We've all been there: You design a slick C# method, but then it might need to return... null. How many times have you crafted a method, sometimes a complex one, only to encounter the inevitable predicament of possibly returning null?
The ripples from this single decision can create waves in your code. Suddenly, there's a surge in downstream complexity. Pesky null checks, null propagation, and null coalescing start popping up everywhere and before you know it, you're deep-diving into a sea of operators, attempting to keep your code stable. The once crisp and clean code begins to resemble a tangled web. And readability? Well, it is long gone already!
But what if we could turn the tables and say that every method you design must always return an object, a meaningful one? This isn't just about avoiding the null trap; it's about transforming the way you think about and design methods in C#.
In this video, we will dissect a piece of realistic demo code to showcase how you can improve the domain model, making it not just resilient but also expressive. The secret is in removing a nullable return from a method! The consumers will need not wrestle with potential nulls is over. The calling code will suddenly attain simplicity, clarity, and elegance and - why not say? - only the happy path will remain!

👨 About Me 👨
Hi, I’m Zoran, I have more than 20 years of experience as a software developer, architect, team lead, and more. I have been programming in C# since its inception in the early 2000s. Since 2017 I have started publishing professional video courses at Pluralsight and Udemy and by this point, there are over 100 hours of the highest-quality videos you can watch on those platforms. On my YouTube channel, you can find shorter video forms focused on clarifying practical issues in coding, design, and architecture of .NET applications.❤️
