• Re: Ajax enabled WCF Service stops working with Undefined error

  For example,if you write javascript code in two or more .js files(not in the html file). wcf functions are call in these .js files.Then you can include both the scripts and wcf services like below: <asp:ScriptManager ID="ScriptManager1" runat="server" > <Scripts> <asp:ScriptReference Path="../JavaScript/public.js" /> <asp:ScriptReference Path="../JavaScript/Js_Monitor/monitor_alarm.js" /> <asp:ScriptReference Path="../WCF/wcfMonitor

  There is a bug when you include WCF service in this way: <asp:ScriptManager ID="ScriptManager1" runat="server"> <services> <asp:servicereference Path="CostService.svc" /> </services> </asp:ScriptManager> especially then WCF service is used in diffrent pages. Because the JavaScripts may be load faster then WCF services. Try to include your WCF service like this: <asp:ScriptManager ID="ScriptManager1" runat="server">

  It may be the free memory is too low,kill some useless processes to get more.The default minimum free memory percentage is 5.You can change it in the config file like below: <serviceHostingEnvironment aspNetCompatibilityEnabled="true" minFreeMemoryPercentageToActivateService="1"/> If you set that percentage up to 99,than 'Undefined' error will be reported again again and again.And if it happen,you can open the wcf(.svc) file in IIS.Than will show you the error details
