Description Dylan Borg 2011-08-30 11:38:49 UTC
The function Microsoft.VisualBasic.CompilerServices.LikeOperator.LikeString does not confirm a match when it should do so in the case of patterns beginning with a '-' meant to match the latter character.

The bug was observed when the following parameters were passed:
1. "-1d"
2. "-#*"
3. OptionCompare.Binary

The Microsoft version of the Microsoft.VisualBasic.dll library does not exhibit this bug in the before mentioned function. While the Mono version does have the bug. The mentioned parameters should yield True while when I tried this with Mono on Windows and Linux (Mono 2.10.1) it gave out False.
