There are two approaches to developing a web service, depending on whether you define the contract first or last. Correct Answer True
A web service contract is described using Web Services Description Language (WSDL). In contract-last, you expose an existing service interface as a web service whose service contract is generated automatically. In contract-first, you design the service contract in terms of XML and then write code to fulfill it.
