Why WSE?

• For .NET Framework 1.x Web Services standards
  were still evolving.
• Pay as you go approach and WSE extensibility
  model mirrors SOAP and associated standards.
• .NET 1.x Web Services implementation tied
  un-necessarily to HTTP.

Securing Web Services

• WSE provides implementation of WS-Security,
  WS-Trust, WS-SecureConversation etc. specs.
• Authentication - security credentials (tokens)
  are placed in the message.
• Encryption
• Digitally signing messages

Web Service Policy

• WS-Policy allows separation of Service
  configuration from business rules.
• WSE 2 comes with a number of pre-defined policies
  out of the box.
• Facility for easily writing custom policy
  assertions.
• All the security settings we made previously in
  code can be done via policy.

SOAP Messaging

• Web Services in .NET 1.x were un-necessarily
  coupled to HTTP.
• WSE 2 Messaging provides other transports,
  framework for writing your own.
• Messaging patterns other than basic
  request/response.

Web Service Addressing

• WSE 2 drops WS-Routing in favor of the newer
  WS-Addressing.
• Useful for Addressing end-points by means other
  than HTTP.
• New EndPointReference class in System.Web.Services
  .Addressing replaces System.URI.
