Silverlight 2 Lays the Foundation Huge step forward from SL 1 Rectangles -> Buttons JavaScript -> C#/VB Enables business applications today Has the needed platform building blocks Core – CLR, BCL, XML, Networking UI – Core controls, control model, layout, styling, databinding Lays the foundation for what comes next

Huge step forward from SL 1

Rectangles -> Buttons

JavaScript -> C#/VB

Enables business applications today

Has the needed platform building blocks

Core – CLR, BCL, XML, Networking

UI – Core controls, control model, layout, styling, databinding

What platform for your business app? Richness Reach

What makes a business app tick? Business apps are almost universally about working with data in some shape or form. At it’s a heart, a business app needs: A way to move data between tiers A way to shape data (sort, filter, etc..) A way to bind & display data A way to soundly apply business logic

Business apps are almost universally about working with data in some shape or form.

At it’s a heart, a business app needs:

A way to move data between tiers

A way to shape data (sort, filter, etc..)

A way to bind & display data

A way to soundly apply business logic

Moving Data – Simple Cases Browser integrated networking stack Cookie Support Make direct HTTP requests (e.g. RSS Feeds) Complete Service stack Use WCF to build SOAP or REST services Simple “Add Service Reference” experience to consume Use WebClient to consume REST and Plain-Old-XML

Browser integrated networking stack

Cookie Support

Make direct HTTP requests (e.g. RSS Feeds)

Complete Service stack

Use WCF to build SOAP or REST services

Simple “Add Service Reference” experience to consume

Use WebClient to consume REST and Plain-Old-XML

Moving Data – Advanced Cases Cross-domain Support Requests constrained to same domain by default Cross domain enabled via server side policy file 2-Way communication Sockets – Low level transport WCF Duplex – HTTP pull based messaging ADO.NET Data Services Easy way to expose & consume data via REST Optimal for straight data access layer -> client scenarios

Cross-domain Support

Requests constrained to same domain by default

Cross domain enabled via server side policy file

2-Way communication

Sockets – Low level transport

WCF Duplex – HTTP pull based messaging

ADO.NET Data Services

Easy way to expose & consume data via REST

Optimal for straight data access layer -> client scenarios

Data Binding Data Binding One way – any CLR object w/ INotifyPropertyChanged Two way Value Converters for converting/formatting Core Validation Hooks Collection Binding A full & growing set of controls Data Template based customization Leverage of ObservableCollections (esp. Blend)
