The database is not created (ASP.NET Core + EF Core), what's the problem?

Question

C++ / C#

in appsettings

"ConnectionStrings": {
    "DefaultConnection": "Server=(LocalDb)\\MSSQLLocalDB; Database=test; Trusted_Connection=True;"
  },

In startup

public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllersWithViews();

            string connection = Configuration.GetConnectionString("DefaultConnection");
            services.AddDbContext<AppDbContext>(x => x.UseSqlServer(connection));
        }

Context:

public DbSet<People> Peoples { get; set; }

        public AppDbContext(DbContextOptions<AppDbContext> options) 
            : base(options) 
        {
            Database.EnsureCreated();
        }

Should the database be created on the first run? This is not happening.
Nothing else changed or added.
