Creating tables for multiple DbContext's using the same database

I'm trying to implement multiple DbContext's targeting the same database.

It works when calling DataBase.EnsureCreated() on the first DbContext object, but it doesnt create tables for the remaining objects. After Init.Initalize() I want the database to contain two tables named Clients and Addresses

Initalize database:

public static class Init
{
    public static void Initalize(BaseDbContext[] contexts, Config.Options.Environments environment)
    {                     
        if (environment == Config.Options.Environments.Development)
        {
            contexts[0].Database.EnsureDeleted();

            foreach(BaseDbContext context in contexts)
            {
                context.Database.EnsureCreated();
            }

            var clients = new Client[]
            {
                new Client() { Key = Guid.NewGuid(), Name = "Smokers.no", DisplayName = "Smokers.no", Email = "post@smokers.no", LogoFilename = "logo.jpg" }
            };

            foreach(BaseDbContext context in contexts)
            {
                if (context.GetType().Equals(typeof(Data.SharedDbContext)))
                {
                    var cntx = context as Data.SharedDbContext;
                    foreach (Client client in clients) { cntx.Clients.Add(client); }
                    cntx.SaveChanges();
                }
            }


        }
        else
        {
            foreach(BaseDbContext context in contexts)
            {
                context.Database.EnsureCreated();

                if (context.GetType().Equals(typeof(Data.SharedDbContext)))
                {
                    var cntx = context as Data.SharedDbContext;

                    if (cntx.Clients.Any())
                    {
                        return;
                    }
                }
            }
        }
    }
}

BaseDbContext:

public class BaseDbContext : DbContext
{
    public BaseDbContext(DbContextOptions<BaseDbContext> options) : base(options) { }
}

SharedDbContext:

public class SharedDbContext : BaseDbContext
{
    public SharedDbContext(DbContextOptions<BaseDbContext> options) : base(options) { }

    #region DbSets
    public DbSet<Client> Clients { get; set; }
    #endregion
}

MailerDbContext:

public class MailerDbContext : BaseDbContext
{
    SharedDbContext _context;

    public MailerDbContext(DbContextOptions<BaseDbContext> options, SharedDbContext context) : base(options)
    {
        _context = context;
    }

    public SharedDbContext LCToolsContext
    {
        get
        {
            return _context;
        }
    }

    #region DbSets
    public DbSet<Address> Addresses { get; set; }
    #endregion
}
