According to GPT4, "A .NET C# constructor is a special kind of method in C# used to create and initialize objects from a class. When you create a new instance of a class, the constructor sets up the initial state of the object, like setting initial values for its properties or fields. Constructors have the same name as the class and do not have a return type, not even void." I couldn't have said it better myself.

Why not just say "public string Foo;" instead of saying "public Foo(string name)?

Because constructors don't have return types public string Foo would imply a method named Foo that returns a string whereas a constructor is always [optional access modifier] [name]([parameters])
