I am using ReSharper 4.5, and what often happens when I am converting explicit properties into auto-properties, is that I will accidentally chose \"Add XX to abbreviations list\
In the 5.0 beta, it's similar
ReSharper/Options/Languages/Naming Style/Advanced Settings...
Then there's a box at the bottom called "Edit abbreviations as plain text"
In resharper 5.X versions, please use "Reset to Defaults" to remove already added abbreviations.
ReSharper/Options/Code Editing/C#/C# Naming Style/Override to common settings/Reset to Defaults
@user1107632: 2D and 3D are not a valid variable and you are not going to use anyway.
