I have following configuration to map existing DB:
this.Property(x => x.PafAddress1).HasColumnName("PAF_Address1").IsOptional().HasMaxLength(511);
After upgrade to EF 6.1.0
I have now error:
The item with identity 'PAF_Address1' already exists in the metadata collection.
Parameter name: item
How to solve that issue and map such existing column to the model in new 6.1.0
