In MS.NET:

type 'System.String'.

e`1 shopProductTracks) in c:\dev\lockerTeam\sevendigital-inbox-backfill\src\Seve
nDigital.Inbox.Backfill\Repositories\TrackRepository.cs:line 90

Comment 1 Zoltan Varga 2013-05-29 11:22:32 UTC
This has some performance costs, so its not enabled by default.  Try running with --debug=casts.
Comment 2 Andres G. Aragoneses 2013-05-29 12:08:28 UTC
Shouldn't it be already available with --debug? (Because debug is anyway already slower than non debug)
Comment 3 Zoltan Varga 2013-05-29 19:26:12 UTC
--debug only slows down JITting, --debug=casts slows down execution.
Comment 4 Andres G. Aragoneses 2013-05-29 19:27:04 UTC
I see.

What about giving a hint about "--debug=casts" in the exception message?
