Empty interpolated string CS-W1000

String interpolation requires that you specify the string that is to be interpolated and the required arguments. Failing to specify the required arguments may result in an ill-formatted string. Because it is possible that such strings can critically alter the behaviour and control-flow of the program, it is suggested that you fix it as soon as possible.

Bad Practice

var pi = 3.14
var message = $"The value of `pi` is pi";

Recommended

var pi = 3.14
var message = $"The value of `pi` is {pi}";
