Answer 1

Value converters are now supported in EntityFrameworkCore 2.1 This allows you to treat Enums as strings in your database and have them correctly convert to Enums in your model.

You do this with a value converter. You can create your own but EF Core 2.1 comes with some pre-defined value converters out of the box. One of these is the EnumToString value converter.

So given the following:

public class Rider
{
    public int Id { get; set; }
    public EquineBeast Mount { get; set; }
}

public enum EquineBeast
{
    Donkey,
    Mule,
    Horse,
    Unicorn
}

Use the default converter like this:

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder
        .Entity<Rider>()
        .Property(e => e.Mount)
        .HasConversion<string>();
}

Or if you prefer using attributes on your model classes like this:

public class Rider
{
    public int Id { get; set; }

    [Column(TypeName = "nvarchar(24)")]
    public EquineBeast Mount { get; set; }
}

Answer 2

This worked for me. I am using "EntityFramework.MicrosoftSqlServer": "7.0.0-rc1-final" in project.json. I had to run ef migrations database update as part of pushing the model.

public class Person
{
    public int PersonId { get; set; }
    public string LastName { get; set; }
    public string FirstName { get; set; }
    public int PersonTypeId { get; set; }
    public PersonType PersonType { get; set; }
    public ActiveType ActiveType { get; set; }
}

public enum ActiveType
{
    Active = 0,
    Inactive = 1
}
