Prism & Silverlight: Part 1 - Taking Sketched Code Towards Unity

Posted By: Mike Taulty | Oct 27th @ 3:29 AM | 28,671 Views | 21 Comments
This is part 1 of a series of screencasts illustrating some of the ideas found in "Prism" or the "Composite Application Guidance" from the Patterns and Practices team that can be used to build Silverlight applications in a way that lends itself to testability and modularity.

In talking to customers building business applications with Silverlight I find that Prism (and it's friend Unity) is frequently mentioned but not everyone has seen it and so I thought I would explore it myself and capture some of the results of that exploration here.

We start off with some fairly basic code which we move towards making use of dependency injection and modularity;

and then we move that code into the Silverlight world and try to illustrate some specific areas of Prism;

and then finally we try and bring some of these concepts together in a longer, more realistic example of a simple Email application built using the Prism framework - warning, this is a much longer session but I wanted something that draws things together;

The recommendation would be that you watch the 10 screencasts in order but if that feels like too long a process or if you're already very familiar with concepts like dependency injection and containers like Unity then perhaps watch the last screencast first and then refer back to the previous screencasts if certain areas need more illumination.

I put the source code for Video 10 here for download as it's a bigger set of source and something you might want to explore after the video - this does not necessarily represent "best practise" but is, instead, just meant to illustrate some of the Prism ideas.

How can I download it and watch it on the train or plane?

 

Thx

The audio did not work in VLC for me, but did work in WMP 11 (fyi, I have the Expression 3 suite installed...)

Thanks for this Mike. It was the series that got me from reading about to using PRISM  & MVVM.

 

The journey from monolithic to composite app matches a battle we've had at Pentagon and this has helped us loads in pulling all the technical strands together.

 

A brilliant learning resource. Once again, thanks.
