This video draws the line under the diverse needs and requests we encounter when enforcing the validity of C# records. You will learn a set of approaches, from no validation at all in proper values, over property assignment validation, all the way to constructor validation of the sort we apply to regular classes.
There will be talking about record structs, which require double attention thanks to their mandatory default constructor as well as the default keyword that affects their creation.
There will be a touch of alchemy in between. We will demonstrate compile-time validation, which requires no code to execute at run time. Yet, every record instance will be created valid, with a 100% guarantee.
You decide which route to take from here. Still, be advised that not all routes are either safe or comfortable. Learn your tools well, and your code will flourish.

👨 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.❤️
