Clients rely on contracts defined by the Web Services Description Language (WSDL) to communicate with services. The WSDL contract describes the operations available at each service endpoint and the format and schema for messages related to each operation, including the schema for complex types exchanged between parties. Making changes to contracts once they have been published is a delicate matter, as that can create compatibility issues with existing clients. The only option is to ensure backward compatibility or expose a new version of the contract for new clients. In this webcast, we focus on approaches to version tolerance and contract versioning. We provide guidelines for strict and non-strict approaches to contract versioning, describe how to design service contracts and data contracts to be version tolerant, and illustrate how to handle explicit versioning of service contracts and data contracts with the least impact to business components that support your services.
