Patterns-Based Silverlight Development – Part IV – Service Layer

In this post, I will be building the WCF Services layer that my client layer will call.  I will be using the custom binding made available with Silverlight 3 that enables a decreased message size through encoding the message as binary rather than text.  I will also write some code to test this layer.

The Bagbys Are Moving to London

As some of you know, my wife Carrie works for American Express in Arizona.  Recently she was offered a great career opportunity in London and we have decided to pursue it.  It was a very difficult decision for us on many levels.  First and foremost, we are leaving behind our friends and family who mean the world to us.  Secondly, I have to leave my job with Microsoft and DPE (Developer and Platform Evangelism).  For over 3 years, I have had the privilege to work for the finest organization in the world with the best team I could imagine.  I am not embellishing when I tell you that for 3 years I have loved going to work.  This job will be hard to equal.

Patterns-Based Silverlight Development Blog / Screencast Series Index

I am in the midst of putting together a blog / screencast series illustrating developing Silverlight 3 application, taking advantage of various design patterns.  Some of the patterns we will cover are the Repository, the Pipeline, the Service Agent and Model View ViewModel.  I will be building a Sample HelpDesk Application along the way (see below).

Patterns-Based Silverlight Development – Part III – Pipeline Pattern

In yesterday’s post, I build our Repository interface and the implementation, as well as added some server-side validation, following a simple pattern.  I also added a test project and wrote some tests to test the our validation logic.  In this post I will implement the Pipeline pattern.  I will then implement a fake repository and use it to test our Pipeline.

Introducing Parallelism into your programs

Overview

A little over a month ago, I volunteered to develop a session for the Windows 7 / Windows Server R2 launches that are being delivered across the country and beyond  The session I worked on I affectionately call “An Introduction to Parallel Programming”.  In that session I wanted to illustrate various approaches you can take when introducing parallelism to your applications: 1) Fine-grained parallelism, 2) Structured parallelism  and 3) PLINQ.

The approach I chose was to start with an a sequential application and parallelize it using each of the 3 approaches.  The application I wrote simply creates a thumbnail image for every image in a specific directory.  This post provides a link to a screencast I did on this subject, provides a brief overview of each approach and illustrates how my sample program looks with each approach.
