In the last post I compared the new Nullable reference types that were introduced in C# 8 with using Option from language-ext, which tries to mimic the functional paradigm approach to representing the abscence of a value. One of the major drawbacks of Option in C# is that there is no built in language-support, instead […]

Nullable reference types compared to the Option monad
I wanted to investigate how Nullable reference types, the new big feature that was introduced in C# 8, compared to the Option type from language-ext. But let’s start with some information to set up the scene. Nullable reference types The way to indicate the abscence of a value in C#, as well as in many […]
Book review: Functional programming in C#
I have been interested in functional programming for quite some time, experimenting with both F# and Clojure as well as trying out some Scala. But I must admit that I have never really put full focus on it for any longer period, not until I found this book: Functional programming in C# – How to […]
.NET under the hood – The ’null’ keyword
I assume that you are familiar with the null keyword in C#. It represents a null reference, one that does not reference any object, and even though it has no type it can be assigned to any reference of any type. Null as a concept is quite abstract. It is often used to represent the […]
A functional approach to error handling in C#
Imagine that you want to write a simple console application that queries the user for two integers, divides the first integer with the second, and writes the result to the console window. What can go wrong in a simple program like this? The first thing that comes to mind is probably that the user might […]
The end of the .NET Framework?
I remember last autumn when I was out jogging. I was listening to an episode of a well known podcast on programming and the future of .NET was discussed. The hosts and the guest on the show were discussing the role of .NET Core and I remember that they recommended using Core for green field […]
When to NOT use interpolated strings
I am currently reading the newest edition of Jon Skeet’s book ”C# in depth” (https://csharpindepth.com/) which is a quite interesting read so far. There is however one thing in the book that made me feel really bad about myself. You see, I really think interpolated strings helps improve readability quite a lot, and therefore I […]

The Common Reuse Principle
What? The Common Reuse Principle (CRP) states: ”The classes in a component are reused together. If you reuse one of the classes in a component, you reuse them all.” In the last post I wrote about the Reuse/Release Equivalence Principle (REP). It says that reusable components must be releasable components, with everything that comes with […]
The Reuse/Release Equivalence Principle
What? When we group classes into components we strive towards making some of them reusable so that we can potentially use them for other purposes and also other teams in the organization may use them if they want to. The Reuse/Release Equivalence Principle (REP) states that ”The granule of reuse is the granule of release”. […]
