I already have an existing WSDL file and want to generate C# proxy code
and C# test client using Visual Studio .NET 2003 with Framework Version
1.1.

I firsted created ASP.NET web service, and added web reference that
points to the WSDL URL. I am able to see the methods for that web
service, and I am able to see C# proxy code generated by WSDL. Then I
press F5 to compile and run the web services.

However I got the following error message, and I couldn't see any
methods on the test client page. If I created my own web service and
press F5, it allows me to choose which method to test on the test
client page.

This web service is using http://tempuri.org/ as its default
namespace.
  Recommendation: Change the default namespace before the XML Web
service is made public.

any ideas? this should be very simple but I have no idea why it doesn't
work.
