Do you use string interpolation when formatting strings

String Interpolation - greatly reduces the amount of boilerplate code required when working with strings Formatting strings on the fly was previously a task which required a stack of boilerplate code

var s = String.Format("Profit is ${0} this year", p.TotalEarnings - p.Totalcost);

var s = "Profit is ${p.TotalEarnings - p.Totalcost} this year";
