Hello,

Maybe it's not related to Telerik but ig anyone can give me a little clue about those errors I will be very glad.  I use Entity Framework.  Those errors are from the Event Viewer of my server.

WebHost failed to process a request.

 Exception: System.ServiceModel.ServiceActivationException: The service '/Services/mes-Web-Services-descriptionsDomainService.svc' cannot be activated due to an exception during compilation.  The exception message is: The type 'mes.Web.Fiches' has been mapped more than once.. ---> System.Data.MappingException: The type 'mes.Web.Fiches' has been mapped more than once.
