C# 12 brings some amazing new features that make coding more expressive and efficient.
Collection expressions make it easier to work with collections:
var numbers = [1, 2, 3, 4, 5];
var moreNumbers = [.. numbers, 6, 7, 8];
Default parameters for lambda expressions:
Func<int, int> add = (x, y = 10) => x + y;
Console.WriteLine(add(5)); // Output: 15
Type visibility limited to the file:
file class InternalHelper
{
public static void HelperMethod() { }
}
C# 12 continues to make the language more powerful and expressive. These features will help you write cleaner, more maintainable code.
