无法使用 SqlQuery 从存储过程获取数据

问：

这是存储过程：

public partial class AddedSP: DbMigration
{
    public override void Up()
    {
        CreateStoredProcedure("dbo.GetTopRecommendingUsers"
          // These are stored procedure parameters
          ,null,
          // Here is the stored procedure body
          @" SET NOCOUNT ON;
             BEGIN
             SELECT promoter.Id, promoter.Email, promoter.PhoneNumber, promoter.UserName, promoter.FirstName, promoter.LocationId, promoter.RegionId, promoter.ProfilePhotoId, promoter.LastName, COUNT(u.RecommendedById) AS Recommendations
             FROM AspNetUsers AS promoter 
             INNER JOIN AspNetUsers AS u ON u.RecommendedById = promoter.Id
             GROUP BY promoter.Id, promoter.Email, promoter.PhoneNumber,promoter.RegionId, promoter.UserName, promoter.LocationId, promoter.ProfilePhotoId, promoter.FirstName, promoter.LastName
             ORDER BY COUNT(u.RecommendedById) DESC
             END");
    }
    public override void Down()
    {
        DropStoredProcedure("dbo.GetTopRecommendingUsers");
    }
} 

这是我的班级：

public class RecommenderViewModel
{
    public string Id { get; set; }
    public string Email { get; set; }
    public string PhoneNumber { get; set; }
    public string UserName { get; set; }
    public string FirstName { get; set; }
    public string LocationId { get; set; }
    public string RegionId { get; set; }
    public string ProfilePhotoId { get; set; }
    public string LastName { get; set; }
    public int Recommendations { get; set; }
}

这是进行调用的方法：

    public List<RecommenderViewModel> GetTopRecommendingUsers()
    {
        List<RecommenderViewModel> model = new List<RecommenderViewModel>();
        using (var context = new ApplicationDbContext())
        {
            model = context.Database.SqlQuery<RecommenderViewModel>("GetTopRecommendingUsers").ToList();
        }
        return model;
    }

但是我在方法的模型变量中得到一个空列表（Count=0）。GetTopRecommendingUsers()

我做错了什么？
