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 screensFront-end for attendees Back-end

3 screens and a cloud?

• Well...• Windows Phone 7• Any device with a web browser can navigate to

http://techdays.realdolmen.com• 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

DEMOBack 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

DEMOWindows 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: http://jeffh.me/wcfriajs

DEMOASP.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

DEMOjQuery 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

DEMONuGet - 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

DEMOWindows 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
