I am getting the following warning from Code Analysis in VS2010
CA1704 : Microsoft.Naming : Correct the spelling of \'Ps\' in member name \'MyClas
It's being rejected because it's flagged as an unrecognized word in the "root" custom dictionary in Code Analysis installation folder (usually %ProgramFiles%\Microsoft Visual Studio 10.0\Team Tools\Static Analysis Tools\FxCop). You'll need to remove it from the root dictionary unrecognized list before adding it as a recognized word in a project-specific dictionary will take effect.
