Mastering Generic Constraints in C# | class, struct, new(), interface
In this video, we take a deep dive into Generic Constraints in C# and understand how they improve type safety, flexibility, and design in generic programming.
We start from the basics and gradually move toward advanced usage scenarios, including real-world examples and commonly used constraints such as class, struct, new(), interfaces, and base class constraints.
You will also learn how constraints work with interfaces like IComparable and INumber, and how they shape the behavior of generic types in .NET.
By the end of this video, you’ll have a clear mental model of when and why to use generic constraints in your C# applications.
