Question

Every new web service you create using visual studio comes with a predefined namespace like this:

[WebService(Namespace = "http://tempuri.org/")]

My web service will run at different clients, and on different domains, so because of this I don’t know the domain upfront during development, also I don’t want to have to edit this file, each time I deploy to a new client.

What exactly should the value of Namespace be? It seems like a web address, but that doesn’t make sense to me.

Answer 1

It’s kind of ironic but the best answer is under : http://tempuri.org/

quote

Each XML Web Service needs a unique namespace in order for client applications to distinguish it from other services on the Web. By default, ASP.Net Web Services use http://tempuri.org/ for this purpose. While this suitable for XML Web Services under development, published services should use a unique, permanent namespace.

Your XML Web Service should be
identified by a namespace that you
control. For example, you can use
your company’s Internet domain name as
part of the namespace. Although many
namespaces look like URLs, they need
not point to actual resources on the
Web.

For XML Web Services creating using
ASP.NET, the default namespace can be
changed using the WebService
attribute’s Namespace property. The
WebService attribute is applied to the
class that contains the XML Web
Service methods. Below is a code
example that sets the namespace to
“http://microsoft.com/webservices/“:

C#
[WebService(Namespace="http://microsoft.com/webservices/")]
public class MyWebService {
    // implementation
}
