Learn C# primary constructors in C# 12 with practical examples, best practices, and pitfalls. Simplify your class definitions today. If you have written much C#, you know the ritual: declare a private field, add a constructor parameter, assign one to the other, repeat for every dependency. C# primary constructors , introduced in C# 12 with .NET 8, remove that ceremony by letting you declare constructor parameters directly on the class or struct declaration. In this tutorial you will learn how C# primary constructors work, when to use them, how they differ from records, and the pitfalls that catch even experienced developers. What Are C# Primary Constructors? A primary constructor is a set of parameters declared in the header of a class or struct. Those parameters are in scope throughout the entire body of the type, so you can use them in fields, properties, methods, and even other constructors without manually assigning them anywhere.
