Service

#EF : DbEntityValidationException - How can I easily tell what caused the error?

While calling  SaveChanges  on my  DbContext , I get the following exception: System.Data.Entity.Validation.DbEntityValidationException: Validation failed for one or more entities. See 'EntityValidationErrors' property for more details. This is all fine and dandy, but I don't want to attach a debugger every time this exception occurs. More over, in production environments I cannot easily attach a debugger so I have to go to great lengths to reproduce these errors. How can I see the details hidden within the  DbEntityValidationException ? Answer :  The easiest solution is to override SaveChanges on your entities class. You can catch the DbEntityValidationException, unwrap the actual errors and create a new DbEntityValidationException with the improved message.
