Remove serial column creation Entityframework + Npgsql

Ola, I am creating an application using Fluent API + Entityframework. But in my domain classes when determining that a property is PK it automatically defines it as serial, I would not like to get this behavior because it will automatically create a SEQUENCE for each PK field of my tables. How do I remove this validation and define that when the field is a primary key I do not want it to be serial but only integer?

Thank you

  • Although I answered the question for you (if it’s the right one, mark it as correct), I would like to know what your scenario is, or concern about not using IDENTITY ("serial") for your Keys. This is usually indicated.

You need to mark the column to not generate the sequence. This should solve for you:

modelBuilder
    .Entity<*nome_da_entidade*>()
        .Property(m => m.*campo*)
             .HasDatabaseGeneratedOption(DatabaseGeneratedOption.None);

Another way I imagine to be automatic would be to include the attribute below directly in the property:

[System.ComponentModel.DataAnnotations.Schema.DatabaseGenerated(
    System.ComponentModel.DataAnnotations.Schema.DatabaseGeneratedOption.None)]

Or, rather, add System.ComponenteModel.DataAnnotations.Schema to its clauses using and just like that:

[DatabaseGenerated(DatabaseGeneratedOption.None)]
