receiving error CS1644
I am receiving the following error when trying to compile the code:
error CS1644: Feature `declaration expression' cannot be used because it is not part of the C# 6.0 language specification

That's an interesting error message. It indicates that the compiler correctly identified what you were trying to do (a declaration expression), but didn't perform it because it is a version 6 compiler. I believe that feature was originally planned for version 6 but wasn't introduced into the language until version 7.3.
So for now, keep this C#6.0 compiler happy by declaring your variable before the expression it is used in:
int minutes; int.TryParse(entry, out minutes);
You could also change "TryParse" into a plain "Parse" since you are not using the return value:
int minutes = int.Parse(entry);
