User-Inferface-Technologies for Web-EnvironmentsMotivation

# Rich Internet Application (RIA) demands and features

> Rich user interface behaviours

> More responsive> Asynchronous communication

> Network efficient

> Enhanced client side Technology> Should be accessible from every kind of client

> Not limited to a Web browser environment

> Runs in a sandbox> Can run offline

User-Inferface-Technologies for Web-EnvironmentsMicrosoft Silverlight

# MS continued its commitment to user experience(UX)

# Silverlight 1.0 was introduced in 2007

> Cross-platform, cross-browser, cross-device> For designing, developing and delivering

> Media experiences

> Rich interactive applications# Silverlight 2.0 was introduced in 2008

> .NET Framework

> Deep Zoom technology> Digital Rights Management

# Moonlight for Linux via a cooperation with Novell

CoreCLR and BCL

# CoreCLR

> A subset of the CLR of the .NET Framework

> Full implementation of the CLI specifi

cation> Memory management, generics, exception handling

> CTS for programming language independency

> VES transforms managed codeto CIL code> JIT compiles CIL code to machine code

# BCL

> String-, event-, thread-handling; regular expressions;collections; cryptography; globalisation

> HTML/ JS bridge


6/22


User-Inferface-Technologies for Web-EnvironmentsWCF, LINQ, Sockets

05 / 13

# Windows Communication Foundation (WCF)

> Web feeds: RSS 2.0, Atom 1.0

> Web Services: SOAP Service 1.1, WCF Service,ASP.NET Web Service

> REST: low level HTTP API, ADO.NET Data Service API

# Components for data processing> Language Integration Query (LINQ)

> JSON and XML data serialisation

> POX processing# Bi-directional message transport via Sockets

# Control mechanism to enable cross-domain calls


7/22



06 / 13

DLR

# Dynamic Language Runtime (DLR)

> Language services for dynamic programming languages

> Dynamic type system> Dynamic method dispatch

> Dynamic code generation

> Hosting API> Supported languages: Managed JScript, IronPython,

IronRuby

> Advantage: easy developing with a simple text editor> Chiron: local Web server and build tool for .xapfiles


8/22



07 / 13

WPF, XAML, Controls

# Windows Presentation Foundation (WPF)

> Extensible controls, layout management, data-binding,

styles and template skinning> Opportunity of re-using skills, controls und code

> Currently no 3D and GPU support

# Extensible Application Markup Language (XAML)> Declarative, XML-based language for describing UI

controls and features

> Definition of entry points for code-behindtechnique> XamlReaderto create managed objectsfrom XAML

# ASP.NET server controls: e.g. Media Player Server Control


9/22



08 / 13

Formats, Deep Zoom

# Media formats

> Widely based on MS codecs

> Video formats: WMV7-9, WMVA with an implementationof VC-1 industrie standard for HD (WMVC1)

> Audio formats: WMA7-9, MP3

> Playlist formats: ASX (important for streaming)> Image formats: JPG, PNG; no GIF, SVG

# Deep Zoom

> Allows smooth in-place zooming and panning of largeimages by using fragmented, pre-rendered image parts

> Can be manipulated with standard Silverlight metaphors


10/22



09 / 13

Streaming and DRM

# Supported streaming protocols: MMS, RTSP, RTSPT

> Will be fall back to HTTP

# Silverlight Streaming Service> To host RIAs and media data for free

> 10 gb data storage with 5 gb traffic volume per month

# Helpful add-ons for Windows Server 2008> For bandwidth throttling, configuring and hosting

streaming media and playlists

# Digital Rights Management (DRM)> Built-in access control to protect music and videos

> Sends standard computer information to rights server


11/22



10 / 13

Additional Features

# CoreCLR security model

> Replaces the CAS model of the CLR and simplifies it

> Three layers of security> transparentcode, safe criticalcode, criticalcode

# Asynchronous programming and threading

> Allows programming task execution in the background> Background Workerand Dispatcherfor collaboration

> No synchronous communication via HTTP API

# Isolated Storagecomponent for accessing local storage# Naturally upload of large files impossible

>> Isolated Storagefor saving file upload information


12/22



11 / 13

Tools

# Separation of designing and programming

> MS Expression Studio for designers

> MS Visual Studio for developers> Similar project structure enforces cooperation

> Additional framework for browser-based unit testing

# XAMLPad as basic visual editor for XAML markup# Deep Zoom Composer for image composition and export

# Mono IDE with Moonlight SDK for non-Windows platforms

# Lunar Eclipse as visual XAML editor for Linux# Converter to transform SVG markup to XAML markup
