non primary key relation

Hello.

I have a view, called "OperationAlternative".

namespace idee5.Dispatcher.Model.DAL {
    public class OperationAlternative {
        [Key]
        public virtual int WorkOrderId {
            get;
            set;
        }

        public virtual int? WorkplaceId {
            get;
            set;
        }

        /// <summary>
        /// Highest rank means highest efficiency
        /// </summary>
        [Required]
        public virtual char EfficiencyRank {
            get;
            set;
        }

        [Key]
        public virtual int OperationId {
            get;
            set;
        }

        [Required]
        public virtual uint SequenceNumber {
            get;
            set;
        }

        // association properties
        // association:
        public virtual Workplace Workplace {
            get;
            set;
        }

        // association: CurrentOperation
        public virtual Operation Operation {
            get;
            set;
        }

    }
}

This is the metadatasource part:

public void PrepareOperationAssociationConfigurations(MappingConfiguration<Operation> configuration) {
    configuration.HasAssociation(x => x.MaterialComponents).WithOpposite(x => x.Operation).HasConstraint((m, d)=>d.OperationId == m.Id).IsManaged().IsDependent();
    configuration.HasAssociation(x => x.Transactions).WithOpposite(x => x.Operation).HasConstraint((m, d)=>d.OperationId == m.Id).IsManaged().IsDependent();
    configuration.HasAssociation(x => x.MessageEvents).WithOpposite(x => x.Operation).HasConstraint((m, d)=>d.OperationId == m.Id).IsManaged().IsDependent();
    configuration.HasAssociation(x => x.CalendarEvents).WithOpposite(x => x.Operation).HasConstraint((m, d)=>d.OperationId == m.Id).IsManaged().IsDependent();
    configuration.HasAssociation(x => x.OperationAlternatives).HasConstraint((d, m)=>d.WorkOrderId == m.WorkOrderId && d.SequenceNumber==m.SequenceNumber);
    configuration.HasAssociation(x => x.AllowedWorkplaces).HasConstraint((d, m)=>d.WorkOrderId == m.WorkOrderId && d.SequenceNumber==m.SequenceNumber);
    configuration.HasAssociation(x => x.OperatingResource).WithOpposite(x => x.OperationsAsOpRes).HasConstraint((d, m)=>d.OperatingResourceId == m.Id);
    configuration.HasAssociation(x => x.CycleUoM).WithOpposite(x => x.Operations).HasConstraint((d, m)=>d.CycleTimeUoM  == m.Id).IsManaged();
    configuration.HasAssociation(x => x.Workplace).WithOpposite(x => x.Operations).HasConstraint((d, m)=>d.WorkplaceId == m.Id);
    configuration.HasAssociation(x => x.WorkOrder).WithOpposite(x => x.Operations).HasConstraint((d, m)=>d.WorkOrderId == m.Id).IsManaged();
}

 

Starting the application I getthis error message:

The field 'Operation_operationAlternatives' of class 'idee5.Dispatcher.Model.DAL.OperationAlternative' references a primary key field '<WorkOrderId>k__BackingField' of class 'idee5.Dispatcher.Model.DAL.Operation' that could not be found. --> DispatcherEntities/namespace[idee5.Dispatcher.Model.DAL]/class[Operation]/field[operationAlternatives]/collection/inverse="{auto}"/db-ref="<WorkOrderId>k__BackingField"

Any ideas what I did wrong?

Kind regards

HasConstraint seems to need a primary key. So I rephrase my question:

How can I tell Data Access that there is a connection betweeen OperationAlternative and Operation through WorkOrderId and SequenceNumber? Which are not the primary key of Operation.
