I often use Switch with enums. JaredPar's answer is good, but it doesn't work for me (possibly because i am using ReSharper).

What is working for me: after creating a Switch statement based on some enum, i click my mouse at begining of word "Switch", then i press ALT+ENTER and select "Add switch statement for bla-bla-bla...". This will generate all cases for all possible enum values.
