Question

Is it possible to use a custom WSDL with a .NET WebService? I would like to use a custom WSDL with my .NET WebService instead of the one generated by .NET as part of my WebService.

Answer 1

Actually there is a way to do this:
You can create your own WSDL (i.e. removing methods you don’t want to publish) and then make it available at a dedicated spot, this allows users to bind to it as normal.

To prevent users from just retrieving the default WSDL (foo.asmx?wsdl) you have to flip a switch in the web.config of your web service:

  <webServices>
    <protocols>
      <remove name="Documentation"/>
    </protocols>
  </webServices>

From the relevant MSDN section:

Note Removing the Documentation
protocol also disables WSDL file
generation for any XML Web services
within the Web application. This
prevents clients from generating a
proxy class unless a custom WSDL file
is created and provided for them.
