Impossible to continue using F# Interactive (FSI) if you miss-escape a string

[abelbraaksma]

Try something like the following line in F# Interactive (System must be open):

 Uri.IsWellFormedUriString ("c:\", UriKind.Absolute);;

Repro steps

See above.

Expected behavior

Somehow being able to continue using F# Interactive, with Ctrl-C, or typing more ";;" or more enters.

Actual behavior

I didn't quite find a way to continue. This is probably expected behavior (the string is unfinished), but it would be nice to have a way to cancel your current input, whatever it is (one alternative is to reset the FSI, but that will loose your history and opens).

Known workarounds

Find a way to close the quote. In this case, once I realized the error after not understanding the blank lines I got after hitting enter, I typed the " (double quote char) and I got my console back.

You have to send-to-interactive just the " character.

I do agree this should be improved.

[abelbraaksma]

Yes, but since there's no syntax highlighting, this is more baffling than it should be

This is actually a duplicate of #830, which is tagged as a bug. Let's try to re-tag that issue appropriately if we think of it as a bug or feature improvement.
