Seamless test authoring with ReSharper and AutoHotKey

Although I’m no big believer of code generation, the micro-code generation of ReSharper can be a huge timesaver. For every common snippet of code or common file I would create, I could create a simple template that might create a class, method,...

Polymorphism in Expression trees

While trying to be extra-clever today, I found a potential nasty issue when dealing with strongly-typed reflection . Suppose I have a simple hierarchy of objects: public abstract class Base { public abstract string Foo { get ; } } public class Child...

Spaces in identifier names in C#

While I’m a fan of descriptive member names for testcase classes and test methods, there wasn’t a great way to create readable text. Text in code editors is almost universally monospace, which reads very well for languages with lots of syntax. ...

Validation in a DDD world

It’s a common question, “Where do I put validation?” Simple answer: put it where it’s needed. But it’s not just a question of “where”, but of “when”, “what” and “why”. If we treat our entities as data holders, we might think to put all of...

Language feature parity and the polyglot programmer

For the average .NET developer, language features in the other .NET language don’t matter 99% of the time. Unless of course, you’re using a framework designed for features that don’t exist for the language you’re using. Such is the plight for a...

DDD Aggregate Component pattern in action

In my last post, I went on a long-winded rant on how the composition and the Aggregate Component pattern can ease the burden of the interaction between Entities and Services. The question comes up often on DDD or IoC forums: How do I inject/use...

Crafting wicked domain models with Components in DDD

Domain-Driven Design can help focus development efforts into crafting a strong, expressive domain model. In Evans’ book, he dives in to a series of patterns which, when combined, form that strong domain model. These patterns include Entity...
