(), typeof(Provider)));
        }

ウェブサービス： 

[ServiceContract]
        [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
        [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
        public class Provider : BaseMvpWebService<ProviderPresenter>, IProvider

    [WebInvoke(Method="POST", RequestFormat=WebMessageFormat.Json, UriTemplate="",      ResponseFormat=WebMessageFormat.Json, BodyStyle=WebMessageBodyStyle.Wrapped)]
        public ProviderListWrap FilteredList(GeneralSearchView filtersearch)
    { ... }

コンテンツ タイプのスラッシュに構文上の問題があるのではないかと考えています。試す：

コンテンツ タイプ: アプリケーション/json

そうでない場合、応答に他の詳細はありますか? ちょうど 400 の悪い要求ですか？
