2.0 Framework calling WCF service.

    I have just created a WCF service that is using WShttpbasic and all is good
    when another .net 3.0 application consumes it. However, I have legacy apps
    that must use this service and are running on .net 2.0 and are housed on
    Windows 2000 servers.

    I have been unable to find ANY info on how to do this, or if it is even
    possible.
    I find it hard to believe that WCF would not be able to be consumed by 2.0
    applications.

    Please help!

    Hi,

    are you able to get the WSDL exposed by the service? If your service is on
    local IIS say service.svc try putting http://localhost/service.svc?wsdl

    If not, adding ?wsdl to the url should expose it, and you should be able to
    use that to reference the service from legacy side.

    I am able to add the web reference to the project; however when I try to
    implement it all that I have to choose from is the Cass object, Interface,
    eventargs, and eventhandler.
    Example:
    OracleService.BasicEmployee;
    OracleService.GetFullEmployeeByEmployeeIDCompletedEventArgs;
    OracleService.GetFullEmployeeByEmployeeIDCompletedEventHandler;
    OracleService.WSHttpBinding_IBasicEmployee
    (Service = web reference)

    In testing I have tried using Service.WSHttpBinding_IBasicEmployee , However
    I just get a time out message.
    Example:
    OracleService.WSHttpBinding_IBasicEmployee proxy = new
    WSETesting.OracleService.WSHttpBinding_IBasicEmployee();
    OracleService.BasicEmployee[] arrayemployee =
    proxy.GetEmployeeByEmployeeID("12356987");
    OracleService.BasicEmployee;
    OracleService.GetFullEmployeeByEmployeeIDCompletedEventArgs;
    OracleService.GetFullEmployeeByEmployeeIDCompletedEventHandler;
    OracleService.WSHttpBinding_IBasicEmployee
    foreach (OracleService.BasicEmployee emp in arrayemployee)
    {
    string me = emp.FirstName;
    }

    I have also tried to run the wsdl.exe I received the following error:

    Also, here are the bindings stated in the web config of the WCF service.
    <service name="OracleService" behaviorConfiguration="returnFaults">
    <endpoint contract="OracleServices.OracleContracts.IBasicEmployee"
    binding="wsHttpBinding"/>
    <endpoint
    contract="OracleServices.OracleContracts.IBasicEmployeeEmploymentStatus"
    binding="wsHttpBinding"/>
    <endpoint
    contract="OracleServices.OracleContracts.IBasicEmployeePersonalAddress"
    binding="wsHttpBinding"/>
    <endpoint
    contract="OracleServices.OracleContracts.IEmployeeLocations"
    binding="wsHttpBinding"/>
    <endpoint
    contract="OracleServices.OracleContracts.ILinkOracleMessage"
    binding="wsHttpBinding"/>
    </service>
