Dapper - Query multiple models

My query involves multiple tables and from what I've read on Dapper, I can only find examples, that I understand at least, that query one model.

Below are my 3 classes under the Models folder:

public class User
{
    public string UserName { get; set; }
    public string UserId { get; set; }
    public string Email { get; set; }
    public string Phone { get; set; }
}

public class Date
{
    public string UserName { get; set; }
    public string UserCode { get; set; }
    public string LastLogin { get; set; }
}

public class Photo
{
    public class UserName { get; set; }
    public string UserId { get; set; }
    public string PhotoUrl { get; set; }
}

In my repository I have my connection code and then a method to get all the information I need, however this method is tied to the User model only but I also need to retrieve the photo and when I try to make a compound class so I can the User and Photo models in the view, it gives me an error saying it expects only the User DataView.

public List<User> GetAll()
{
    using (SqlConnection cn = new SqlConnection(connectionString))
    {
        var allResults = cn.Query<User>("SELECT UserName, Email, Phone, (SELECT TOP 1 PhotoPath FROM Photo WHERE User.UserId = Photo.UserId) FROM User)
