Starting from C# 6.0, you can use string interpolation expressions instead of calling String.Format(). If you pass a lot of arguments to the String.Format() method, the string becomes difficult to understand. Compared to String.Format(), interpolated string expressions allow inserting variables directly in the string.

var greeting = string.Format("Hi {0}! How do you feel at {1}?", name, location);
                

var greeting = $"Hi {name}! How do you feel at {location}?";
