In software development, there’s a silent debt that accrues interest over time, often hidden beneath layers of code and decisions made in haste or ignorance. This debt is aptly termed technical debt. Much like the german proverb, “Wer den Pfennig nicht ehrt, ist den Taler nicht wert”, (or the english equivalent, “A penny saved is a penny earned”) technical debt reminds us that small oversights or compromises in the present can snowball into significant challenges down the road. This article critically examines the parallels between financial principles and technical debt, emphasizing the importance of addressing both direct and indirect debt while understanding its distinction from external risks such as hacking or abuse.

In software development, dependencies are inevitable - any project worth its salt relies on various libraries, frameworks, or packages. However, as I found in my own work, managing these dependencies can be an onerous task. Constant updates, new vulnerabilities, and endless manual approvals were draining my time and focus. What if, I thought, these processes could be automated? This thought led to the creation of dependamerge, a GitHub Action designed to free developers from the drudgery of manual dependency maintenance and let us get back to what we do best: building great software.

As developers, we’re often tasked with maintaining and modernizing legacy codebases that were written long before some of the best practices of today—such as nullability annotations—were available. While modern C# now supports nullable reference types, enabling us to avoid the dreaded NullReferenceException, introducing this feature to existing, large codebases can be a challenge.

In this article, I’ll share my step-by-step approach for introducing nullability into a legacy .NET and C# project. You’ll learn how to apply nullability in a controlled, incremental manner using project-level settings, scoped annotations, and file/method-level directives, all while maintaining the integrity of your legacy codebase. After all, modernizing your code doesn’t have to be an all-or-nothing endeavor—gradual change is key to a successful transition. Let’s get started!

In the ever-evolving world of .NET development, managing project configurations effectively is crucial for maintaining a clean and efficient build process. One of the less frequently discussed but highly useful properties is BuildingInsideVisualStudio. This property, when correctly utilized, can streamline your build process and ensure that your project is configured properly depending on the build environment. In this article, we’ll explore the BuildingInsideVisualStudio property with concrete examples and discuss best practices for using it effectively.
