How to use out in c#7 with visual studio 2017

In c#7 you can use out keyword in new way , let's take an example

i need to get my name by out keyword in c#6 your code will be like this

public static void OldWay()
{
     string firstName;
     string lastName;
     MyName(out firstName, out lastName);

     Console.WriteLine($"My Name is :{ firstName} {lastName}  => Old way");
}

now in c#7 you don't need to define variables alone you just define it when you pass it to the method something like this

public static void CSharp7Way()
{
    MyName(out string firstName, out string lastName);

    Console.WriteLine($"My Name is :{ firstName} {lastName}  => c#7 way");
}

when you run you will see the magic and the same result :)
