In my wcf project, I can see several operationcontracts
I do not see the new one I have just added i.e.
inside the interface class:
...
...
...
[OperationContract]
void WriteAllSQL(string strXML);
in the .svc.cs file
...
...
...
public void WriteAllSQL(string strXML)
{
...
...
}
On the client, when I create an instance to the wcf, I only see the previous operationcontracts and not the new ones.
Have i not done something correctly?
Hey,
Try updating the Service Reference within your client project.
Gary
This is what is surprizing. I have updated the references many times. but in th esolution, the silverlight app does not see the new method in wcf.
BUT, using the wcf test client tool, it does see it.
In which case, try removing the service reference, and re-add it.
Gary
still the same problem.
Were there any warnings, or errors while the Service Reference was being created?
Certains DataTypes are not supported in Silverlight, and I have seen the methods that use them not appear in the Service Reference.
Gary
No warning.
And even if I add any new methods, they will not be shown.
Ok, so to clarify...
You have a WCF Endpoint that exposed some methods. You created the Service Reference initially, and could see the methods. Now, you have added some new methods, but even though you update the service reference, you can't see these new methods. However, if you use the WCF Test Client, you can see all the methods.
Does that pretty much sum up where you are?
Gary
That is correct.
As an extra test, I added a new .svc and added two public methods. and then republished the wcf into the virtual directory, etc...
The wcf test client.exe can see the new methods inside the new .svc whereas the methods can not be seen inside the silverlight app project aftering doing the usual add service reference, etc.
Can you show the definition of one of the methods that isn't working? What are the DataTypes that you are using?
public void WriteToXML(string strXML)
{
try
{
Utilities.logfile("Begin WriteXML");
}
catch (Exception ex)
{
Utilities.logfile("error : ");
}
}
Only th eold methods are shown.
Somehow the new methods are blocked fom being shown.
Could this be to do with security/permission settings that may have been changed ? (Nothing that I know of has been changed).
Hey,
I am really not sure what else to suggest at this point.
Is it possible that you can upload your project somewhere so that I can take a look?
Gary
Do you think th eproblem is the silverlight application project not being able to see the wcf properly?
It seems the wcf side is ok, since the wcf test client.exe does indeed see all the methods in wcf.
This is what I am not sure of.
It certainly looks like it is the Silverlight side of things that is causing the problem, but I am really not sure what could be wrong.
Gary
I now created a brand new solution with silverlight project. added servicesreferences to point to the existing wcf. Still does not see the new methods and it even doe snot see any methods within any new .svc files.
gary,
Could this be to do with port number on my machine?
<endpoint address="http://localhost:1841/DM.svc"
binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IDM"
contract="FMService.IDM" name="BasicHttpBinding_IDM" />
Hey,
I don't see how that could be making some things come through, but then stopping others.
Gary
I even did clean and then build.
No difference.
Have been doing extra checks...Quote:

Created a new solution with new silverlight application project as well as new wcf project.
the silverlight pages do see the new .svc files and their methods...
Still not sure what the problem is in that silverlight app.
Gary,
Still looking at this issue, and so trie again by adding a new .svc to the wcf project. Then in silverlight project, in addingservices... ths following error is shown when usingthe new service. can you see if there is something that can show what the problem is please?
There was an error downloading 'http://localhost:1841/AnotherService.svc'.
The request failed with the error message:

Metadata contains a reference that cannot be resolved: 'http://localhost:1841/AnotherService.svc'.
The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.
If the service is defined in the current solution, try building the solution and adding the service reference again.
Gary,
Could this be to do with namespaces?
Everytime I add a new .svc file the namespace becomes FService but I have changed the namespaces for all the files. ?
Hey,
I don't think you should need to alter the namespaces at all, this is not something that I have ever had to the do. The proxy class that gets created for the service reference is based on the name that you first give it when you add the service reference.
Is it possible that you can upload your sample project so that I can take a look, along with steps to reproduce the problem that you are having?
Gary
The problem was solved by creating a new wcf project.
Thank you for your time Gary
Hey,
Glad to hear that you got it sorted out. Still don't have an explanation as to what happened though :(
Gary
Me neither.
Hope I do not have to go through that again.
Thanks again.
