I'm trying to get a basic web service up and running with WSE 2.0, but
it always fails with the exception:

--------- Exception below -----------
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.
---------- End of exception ----------

Here's what I've been trying: I downloaded and installed the WSE 2.0
files. I fired up VS.NET and created a simple web service and
uncommented the HelloWorld method. I setup the WS to use WSE 2.0 by
right clicking on the project, selected WSE Settings 2.0 and enabling
both the checkboxes on the General tab. I hit F5. So far, so good. But
when I invoke the method from IE, all I get is an HTTP 500 Internal
Server Error page.

OK, so I figure this might be because WSE2.0 and 1.0 are incompatible.
(I dunno, I'm just shooting in the dark here).

Anyway, so then I made a WinForms application and enabled WSE2.0
support. Then I added a reference to my service and inserted the
following code:

--------------- Exception  text below ---------------

localhost.Service1Wse svc = new
WindowsApplication1.localhost.Service1Wse();
svc.HelloWorld();

When I try to run this code, I get the following exception. This is the
full exception text below:

I can't understand why it says my proxy isn't right. It was
autogenerated by VS.NET 2003. Do I need to do something else to get it
to work with WSE2.0?
