When "Send to interactive" raises exception, the FSI prompt disappears

[abelbraaksma]

Repro

• Type a piece of code that raises an exception, say let x = 12/0
• Right-click, select "Send to interactive" (or hit your key combination)
• FSI will show exception, but will not show the prompt anymore

Occasionally this behavior cannot be observed the first time, but only after a few tries.

Just hitting Enter in the FSI window does not bring back the prompt.

Expected

The prompt should show. If you type the throwing code directly in FSI, it works as expected.

Actual

No prompt:

Severity

Low

Versions

Visual Studio 2012, 2013, 2015. F# 3.0, 4.0.

Workaround

Sending something else to FSI that is valid, will restore the prompt. Typing something in FSI (ignore there is no prompt) works as well.

I am not aware of a workaround that keeps the prompt intact at all times.
