Entity Framework Core 2.0 default value for common property in many tables

I am doing code first EF Core 2.0 migrations. I have few columns which are common across all entities. All entities inherit this class as shown below.

How do I set the default value for CreateDate as current date, CreateBy as 'System' and IsDeleted as 0?

public class BaseEntity
{
    public DateTime CreateDate { get; set; }

    public string CreateBy { get; set; }

    public bool IsDeleted { get; set; }
}

I know how to do this for a single property. ie.

class MyContext : DbContext
{
    public DbSet<CaseDetails> CaseDetails{ get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<CaseDetail>()
            .Property(b => b.CreateDate)
            .HasDefaultValueSql("getutcdate()");

        modelBuilder.Entity<CaseDetail>()
            .Property(b => b.CreateBy)
            .HasDefaultValue("System");

        modelBuilder.Entity<CaseDetail>()
            .Property(b => b.IsDeleted)
            .HasDefaultValue("0()");
    }
}

Can anyone help me how to do this in an efficient way so it will be available for all entities?

Thanks
