Preferably not using attributes.

Solution

  • If you're building your entities using the fluent interface rather than using attributes over the properties, you may be able to use the DatabaseGenerationOption class (from EntityFramework.dll, in the System.ComponentModel.DataAnnotations namespace). I've not tested it, but this is what it would look like:

    modelBuilder
    .Entity<Foo>()
    .Property(f => f.Id)
    .HasDatabaseGeneratedOption(DatabaseGeneratedOption.None);
