「ServiceHost僅支持類服務類型」

由於某種原因，我無法通過此錯誤。我已經完成搜索，但找不到任何vb示例。我在做這個web.config錯了什麼？「ServiceHost僅支持類服務類型」

SalesTracking.svc

<%@ ServiceHost Language="VB" Debug="true" Service="SalesTracking.ISalesTracking" CodeBehind="SalesTracking.svc.vb" %>

SalesTracking.svc.vb

Imports GlobalDir 
Imports System.Web.Script.Serialization 
Imports System.Reflection 
Imports System.Data.SqlClient 
Imports System.Web.Configuration 
Imports System.Threading 
Imports System.ServiceModel.Activation 


<AspNetCompatibilityRequirements(RequirementsMode:=AspNetCompatibilityRequirementsMode.Allowed)> _ 
Public Class WebService 
    Implements ISalesTracking 



    Public Function GetDataUsingDataContract(ByVal composite As ClientSideData) As ClientSideData Implements ISalesTracking.GetDataUsingDataContract 

    End Function 
End Class

的Web.config

我編輯了您的標題。請參閱：「[應該在其標題中包含」標籤「]（http://meta.stackexchange.com/questions/19190/）」，其中的共識是「不，他們不應該」。 –

Service屬性必須是實現的，而不是接口。

<%@ ServiceHost Language="VB" Debug="true" Service="SalesTracking.WebService" ....

謝謝先生！ – atrueresistance

當我重命名服務時，這個問題剛剛發生在我身上。顯然，dident會影響svc文件，所以在改變之後就像你說的那樣，它像一個魅力:)。 – JensB

謝謝你..我爲我工作.... –
