Mid(foo, 1) is equivalent to [foo], if all you want is the character. Similarly Left(1) is [0]. It is faster also, since it does not need to create intermediate strings. Right(1) is a touch more tricky, since it requires something like GetLength() ? [GetLength() - 1] : 0;. A new method, Last() has been added to perform this character extraction. Multiple call sites have been updated to use more efficient/simpler syntax. There are a number of call sites that use on these patterns, but based on the surrounding context we actually need/want a string, so they have not been modified.
