Resharper suggesting conversion to Abstract Class

Hello.

In an ASP.NET MVC project I have a set of DTO classes I use to return data from the Service layer to the Controller.

Here's an example of the DTO class:

     public class ClaimDTO
     {
          public int ClaimId { get; set; }
          public int CustomerId { get; set; }
          public string CustomerName { get; set; }
     }

And I return data like this:

     ClaimDTO claimDTO = _claimService.GetClaim(claimId);

My Service does the following (using AutoMapper to map the EF entity to the DTO:

          public ClaimDTO GetClaim(int claimId)
          {
               try
               {
                    var claim = _claimRepository.Fetch().SingleOrDefault(c => c.ClaimId == claimId);
                    return Mapper.Map<Claim, ClaimDTO>(claim);
               }
               catch (Exception ex)
               {
                    throw ex;
               }
          }

Resharper is suggesting that I make ClaimDTO an Abstract class as it is never instantiated.  Is this correct?

Apologies if this is not the correct forum for this sort of question.

Kind regards,

Ben
