C:\Inetpub\wwwroot\EvolutionInternet\ContentManagementSystem\Data\EntityBaseClasses\ KnowledgeBaseItemRatingEntityBase.cs(925): 'EvolutionInternet.ContentManagementSystem.Data.EntityClasses.KnowledgeBaseItemRatingEntityBase.IsNew' hides inherited member 'SD.LLBLGen.Pro.ORMSupportClasses.EntityBase.IsNew'. To make the current member override that implementation, add the override keyword. Otherwise add the new keyword.
This is not stopping the project compiling but is throwing a warning, any ideas? It actually happens for two of the classes!
