    using System.Runtime.Serialization;
    using System.ServiceModel;
    using System.Text;
    using System.ServiceModel.Activation;
    namespace YBS.Services.SYS
      // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "ProcessLog" in both code and config file together.
      [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
      public class ProcessLog : IProcessLog
        public void GetLogData(string sTimeStamp)

    I was using WCF Service Library and I changed it to WCF Service application.
    Now the error changed to 'No Transport'.


    Telerik: is it possible to provide an example with WCF Service from an WCF Service Application??

    I'm receiving an 'WCF WebHttp Service returns HTTP 415 “Unsupported Media Type”' error when adding a service reference to my WCF Services application using the following web.config
    <?xml version="1.0"?>
        <compilation debug="true" targetFramework="4.0" />
            <behavior name="ProcessLogBehavior">
            <behavior name="ProcessLogBehavior">
              <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
              <serviceMetadata httpGetEnabled="true"/>
              <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
              <serviceDebug includeExceptionDetailInFaults="true"/>
          <service behaviorConfiguration="ProcessLogBehavior" name="ProcessLog">

    A webservice defined in this way cannot be accessed via JavaScript. It needs an object in the code-behind, which is not available in this case. What I would advise is that you examine the live demos folder to see how the supported scenario is implemented - an svc file pointing to a class in the App_Code folder. In the same manner a regular WebService can be used. These approaches are shown in this demo for WCF and in this one for the regular WebService. I believe you may also find interesting the Callback update approach, as it is also a lightweight solution for updating content. With it you could also implement custom logic in the code-behind to access services you need to. As long as they return a proper string you can easily feed it to the RadNotification.
