Learn how to use C# primary constructor to simplify class definitions. Practical examples, best practices, and tips for cleaner C# code. Start now! What Is a C# Primary Constructor? A C# primary constructor lets you declare constructor parameters directly in the class or struct declaration, eliminating boilerplate code that developers have written for decades. Introduced in C# 12 (with .NET 8), primary constructors for classes and structs build on a feature that records have enjoyed since C# 9. If you have ever written a class with a constructor that does nothing but assign parameters to fields, you already know the pain. A typical C# class constructor requires you to declare private fields, write a constructor method, and assign each parameter — often tripling the lines of code for a simple data holder. Primary constructors in C# fix this by letting you define parameters right where you define the class. Why Primary Constructors Matter in Modern C# Before C# 12, even a...
