From Dependency Injection Principles, Practices, and Patterns by Steven van Deursen and Mark Seemann
What purpose does DI serve? DI isn’t a goal in and of itself, rather a means to an end. Ultimately, the purpose of most programming techniques is to deliver working software as efficiently as possible. One aspect of that is to write maintainable code. This article discusses what DI is (and is not).
From Learn PowerShell Scripting in a Month of Lunches by Don Jones and Jeffery Hicks
Before you sit down and start coding up a function or a class, you need to do some thinking about its design. We frequently see toolmaking newcomers charge into their code, and before long they’ve made some monstrosity which is harder to work with than it should be. In this article we’re going to lay out some of the core PowerShell tool design principles, and help you stay on the path of Toolmaking Righteousness. We’ll include some concrete examples.
From Get Programming with F# by Isaac Abraham
This article provides an overview of different “levels” of unit testing, and how and where they’re appropriate in F#. We’ll also discuss different forms of unit testing practices, including test driven development (TDD).
From Learn PowerShell Scripting in a Month of Lunches by Don Jones and Jeffery Hicks
We see a lot of people jump into PowerShell scripting much the same way they’d jump into batch files, VBScript, or Python. Nothing wrong with that – PowerShell is able to accommodate a lot of different styles and approaches, but you end up working harder than necessary unless you take a minute to understand how PowerShell really wants to work. We believe that toolmaking is the real way to use PowerShell.
From ASP.NET Core in Action by Andrew Lock
The word middleware is used in a variety of contexts in software development and IT, but it’s not a particularly descriptive word – so, what is middleware? This article discusses the definition of middleware in ASP.NET Core and how they can be used.
From Concurrency in .NET by Riccardo Terrell
In this article, you’re going to implement one of the most common coordination techniques—the pipeline pattern. In general, a pipeline is composed of a series of computational steps, organized as a chain of stages, where each stage depends on the output of its predecessor and usually performs a transformation on the input data.
From Concurrency in .NET by Riccardo Terrell
In this article, we discuss the need for concurrency, common issues specific to developing concurrent applications in either imperative or object-oriented programming (OOP) and functional programming, and why the functional programming paradigm is ideal for solving common concurrency issues.
From Reactive Applications with Akka.NET by Anthony Brown
Akka.Net provides several implementations of the core routing logic to allow for a variety of techniques for distributing messages through the router to its routees. These routers allow for a wide variety of behaviours which ultimately allow us to continue to build applications that remain responsive even under intense load. In this article, we’ll look at the routers included with Akka.Net and the advantages they provide.
