string.Format($"{0}", "my text")The above code looks fine at first glance, but its return value is "0" - not "my text" as you might expect!
This can be hard for a human to see, but R# can probably detect this easily, since it already detects format strings. Using an interpolated string as a format strings should probably be a warning - it seems much more likely to be a mistake than intentional. (How often do you really need to "double-format" a string?)
