How to: Connect to Data in a Service

You connect your application to the data returned from a service by running the Data Source Configuration Wizard and selecting Service on the Choose a Data Source Type page.

Upon completion of the wizard, a service reference is added to your project and is immediately available in the Data Sources Window.


The items that appear in the Data Sources window are dependent on the information that the service returns. Some services might not provide enough information for the Data Source Configuration Wizard to create bindable objects. For example, if the service returns an untyped dataset, then no items appear in the Data Sources Window upon completing the wizard. This is because untyped datasets do not provide schema, so the wizard does not have enough information to create the data source.


Your computer might show different names or locations for some of the Visual Studio user interface elements in the following instructions. The Visual Studio edition that you have and the settings that you use determine these elements. For more information, see Visual Studio Settings.
