Microsoft has released a preview of an upcoming update to its Web Services Enhancements (WSE) kit, focusing on security.
Due for general release by the end of this year, the free kit for Visual Studio .net users is intended to enable development of what Microsoft describes as advanced web services.
WSE 2.0 features security improvements and enables developers to build seb services that are compliant with a set of specifications released by Microsoft and IBM, including WS-SecurityPolicy and WS-Addressing.
These specifications, which have not yet been submitted to an industry standards organisation, would receive a volume boost by developers who use Microsoft's kit.
"[WSE 2.0] is fully integrated with Visual Studio and provides additional libraries in the .net Framework for doing security policy and Soap messaging," said Rebecca Dias, Microsoft product manager for advanced web services.
Microsoft is releasing an early version of the kit to give users and vendors time to review it and provide feedback. The new version builds on the security, routing, and attachment capabilities of Version 1.0 of WSE.
Version 2.0, available at https://www.microsoft.com/net, provides a message-based object model that supports multiple transports, including HTTP and TCP, and asynchronous and synchronous communications.
In synchronous communications, messages are sent and the sender must wait for a reply, unlike asynchronous communications, in which a request can be sent and retrieved without waiting for a reply.
Asynchronous communications is useful for long-running transactions such as with routing of payroll requests or purchase orders, Microsoft said.
