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 Resharper 5. see answer below.
-In Resharper 4 use Resharper/Options/Languages/Common/Naming Style Choose the radio "Override common settings" this enables the button "Manage Abbreviations"
For a specific language
