WCF的Web.Config - 複製服務名稱投擲的錯誤

Question

下面的代碼拋出

命名爲相同的密鑰「服務」子元素已經存在於相同的配置範圍的誤差。集合元素在相同的配置範圍內必須是唯一的（例如相同的application.config文件）。重複鍵值：'Marius.Marius_0_0_8'。

現在顯然有兩個名爲Marius.Marius_0_0_8的服務。但是，當我嘗試將其中一個名稱更改爲其他名稱時，我得到了一個不同的錯誤。我假設這是因爲該名稱必須與.svc中的名稱空間&類的名稱匹配。

我很累，一直盯着這幾個小時。我究竟做錯了什麼？我所要做的就是打開元數據，以便連接WCF測試客戶端。

Answer 1

您正試圖爲Mex端點聲明另一個服務。正確的方法是隻有一個暴露兩個端點的服務：真正的服務端點和wsdl端點。

<services> 
     <service name="Marius.Marius_0_0_8"> 
      <endpoint address="" behaviorConfiguration="Marius.MariusAspNetAjaxBehavior" 
       binding="webHttpBinding" contract="Marius.Marius_0_0_8" /> 

     <endpoint name="mex" 
       address="mex" 
       binding="mexHttpBinding" 
       contract="IMetadataExchange" /> 
     </service> 

    </services>
