vision and goals
Vision and Goals
  • Simplify RIA-style application development
    • n-tier is hard, and un-natural

  • Bring ASP.NET-style productivity to RIA development
    • Building blocks for data, security, etc.
    • Focus on scenarios
value propositions
Value Propositions
  • Focus on data in an end-to-end manner
  • A unified story for client and server development
  • A prescriptive framework that targets key scenarios, and leads the common developer to a pit of success
a unified story for client and server
A Unified Story for Client and Server
  • Client is an extension of the server

summary
Summary
  • RIA Services focuses on writing n-tier apps by treating them as one logical application
    • Still get n-tier goodness from the architecture/pattern without the plumbing getting in your way
  • RIA Services provides a pattern for encapsulating application logic on the middle tier that can be useful in a variety of scenarios
    • DAL-agnostic
    • Multiple presentation layers
