ASP.NET Transferring data to postgresql - asp.net

Question

I can't understand why the data is not transferred to the database
There is a controller
public class PeopleController : Controller
{
private readonly string ConnectionString = "Host=localhost;Port=5432;Database=CrudDb;Username=postgres;Password=12345;Maximum Pool Size=100";
[HttpGet]
public IActionResult Create()
{
return View();
}
[HttpPost]
public IActionResult Create(People people)
{
if (ModelState.IsValid)
{
IDbConnection con;
string insertQuery = "INSERT INTO people(name, phone) VALUES(#Name, #Phone)";
con = new NpgsqlConnection(ConnectionString);
con.Open();
con.Execute(insertQuery, people);
con.Close();
return RedirectToAction(nameof(Index));
}
return View(people);
}
}
There is a model for her
public class People
{
public int Id { get; set; }
public string Name { get; set; }
public int Phone { get; set; }
}
And there is a page
<form asp-action="Contacts">
<div asp-validation-summary="ModelOnly" class="text-danger"></div>
<div class="form-group">
<label asp-for="Name" class="col-form-label">Имя</label>
<input asp-for="Name" class="form-control" />
<span asp-validation-for="Name" class="text-danger"></span>
</div>
<div class="form-group">
<label asp-for="Phone" class="col-form-label">Телефон </label>
<input asp-for="Phone" class="form-control" />
<span asp-validation-for="Phone" class="text-danger"></span>
</div>
<div class="form-group p-4">
<input type="submit" value="Создать" class="btn btn-outline-success btn-sm" />  
</div>
</form>
It does not issue any errors, I enter data on the page, but this data is not transmitted to the database. From libraries, Dapper and Npgsql are connected
