  • Book review: C# in depth (4th ed)

    C# in depth is written by Jon Skeet, a software engineer currently working at Google. He is known for being an extremely active user on Stackoverflow, having an odd fascination in the field of date and time (he is one of the Noda Time library authors), and being very interested in the C# language. As […]

  • 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 […]

  • Book Review: Agile Principles, Patterns, and Practices in C#

    I have been reading Robert C. Martin’s and Micah Martin’s book, Agile Principles, Patterns, and Practices in C#, for quite a while now. The reason it has taken me so long to finish is that it is packed with so much information and covers so many aspects of software development, enough for at least 3-4 […]

  • The Stable-Abstractions Principle

    What? This is the last of the Principles of Package and Component Design, the Stable-Abstractions Principle (SAP). It says: ”A component should be as abstract as it is stable.” In the Stable-Dependencies Principle (SDP) post we learned that stability, or in that case Instability, I, can be calculated using the formula I = Ce / […]

  • The Stable-Dependencies Principle

    What? The Stable-Dependencies Principle (SDP) says: ”Depend in the direction of stability.” What this means is that the direction of the dependencies in the component dependency graph should point towards more stable components. To understand what this means we need to define stability for a component. Uncle Bob turns this around and defines a way […]

  • The Acyclic Dependencies Principle

    What? The Acyclic Dependencies Principle (ADP) is the first of three principles that deals with the relationships between components. It says: ”Allow no cycles in the component dependency graph.” If you draw the components and the dependencies between them and you are able to follow a dependency back to a component you have already visited, […]

  • The Common Closure Principle

    What? The Common Closure Principle (CCP) states: ”The classes in a component should be closed together against the same kind of changes. A change that affects a component affects all the classes in that component and no other components.” To put it in other words, a component should not have multiple reasons to change. This […]

  • 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 […]
