Code Inspection: Use string interpolation expression

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.

Suboptimal code

After the quick-fix

Console.WriteLine(string.Format("this is {0}", z));
Console.WriteLine($"this is {z}");
