What's New for JScript in IE8?

Janakiram MSV — Tue, 09 Sep 2008 02:12:00 GMT

The web developer community is curious to know what’s new for JScript in IE8. In this show, the JScript Evangelist, Janakiram MSV interviews the program managers who own the key JScript features.

The JScript team is based out of IDC in Hyderabad. We own the scripting engine for IE8 & Silverlight and provide authoring and tooling experience through Visual Studio and IE8. We also engage with the ECMA standards body to drive the JScript standardization process.

This is show is to breifly share the work that we do here. You will hear us talk about the new and improved JScript engine and the Developer Tools that are part of IE8.

You can find our team blog at http://blogs.msdn.com/jscript! Feel free to drop a comment with your feedback!

Happy Scripting!

geekSpeak recording: Advanced ASP.NET with Michele Leroux Bustamante

llangit — Thu, 27 Mar 2008 22:43:16 GMT

Michèle Leroux Bustamante is chief architect of IDesign Inc., Microsoft Regional Director for San Diego, and Microsoft Most Valuable Professional (MVP) for Connected Systems. At IDesign, Michèle provides training, mentoring, and high-end architecture consulting services focusing on Web services, scalable and secure architecture design for Microsoft .NET, federated security scenarios, Web services, and interoperability and globalization architecture. Michele participates in software design reviews for products in the Microsoft road map, including Windows Communication Foundation, CardSpace, and other security-focused products. She is a member of the International .NET Speakers Association (INETA), a frequent conference presenter, conference chair for SD West, and is frequently published in several major technology journals. Michele is also on the board of directors for IASA (International Association of Software Architects), and a program advisor to University of California San Diego (UCSD) Extension. Her latest book is Learning WCF (O'Reilly, 2007)—see her book blog here: www.thatindigogirl.com. Reach her at www.idesign.net and her main blog at www.dasblonde.net.

In the geekSpeak, Michele discusses timely topics in ASP.NET such as extending the ASP.NET profile service by appropriately using custom HttpModules to support dynamic implementation of master pages, application localization and more. She goes on to discuss improvements to ASP.NET like the AJAX-programming paradigm with asynchronous access to data, and then the ASP.NET 3.5 extensions - new MVC, new ADO.NET data services libraries.

Michele gives her perspective on RIAs, including Flash, Silverlight, typical web applications and WPF (or rich client) - when to use which one from an architectural perspective.

She goes on to discuss SOAP vs. REST WCF services and the evolution of the programming model from raw SOAP message construction to REST-based calls which include wrappers and then onto JSON-based WCF services. Next she shows the the ServiceHostFactory, and the WebScriptServiceHostFactory. She then presents the ASP.NET extensions ADO.NET data services (formerly Astoria). She concludes with an interesting discussion of when to use which type of service - SOAP or REST.

Adding Closed Captioning to video using Silverlight, ASP.NET AJAX, WCF and an external data source

keydet — Thu, 01 Nov 2007 19:30:00 GMT

In my previous Silverlight Closed Captioning screencast here, I showed you how to use Expression Encoder to import Closed Captioning information to produce a solution without writing a line of code. What if you store your Closed Captioning information in an external data source (database, SAMI file, XML file, etc.) and want to keep it there? Do you have to reprocess all of your videos using Expression Encoder? Of course not, but you do have to write some code:). In this screencast, I show you how to use Silverlight, ASP.NET AJAX, and the Windows Communication Foundation (WCF) to solve this problem.

You can download the sample code via my blog at http://devkeydet.spaces.live.com/blog/cns!1F72DA7294089597!452.entry.

Mobile Model in MVP web app

Andrew Davey — Wed, 17 Oct 2007 18:33:33 GMT

This screencast continues from the work I demonstrated in a previous screencast: Script# to make writing a client-side web app much more seemless than the usual javascript/XML/JSON/web service madness.

I'm developing the ideas shown here in a project at the moment. If there is sufficient interest I may extract a framework to give to the community.

How do people feel about this approach to web development? What kinds of additions/modifications should be made?

p.s. I have a bit of a cold at the moment, so sorry for the croaky voice in the recording!

Programming JSON with WCF in .NET Framework 3.5

Charles — Tue, 21 Aug 2007 00:28:20 GMT

Technical Evangelist Matt Winkler meets up with Eugene Osovetsky and Ghenadie Plingau, a PM and developer, from the WCF team to talk about returning JSON from a WCF service. JSON (JavaScript Object Notation) is s text based serialization of a JavaScript object, allowing one to new up a variable right from the string of JSON. Eugene hows how a developer can use the WCF programming model to serve JSON to AJAX clients. We also talk about how this is implemented in WCF as well as cool applications of this, namely to call WCF services from AJAX. He then shows off a cool tank game sample that allows two individuals to compete via a JavaScript game that is communicating with WCF.
