Binding information

Each operation needs to be linked to the server URL.

Right-click and select Generate Binding Content. This brings up the Binding Wizard.
All the defaults can be used so click Finish.

The effect of this can be seen in the source view of the editor (see the Design | Source tabs at the bottom of the editor window), which shows the generated XML.
