出于某种原因,我无法克服这个错误.我已经完成了搜索,但找不到任何vb示例.这个web.config我做错了什么？

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
