Now official: WSE 2.0 TP
UPDATE: Matt Powell has a new technical article on WSE
2.0 (MSDN): Programming with Web Services Enhancements 2.0
Keith is back and
has a very good reason for having been absent from blogging:
Web Services Enhancements (WSE) 2.0 Technology Preview
WSE 2.0 Technology Preview builds on the security, routing, and
attachments capabilities with new features including a policy framework,
enhanced security model, message-based programming model, and support for
multiple hosting environments.
WSE 2.0 simplifies coding by enabling
developers and administrators to apply security policies on Web services
running on the Microsoft .NET Framework. Web services communication can be
signed and encrypted using Kerberos tickets, X.509 certificates,
username/password credentials, and other custom binary and XML based security
tokens. WSE's enhanced security model provides a policy-driven foundation for
securing Web services across trust domains. A Trust issuing service can be
established for retrieving and validating security tokens. A secure
conversation can also be established by parties so that authentication and
authorization of calls within a session can happen more quickly than more
complex cryptographic operations.
The new message-oriented programming
model enables asynchronous communication for Web services implementations that
require support for long lived operations, batch processing, peer to peer
programs, or event driven application models. Web services that leverage WSE
can now be hosted in multiple environments including ASP.NET, standalone
executables, NT Services, etc. and can communicate over alternative transports
including HTTP or TCP.
WSE provides a foundation for building
applications based on Web services specifications published by Microsoft and
industry partners including WS-Security, WS-Policy, WS-SecurityPolicy, WS-Trust, WS-SecureConversationand WS-Addressing.
WSE 1.0 SP1 and the
technology preview can be installed side by side. Please review the product
readme for more information about WSE 2.0, including breaking changes from WSE
Congrats so far. This thing will definitely
be a milestone. Trust me.
And Microsoft is again top of the Web Services game
