Maps.google.comJavaScript rules!

Big time!Different Browser DebuggingNo compilingSyntaxNo intellisenseNo static typing (duck typing!!)No animationsJavaScript sucks!

Written in JavaScriptIt is a lightweight JavaScript library (compressed based lib, 19 kb)Helps developer / designer to keep things simple and reusableVisual Studio supports JQueryPart of every web app / siteIntellisense support A great library for developing AJAX-based applicationWhat is JQuery?

1- Cross-browser (IE 6.0+, Firefox 2+, Safari 3.0+, Opera 9.0+, Chrome)2- Powerful and easy to useSame selectors as in CSSDesigner can learn it fastMore readable JavaScript code3 – AnimationTons of useful plug-ins and functionalitiesWhy JQuery?3 good reasons

JavaScriptwindow.onload = function() { alert("welcome"); }JQuery$(document).ready(function() { alert("Thanks for visiting!"); });1- Cross-browser

JavaScript“onload” is only loaded when all images are loaded in the pageJQuery“$(document).ready” is loaded as soon as the Document Object Model is readySimilar to init() method in aspx page1- Cross-browser – Explanation

Selector$(document).ready(function() { $("a").click(function() { alert("Hello world!"); }); });It will add any click-event to “a” tag2 – Powerful

What is ASP.NET MVC ...and is WebForms dead?

Our ancestors developed for the web in ASP script...

We have had WebForms...Compile

ASP.NET MVC Model - View - Controller

WebForms == WinForm developers MVC == HTTP + jQuery + CSS developersDoes ASP.NET MVC replace WebForms?ProductivityControl

Not just cool... Not just for testability...Not just because you get more control...Because you get more perspective!Why ASP.NET MVC?

Web is an HTTP highwayCool TechControlsHTTP / HTML

Microsoft Silverlight is a cross-browser, cross-platform implementation of .NET for building and delivering the next generation of media experiences & rich interactive applications for the Web.

<UserControl x:Class="SilverlightApplicationHalloWelt.Page"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Width="400" Height="300"><StackPanel><Button Width="400" Height="20" Content="Click me" Click="Button_Click"></Button><TextBlock x:Name="textblockOutput" Width="400" Height="20" Text="empty"></TextBlock></StackPanel></UserControl>"Hallo Welt" - XAML

"Hallo Welt" – XAML in Design mode

private void Button_Click(object sender, RoutedEventArgs e){textblockOutput.Text = "Hallo Welt";}"Hallo Welt"

Silverlight – Under the hood

Silverlight LimitationsNo full access to Windows API & .NET APISilverlight is a subset of .NET frameworkWPF features not in Silverlight:http://msdn.microsoft.com/en-us/library/cc903925(VS.95).aspxHardware acceleration

TriggersSilverlight LimitationsHosting Silverlightin Windows Forms applicationIn OfficeNo sandbox customization No external API calls (e.g. P/Invoke, COM, full .NET) No Office integration

Silverlight LimitationsNo Secure SaveAs dialog SL3 has a secure SaveAs dialog

Silverlight LimitationsOffline supportSL4 has Offline and Out of Browser support although more limited than WPF No Sync Framework No local DBCan manually serialize data on the Isolated Storage

Silverlight LimitationsNo Context menu No Right Click Event No context menu triggered by Right Click. Hacks exists but are not recommended due to the need to put the SL plug-in in windowless mode, introducing performance issueNo “Right click – Open in new tab”

Silverlight LimitationsNo printing support Server side PDF or Open XML generation Client side manual HTML generation. Need to implement the formatting logic twice one for XAML and one for HTML Final version of SL 3 should provide more “hacks” for generating bitmaps from visuals enabling some more options for client side printing compared to the manual HTML generation. Still done through HTML bridge. This will for example enable printing of Charts.
