To build these applications and services, developers can use their existing Microsoft® Visual Studio® 2008 expertise. In addition, Windows Azure supports popular standards and protocols including SOAP, REST, and XML. Windows Azure is an open platform that will support both Microsoft and non-Microsoft languages and environments.
