Evolving code over time

Given economics, time constraints, resource limitations, etc.; you can't write all the functionality for a given solution for a single release. Even if you weren't limited by these constraints, you're likely to get changing requirements as...

A Upcoming Pandemic of Domain Anaemia

There's a well-known anti-pattern called the anaemic domain model[1][2]. This anti-pattern basically says domain entities, chronically, have little or no behaviour (remember, object-oriented design is about attributes and behaviour). It should be...

House of Cards Design Anti-pattern

I've had this anti-pattern in my head for years.  It's an observance of some projects and methodologies that I've witnessed over the years.  I believe it's a form of Voodoo Programming , Programming by coincidence , and is often...

Becoming a Visual Studio Jedi Part 1

Becoming a Visual Studio 2008 (and often Visual Studio 2005) Jedi In much the same grain as James' Resharper Jedi posts, I'm beginning a series of posts on becoming a Visual Studio Jedi. It involves getting the most out of Visual Studio off-the...

Location of unit tests.

I had a short conversation at Alt.Net Canada about the location of unit tests. I personally tend towards a distinct unit test project. But, I deal with mostly commercial, off-the-shelf (COTS) projects where I simply can't ship code like that. I also...

The winds of change are blowing

The essence of ALT.NET, or at least the essence that people made use of, was that it was a venue for improving one's skills.  There has always been an undercurrent of other agendas there; but they never really took root. The problem with the...

Law of Reversibility of Attributes

I've come up with a simple law called Law of Reversability of Attributes. It’s based on the physics law of a similar name. Basically what the law means is that the inverse of a transformation should result in a return to the original state....

DataGridViewColumn.Frozen

DataGridViewColumn.Frozen is documented as "When a column is frozen, all the columns to its left (or to its right in right-to-left languages) are frozen as well." Which is nice until you think of the consequences. The consequences being that...

ITSWITCH #1: Answer

Last post I detailed some code that may or may not have something wrong in it.  If you thought InitializeOne and IntializeTwo are semantically identical (e.g. they differ only by performance), you'd be wrong. If you simply ran the code, you'd...

Nested Types

Recently Michael Features blogged about nested types . The title was almost "nested types considered harmful". I don't agree. I don't agree that they're any more harmful than any other C# construct (except goto...). Nested types...

Entity Framework Petition of Vote of Non Confidence

I had intended to be happy simply being a signatory of ADO .NET Entity Framework Vote of No Confidence. But, there's people suggesting signatories of this petition are wackos or on the fringe. Do yourself a favour and read the petition . Read what...

Fundamentals of OOD Part 3: Method Cohesion

Single Responsibility Principle (SRP) helps us write more cohesive types and methods. Cohesion is the relatedness of the members of a type to each other and the relatedness parts of a method's code to other parts. Method cohesion Often times a method...

Spaces or Tabs?

In this day and age it seems silly to get into a discussion about whether your companies coding guidelines should have a section mandating either spaces or tabs for indents. Tabs are clearly more flexible, but I really don't think it matters at all;...

Fundamentals of OOD, Part 2 - Encapsulation Scope

Let's look at the ubiquitous Person concept. It might seem logical that an application that deals with people should have a Person interface for classes to implement. For example: public interface IPerson { String GivenName { get; set; } String SurName...

Fundamentals of Object-Oriented Design (OOD) Part 1

With increased usage of patterns and situationally specific strategies, people sometimes lose sight of the concepts and principles behind these patterns and strategies and fail to follow them when they're not using patterns or strategies. I feel it's...

Upcoming C# 3 Guidance From Microsoft

Mircea Trofin has some design guidelines with regard to some C# 3 language additions (that I assume will make it into a revised Framework Design Guidelines of some sort). They more less agree with the guidelines I published in Code Magazine a while ago...

Single-Entry, Single-Exit, Should It Still Be Applicable In Object-oriented Languages?

Before the modern high-level languages Edsger Dijkstra came up with "Structured Programming". This programming methodology relied on the programmer to form and enforce most of the structure of the program--manually keeping sub-structures and...

A Time and Place for Code Comments

I've dealt with more than one person who believes all code comments are bad. The first person I encountered who said that also asked me to explain why a particular algorithm was used instead of another because there were no comments explaining it...
