Introduced in 0.26.8
Interpolated string (with $ prefix, such as $"foo") is used without embedded F# expression (e.g. $"{foo}" where foo is some value).
Or string formatting function such as sprintf or failwithf is used without interpolation.
Usage of interpolated string without embedded F# expression(s) may indicate that the expression was intended to be used but wasn't used by mistake.
Use regular string or embed F# expression using curly braces ({}).
Use failwith instead of failwithf if no formatting/interpolation is needed.
