I need some help with the select tag helper in ASP.NET Core.

I have a list of employees that I'm trying to bind to a select tag helper. My employees are in a List<Employee> EmployeesList and selected value will go into EmployeeId property. My view model looks like this:

public class MyViewModel
{
   public int EmployeeId { get; set; }
   public string Comments { get; set; }
   public List<Employee> EmployeesList {get; set; }
}

My employee class looks like this:

public class Employee
{
   public int Id { get; set; }
   public string FullName { get; set; }
}

My question is how do I tell my select tag helper to use the Id as the value while displaying FullName in the drop down list?

<select asp-for="EmployeeId" asp-items="???" />

I'd appreciate some help with this. Thanks.
