Sun, 07 Sep 2008 03:27:19 GMT

Udi wrote about this topic, but I never really liked the solution. To me it seemed complex and over architected, even the solutions from the commenter's where surprisingly complex (No disrespect for Udi or any of the commenter's intended). My solution looks like this.

Onion Architecture in Praxis

Thu, 14 Aug 2008 03:23:26 GMT

Jeffrey Palermo has coined the pattern onion architecture, so what is it? Actually it is "just" my default architecture, and has been for some time now.

Visual Studio Theme Generator

Thu, 07 Aug 2008 19:16:02 GMT

A fun little ASP.NET MVC Application I wrote to generate Visual Studio themes based off of 3 given colors. I have always felt that selecting every color to make a decent theme is way too repetitive. This web application automatically chooses complements / contrasts based off your initial color selections (and uses jQuery to let you preview your theme before creating). Check it out and let me know what you think.

Learning by Sample: Monorail and AspView

Sat, 19 Jul 2008 01:23:49 GMT

I really like the AspView View engine for Monorail, not that the other view engines are bad - but... Intellisense and a familiar syntax just does it for me, however the documentation is lacking behind. So I have converted the monorail getting started sample application to use aspview.

Tue, 08 Jul 2008 12:42:17 GMT

I really like the look of my tests specifications, they read almost like plain English. After fumbling around for a while, I finally get how to specify an expected exception.

Doing BDD

Tue, 08 Jul 2008 03:06:40 GMT

Basically it a shift towards specifying behavior instead of testing behavior. The specification consists of 3 parts: 1: A namespace with called "Specs_for_subject" 2: One or more classes called "When_operation_on_state", with a SetUp/Init method that performs the "operation_on_state" 3: One or more methods called "Should_expectation"
