System.InvalidOperationException: WebServiceBindingAttribute is required on proxy classes.

[Joseph Geretz]

System.InvalidOperationException: WebServiceBindingAttribute is required on
proxy classes.

My environment: Visual Studio 2005, targeting FX 2.0; I've developed a Web
Service which uses DIME to transfer file attachments to and from the server.
I'm using WSE 2.0 SP3 which is supposed to support FX 2.0, as far as I know.
(We will soon move on to MTOM, however I'm stuck with DIME for now; the
solution was originally written for FX 1.1, and I need to remain with WSE
and DIME until I can complete the migration to MTOM.)

I'm getting the following error on my first method call into the Web Service
(via the client's Proxy class):

---------------------------------------------
An unhandled exception of type 'System.Web.Services.Protocols.SoapException'
occurred in System.Web.Services.dll

Additional information: System.Web.Services.Protocols.SoapException: Server
was unable to process request. ---System.InvalidOperationException:
WebServiceBindingAttribute is required on proxy classes.
at System.Web.Services.Protocols.SoapClientType..ctor (Type type)
at System.Web.Services.Protocols.SoapHttpClientProtoc ol..ctor()
at Microsoft.Web.Services2.WebServicesClientProtocol. .ctor()
at SRSFreedom.Repository..ctor() in C:\VBProjects\SRSDev\Source Code\WSL
Components\Repository.asmx.cs:line 30
--- End of inner exception stack trace ---

In order to diagnose this, I created a brand new driver project, a very
simple WinForm project to simply create an instance of the Web Service and
call a single method. The proxy is absolutely untouched since it was
generated automatically by VS 2005 when I referenced the Web Service.

Here are the attributes which decorate the definition of the Proxy class:

[System.CodeDom.Compiler.GeneratedCodeAttribute("Sy stem.Web.Services",
"2.0.50727.42")]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("c ode")]
[System.Web.Services.WebServiceBindingAttribute(Nam e="RepositorySoap",
Namespace="http://srssoft.com/webservices/")]
public partial class Repository :
System.Web.Services.Protocols.SoapHttpClientProtoc ol { ...

The WebServiceBinding attribute *IS* specified, so what is the runtime
complaining about?

Can anyone help straighten this out for me?

Thanks!

Well knock me down - Is that the correct error message????

System.InvalidOperationException: WebServiceBindingAttribute is required
on proxy classes.

After fiddling around for hours, in desperation, just for the kick of it, I
inserted this attribute into the declaration of the Web Service itself (i.e.
the asmx page). So here's what it looks like now:

[WebService(Namespace="http://srssoft.com/webservices/")]
[System.Web.Services.WebServiceBindingAttribute(Nam e = "RepositorySoap",
Namespace = "http://srssoft.com/webservices/")]
public class Repository : Microsoft.Web.Services2.WebServicesClientProtocol
// System.Web.Services.Protocols.SoapHttpClientProtoc ol
{...

BINGO! Everything starts working again. (WOW - just like it did under FX
1.1. :-\ )

So the point wasn't that the attribute was missing on the client Proxy, but
rather the attribute was missing on the Web Service itself! Nothing like a
well defined error message to shed some light on the problem.

Well I hope this helps the next guy who decides to migrate a WSE Web Service
from FX 1.1 to 2.0. If my experience is any indicator - it's not going to be
painless.

Well, I'm further along, but this is still not working.

At least I'm now able to trace into the Web Service methods, however, on the
server, the following statement returns a null object reference.

SoapContext RespContext = SoapContext.Current;

So why is this object null? How do I send a response back to the client?

Looking into this a bit further, I see my Web Service class defined as
inheriting from base class
Microsoft.Web.Services2.WebServicesClientProtocol. Is this correct? I guess
this is the correct definition for the client, but how about for the server?
I wish I could find a WebServices*Server*Protocol class to inherit from but
I just can't find this. Can you tell me what is the correct base class for
my Web Service class on the server and what object I use to send back a
response to the client.

Thanks for your help!

Forget it.

WSE 2.0 DIME is dead - long live WSE 3.0 MTOM!

Because I don't want to go through another such conversion anytime soon!!!
