本文介绍了类型'RestService.weddingservice'，因为在ServiceHost的指令中的服务属性值提供找不到的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我试着去创造我的第一个WCF RESTful服务。
在VS2010我打开weddingservice.svc，然后按F5键。浏览器中打开
但是，这是我得到的错误：

 在'/'应用程序的服务器错误。类型'RestService.weddingservice，作为服务提供的属性在ServiceHost的指令值，或在配置元素system.serviceModel / serviceHostingEnvironment / serviceActivati​​ons提供找不到。说明：执行当前Web请求的执行过程中发生未处理的异常。请查看有关错误的详细信息的堆栈跟踪以及它起源于code。异常详细信息：System.InvalidOperationException：类型RestService.weddingservice，作为服务提供的属性在ServiceHost的指令值，或在配置元素system.serviceModel / serviceHostingEnvironment / serviceActivati​​ons提供找不到。源错误：当前Web请求的执行过程中生成了未处理的异常。有关异常的来源和位置信息可以使用异常堆栈跟踪下面确定。堆栈跟踪：

下面我code，我希望有人能够看到什么即时通讯做错了。难道我没有使用正确的URI？我错过了什么？

和尝试再次运行过程

Im trying to create my first WCF restful service. In VS2010 I open weddingservice.svc and then hit F5. A browser opens to http://localhost:50043/weddingservice.svcBut there, this is the error I get:

Below my code, I hope anyone is able to see what Im doing wrong. Am I not using the correct URI? What did I miss?

weddingservice.svc

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

Iweddingservice.vb

Imports System.ServiceModel
Imports System.Web
Imports System.IO
Imports System.Runtime.Remoting.Activation
Imports System.Collections.Generic

Namespace RestService
<ServiceContract()>
Public Interface Iweddingservice

    <OperationContract()> _
<Web.WebGet(UriTemplate:="job/{name}")> _
    Function DoJob(name As String) As String

End Interface
End Namespace

        Implements Iweddingservice

        Public Function DoJob(name As String) As String Implements Iweddingservice.DoJob
            Return String.Format("Hello, {0}", name)
        End Function
    End Class
End Namespace

web.config

<system.serviceModel>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  <services>
    <service name="weddingservice">

    </service>
  </services>
<behaviors>
  <serviceBehaviors>

  </serviceBehaviors>
  <endpointBehaviors>
    <behavior name="webHttp">
      <webHttp/>
    </behavior>
  </endpointBehaviors>
</behaviors>
</system.serviceModel>
解决方案

Set the 

<serviceDebug includeExceptionDetailInFaults="false" />

to 

<serviceDebug includeExceptionDetailInFaults="true" />

in order to get more details

and try to run the process again
