Agenda Organizing an event like TechDays... Problem... Solution & technologies Silverlight, WCF RIA Services, Windows Phone 7 ASP.NET MVC jQuery & jQuery Mobile Windows Azure What to remember?

Organizing an event like TechDays... Feedback loop with conference attendees is difficult How are the sessions? How’s each speaker? Is the airconditioning too low? Twitter is an option Not everyone uses #techdays11 Earliest feedback usually after the event

Live feedback? Let’s build a solution... Establish a connection with speakers & audience Short, to-the-point questions: How’s the speaker? How’s the session? Any remarks? Top session list Accessible through a variety of devices

High level overview Large screens Front-end for attendees Back-end

3 screens and a cloud? Well... Windows Phone 7 Any device with a web browser can navigate to iPhone iPad Android Symbian... Web browser...and a cloud!

Backend: WCF RIA Services Automates/simplifies creating a service boundary trust Common concerns Validation Authentication / authorization Change tracking

Backend: WCF RIA Services Best way to work when main app is a Silverlight app DomainContext / Entity generation Authentication / Authorization Validation Change tracking Operations can be exposed as SOAP / OData endpoint Reuse of service layer throughout a variety of clients Every Domain Service IS a WCF Service Reuse authentication service

Backend integration: Silverlight applications Back Office Administrative SL app WCF RIA Services way of working Also used for reporting / charting

DEMO Back office / WCF RIA Services

Backend integration: Silverlight applications Top session list Focus on design Twitter app Focus on design Twitter API

Backend integration: Windows Phone 7 application Focus on design UI, UX & product design is important … and can cost quite some time Integration with WCF RIA Services Through SOAP endpoint … and even the authentication service works Concerns about data usage Connections are only made when absolutely necessary

DEMO Windows Phone 7

ASP.NET MVC 3 One set of Controllers Three sets of Views Web browser Mobile browser (jQuery mobile) WP7 web browser (pointing to Marketplace) 17

ASP.NET MVC 3 & WCF RIA Services Uses WCF RIA services through SOAP endpoint So what about OData? There’s some tuning required: Optional parameters are cumbersome Authentication service By the way... jQuery & WCF RIA Services:

DEMO ASP.NET MVC 3

jQuery mobile Alpha stage! Cross-platform, cross-device Based on HTML5 markup & jQuery Touch optimized layout & widgets Theming Automatically provides: Transitions Navigation framework

DEMO jQuery Mobile

ASP.NET MVC 3 Application built using standard ASP.NET MVC 3 project template And the new kids on the block!

New kids on the block? Package management Simplifies 3rd party components integration Has a rich ecosystem of packages I focus on development, NuGet does package mgmt. Takes application wiring out of hands Uses MEF but adds: MVC3 integration CompositionDependencyResolver Integrates assemblies in /bin Exports everything : IController by convention Available through NuGet as well

DEMO NuGet - MefContrib

Windows Azure & SQL Azure Rapid availability of infrastructure Only one instance during development More instances right now Tools you're familiar with Seamless integration with WCF RIA Services, ASP.NET MVC 3,... Pretty cheap on the bill! 25

DEMO Windows Azure & SQL Azure

What to remember? Design takes time WCF RIA Services Made rapid application development possible Integrates fine with other technologies Waiting (anxiously) on OData write support jQuery Mobile is a pleasant surprise ASP.NET MVC 3 is very extensible Windows Azure allows for cheap, temporary hosting 27
