1.You can create inline functions,
Example: public int addNumbers(int a,int b) => a b;
2. You can declare static using,
Example: using static System.Math;
This would simplify the usage of Mathematical functions like Math.Pow(a,b). Instead of Math.Pow(a,b) you could use Pow(a,b)
3. It is now possible to declare the auto-properties,
Example: public string FirstName { get; set; } = "Ervis";
