Resolve Issue With My C# Code

I'm using EF with a code-first approach, this is what I have set-up:

public void Configure(EntityTypeBuilder<OrderLine> builder)

{

[login to view URL](l => new {[login to view URL], [login to view URL]});

}

but I'm getting the error

[login to view URL]: The instance of entity type 'OrderLine' can not be tracked because another instance with the same key value for {'OrderLineId', 'empId' } is already being tracked

If I check the database in the OrderLine table the orderNumber I'm pulling data for does not exist, however the empId exists in that table associated with a different orderNumber.

Do I need to change my Configure method for this?
