WCF错误：远程服务器返回错误：未找到

问题描述

在我的网站上，我有一个使用WCF服务的silverlight应用程序。通常，一切正常，但是如果我让页面处于非活动状态一段时间，然后单击其中一个按钮，我会收到以下错误：

System.ServiceModel.CommunicationException：远程服务器返回了错误：未找到

这是我的错误发生的代码（错误发生在方法中的第二行代码中（包含_result =（（MyApp.MyAppService .....） ）：

On my website, I have a silverlight app that utilizes a WCF service. Normally, everything works fine however if I leave the page inactive for a little while, and then click one of the buttons, I get the following error:
System.ServiceModel.CommunicationException: The remote server returned an error: Not Found
Here's the code where my error's occuring (the error occurs on the 2nd line of code within the method(the line that contains "_result = ((MyApp.MyAppService....." ) :

<br />
public MyApp.MyAppService.AccountSilverlight EndGetAccount(System.IAsyncResult result) <br />
{<br />
object[] _args = new object[0];<br />
MyApp.MyAppService.AccountSilverlight _result = ((MyApp.MyAppService.AccountSilverlight)(base.EndInvoke("GetAccount", _args, result)));<br />
                return _result;<br />
}<br />

知道为什么会这样吗？



谢谢。

Any idea why this may be happening?

Thanks.

推荐答案

<system.diagnostics>
    <sources>
      <source name="System.ServiceModel"

              switchValue="Information, ActivityTracing"

              propagateActivity="true">
        <listeners>
          <add name="traceListener"

              type="System.Diagnostics.XmlWriterTraceListener"

              initializeData= "D:\Sumit.svclog"/>
        </listeners>
      </source>
    </sources>
  </system.diagnostics>

这将生成.svc，分析它将提供的文件你有很多信息。



2）你可以使用外部工具来分析wcf服务调用，比如fiddler。在这种情况下，还尝试分析服务调用

this will generate an .svc, analyse this file it will provide you with a lot of information.

2) U can use external tools for analysing the wcf service calls, such as fiddler. In this case also try to analyse the service calls

<system.servicemodel>
    <client>
      <endpoint address="ENDPOINT Address">
        (other stuff)
      </endpoint></client></system.servicemodel>
