Building applications with WCF RIA Services

by nixusg 24. March 2010 21:26

RIAServices1 Building Rich Internet Applications (RIA) can be difficult. Validation, asynchronous calls and authentication are just some of the considerations you need to make when developing client-server applications. This is where the WCF RIA Services come to the rescue by simplifying these tasks!

This is the session presented at DevDays 2010 and walks you through creating a line-of-business application from end-to-end using Visual Studio 2010, Silverlight and ASP.Net along with the WCF RIA Services platform. We demonstrate how validation can flow from the server to the client, how asynchronous operations can be abstracted away, how to easily implement authentication and much more.

So how do you get started with WCF RIA Services? Well firstly you will need some of the tools:
1.    Visual Studio 2010
2.    WCF RIA Services RC
3.    WCF RIA Services Toolkit

Now you are all setup and ready to go! The video from DevDays should be released soon but if you want to get started now go ahead and check out some of the getting started videos at the Silverlight site

The slides and demo code from the talk are also available here:

A lap around AppFabric

by nixusg 24. March 2010 21:18

AppFabric1 Are Scalability, Availability and Ease of Management important to you? Well then AppFabric is the new technology for you!

This is the session presented at DevDays 2010 shows you how Windows Server AppFabric (“Dublin”) can make your WF (Windows Workflow Foundation 4.0) and WCF (Windows Communications Foundation 4.0) applications' “life after F5” (deployment, maintenance) simpler and easier to manage with advanced message logging, routing, simplified hosting and more.

The session also demonstrates how AppFabric Caching (“Velocity”) allows you to build applications with superior performance and stability with features ranging from reliable distributed data & sessions to simple data sharing.
So want to get started with AppFabric? Well just go ahead and download all the bits you need from the AppFabric site

The sides and demos from the presentation are also available here:

Please feel free to contact me with any questions you may have.

Single Responsibility Principle

by nixusg 24. June 2009 23:06

For those who attended the SA Developer.Net talk tonight or anyone else who may be interested the slides and video for the Single Responsibility Principle section of this talk can be found at the bottom of this post.

The Single Responsibility principle deals with application architecture and states "There should never be more than one reason for a class to change"

Some benefits of applying the Single Responsibility Principle include:

  • Code complexity is reduced by being more explicit and straightforward
  • Readability is greatly improved
  • Coupling is generally reduced
  • Your code has a better chance of cleanly evolving

For details on the other topics of this session the OCP (Open-Closed Principle) and LSP (Liskov Substitution Principle) please contact Johan or Daniel. Their blogs are http://dotnet.org.za/johanvw/ and http://dotnet.org.za/danielvanwyk/ respectively.

I hope you all enjoyed the presentation or video.

For all those who attended my sessions "The Buzzword Puzzle: Web technology integration" at Microsoft DevDays 2009 or anyone else who is interested the resources and screencast are available for download below.

The blurb for the presentation goes as follows: "We often see various web technologies shown off in isolation as they come out but never really see them operating together to form a complete solution. This presentation will introduce the ease with which various Microsoft technologies integrate including Silverlight 2, AJAX, WCF, jQuery and more!"

Please send me any questions you may have about the talk. Hope that you enjoyed it!

Entity Framework: A scenic tour

by nixusg 8. March 2009 23:57

For all those who attended my sessions "Entity Framework: A scenic tour" at Microsoft DevDays 2009 or anyone else who is interested the resources and screencast are available for download below.

The blurb for the presentation goes as follows: "Join us on an introductory tour of the ADO.Net entity framework, an advanced data access technology that bridges the gap between the database schema and objects in your application. We will explore the new mapping capabilities that allow one to map unwieldy database tables to neat objects that make use of object oriented principles such as inheritance. Queries will be demonstrated against this new Entity Model using both Entity SQL and Linq to Entities. We will end off the tour by briefly touching on some of the more advanced features of the framework."

Please send me any questions you may have about the talk. Hope that you enjoyed it!
