c# - How can I make EF Core database first use Enums?

Question

I'm using EF Core with database-first approach using the "Scaffold-DbContext"-command to generate my DbContext / Entities.

How can I instruct Scaffold-DbContext that a certain field in a certain table should generate code to use an Enum instead of just an int?

This is how you used to do it in regular EF: https://www.devu.com/cs-asp/lesson-69-mapping-enum-types-entity-properties-framework-designer/

Example

This enum is already defined in code:

public enum StateEnum {
  Ok = 1,
  Fail = 2
}

This is what Scaffold-DbContext gives me

public partial class Foo
{
    public int Id { get; set; }
    public int State { get; set; }
}

This is what I want it to create:

public partial class Foo
{
    public int Id { get; set; }
    public StateEnum State { get; set; }
}

Doesn't value conversion in EF Core 2.1 do what you need now?

https://docs.microsoft.com/en-us/ef/core/modeling/value-conversions

Quick Example:

  entity.Property(e => e.MyEnumField)
            .HasMaxLength(50)
            .HasConversion(
                v => v.ToString(),
                v => (MyEnum)Enum.Parse(typeof(MyEnum),v))
                .IsUnicode(false);
