Question

I am creating a reusable library using .NET Core (targeting .NETStandard 1.4) and I am using Entity Framework Core (and new to both). I have an entity class that looks like

Answer 1

Here's something I used

Model

public class FacilityModel 
{
    public string Name { get; set; } 
    public JObject Values { get; set; } 
}

Entity

[Table("facility", Schema = "public")]
public class Facility 
{
     public string Name { get; set; } 
     public Dictionary Values { get; set; } = new Dictionary();
}

Mapping

this.CreateMap().ReverseMap();

DBContext

base.OnModelCreating(builder); 
        builder.Entity()
        .Property(b => b.Values)
        .HasColumnType("jsonb")
        .HasConversion(
        v => JsonConvert.SerializeObject(v),
        v => JsonConvert.DeserializeObject>(v));
