Using the 5.0 beta release (from December), I noticed an issue that was fixed in 4.x is back in 5.x...
Declare a literal string by typing:
private string foo = @"|"
Note the cursor is where the | character is, and the closing quote was auto-inserted. Now, if you type a quote character, instead of over-typing the auto-added quote, it inserts a new quote, resulting in this:
private string foo = @""|"
(where | indicates where the cursor is).
