How not to use a magic string with IsInRole in Silverlight RIA?
===

I have extended the `UserBase` class in `System.ServiceModel.DomainServices.Server.ApplicationServices` in my Silverlight RIA, and yes people still use Silverlight, and I was wondering what the best practice would be regarding `IsInRole(@"domain\groupName")` and how I might get away from using a hard-coded group name? 

I am using Windows auth and an Authentication DomainService.
