2.0 framework calling WCF service

G

Greg

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!

As far as contacting WCF services, there is no problem. It is merely a WSDL
endpoint (technically more, but you can create the "web" reference to a WCF
service). The only potential gotcha I can think of right now is if you are
using of the new encoding methods. If you are using SOAP, you should be
fine.

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>

I have been able to consume this WCF service as long as the binding is set to
BasicHTTP.

What do i need to do to consume the WCF service with the bindings set to
wsHttpBinding. (i have WS 3.0 installed)
If you can point me to some codesamples this would be appreciated.

This could be a disparity between the Microsoft world and Oracle, based on
the objects you are talking about. Oracle TechNet might have some options,
as might support.microsoft.com. Neither is extremely good at helping the
other, however, so I am not sure how much this will yield. Will see if I
find anything.
