Oddly enough, This works as expected in ISE but not the console.

This is true in interactive shell mode. When a line continuation character is displayed (">>"), if an empty line (or a line containing all spaces -- I presume it's actually a line containing all whitespace, but I didn't test) is entered, then the shell "swallows" the line. So...

$s = @'
aa

bb

cc
'@

is actually stored as

$s = @'
aa
bb
cc
'@

This error exists for both single and double quoted here-strings.

When executing a script file, this does not occur.

If needed add a backticks in the empty line:

$string = @"
Line 1
`
Line 3
"@
