Description Mikayla Hutchinson [MSFT] 2013-07-18 18:42:23 UTC
Error tooltips are often not displayed e.g. unresolved overloads, and the following pango error is printed to the log:

Comment 1 Mike Krüger 2013-07-19 00:50:43 UTC
Which error is broken ? 
I think this is 100% reproduceable therefore I need the exact case.
Comment 2 Mikayla Hutchinson [MSFT] 2013-07-20 22:39:57 UTC
Here's an easy repro:

Task.Factory.StartNew (new List<int> ());
Comment 3 Mike Krüger 2013-07-23 02:36:14 UTC
fixed
Comment 4 Nischal 2014-01-20 06:08:15 UTC
Checked with the code line mentioned in comment 2 and now error tooltips are appearing correctly. Screencast: http://screencast.com/t/LWq5pnPO

Please let me know in case additional areas/pointers I need to check.
