I love updates to C# that make my life as a developer easier an dbetter. Some are great - interpolation? YES! Auto-properties
I just came acrtoss, because VS told me, about a range operation en lieu of Substring. This is cool.
var variable = originalString.Substring(starts, ends - starts);
turns into
var variable = originalString[starts..ends];
OK - that's sweet. Now I need to remeber to do it instead of magically fast fingers typing out that subsstring function for years!
