Well, something is wrong somewhere. I just did it again and now I know why it ended up like that. Basically, when adding a Web Service reference in the project, now, we have being prompted with this:

Compatibility

Add a Web Reference instead of a Service Reference. This will generate code base on .NET Framework 2.0 Web Services technology.

So, at first, I thought I would do right by using the new standard. But, if I do it, I lose the capability to call my methods with the parameters. As, with this new approach, we are forced to use the SOAP enveloppe. So, I do not know why this is known as Compatibility as we cannot do what we used to do.

Did you succeed to add a Web Service reference in a project, under this new Service Reference, and be able to call a Web Service method such as DoThis("MyUserame", "MyPassword")?
