Это сработало идеально для меня! Спасибо

я есть два стола News и NewsComments. Я следовал правилам именования

структура NewsComments

public class NewsComment : BaseComment
{
    public int NewsId { get; set; }

    public virtual News News { get; set; }      
}

Но запрос возвращает исключение Неверное имя столбца "News_Id". Я знаю, что это исключение создано, когда в таблице не связаны столбец.

CREATE TABLE [dbo].[NewsComments](
[Id] [int] IDENTITY(1,1) NOT NULL,
[NewsId] [int] NOT NULL,
[Text] [varchar](max) NOT NULL,
[UserId] [int] NOT NULL,
[CommentDate] [datetime] NOT NULL,
[Ip] [varchar](40) NOT NULL, CONSTRAINT [PK_NewsComments] PRIMARY KEY CLUSTERED([Id] ASC )WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]) ON [PRIMARY]

BaseComment

public abstract class BaseComment : BasePersistentEntity, IComment
{

    public int UserId { get; set; }

    public virtual BaseUser User { get; set; }

    [Display(ResourceType = typeof(FrameworkResurce), Name = "CommentText")]
    public string Text { get; set; }


    [Display(ResourceType = typeof(FrameworkResurce), Name = "CommentDate")]
    public DateTime CommentDate { get; set; }


    public string Ip { get; set; }
}

Новости

public class News : BaseContent
{
    [Display(ResourceType = typeof(NewsResurce), Name = "NewsImage")]
    public string NewsImage { get; set; }

    public virtual ICollection<NewsCommentView> CommentViews { get; set; }
}

BaseContent

public abstract class BaseContent : BasePersistentEntity
{
    [Display(ResourceType = typeof(FrameworkResurce), Name = "Keywords")]
    public string Keywords { get; set; }


    [Display(ResourceType = typeof(FrameworkResurce), Name = "TitleTranslit")]
    public string TitleTranslit { get; set; }

    [Required(ErrorMessageResourceType = typeof(FrameworkResurce), ErrorMessageResourceName = "IsTextEmpty")]
    [Display(ResourceType = typeof(FrameworkResurce), Name = "Title")]
    public string Title { get; set; }


    [Display(ResourceType = typeof(FrameworkResurce), Name = "Description")]
    public string Description { get; set; }


    [Display(ResourceType = typeof(FrameworkResurce), Name = "Contents")]
    public string Contents { get; set; }


    [Display(ResourceType = typeof(FrameworkResurce), Name = "DatePublish")]
    public DateTime DatePublish { get; set; }


    [Display(ResourceType = typeof(FrameworkResurce), Name = "AuthorPublish")]
    public string AuthorPublish { get; set; }

    [Display(ResourceType = typeof(FrameworkResurce), Name = "Author")]
    public string Author { get; set; }

    [Display(ResourceType = typeof(FrameworkResurce), Name = "AuthorUrl")]
    public string AuthorUrl { get; set; }


    [Display(ResourceType = typeof(FrameworkResurce), Name = "Views")]      
    public int Views { get; set; }


    [Display(ResourceType = typeof(FrameworkResurce), Name = "Comments")]
    public int Comments { get; set; }


    [Display(ResourceType = typeof(FrameworkResurce), Name = "IsComment")]
    public bool IsComment { get; set; }


    [Display(ResourceType = typeof(FrameworkResurce), Name = "SumVote")]
    public int SumVote { get; set; }


    [Display(ResourceType = typeof(FrameworkResurce), Name = "VoteCount")]
    public int VoteCount { get; set; }

    [NotMapped]
    [Display(ResourceType = typeof(FrameworkResurce), Name = "Rating")]
    public double Rating
    {
        get
        {
            if (VoteCount > 0)
            {
                return Math.Round((float)SumVote/VoteCount, 2);
            }

            return 0;
        }
    }
}

запрос

private IEnumerable<NewsComment> GetComments()
    {
        var news = NewsCommentRepository.AllIncluding(c=>c.User,c=>c.News);
        return news;
    }

private DataRepository<NewsComment> NewsCommentRepository
        {
            get { return DataRepository<NewsComment>.Repository; }
        }

DataRepository

public class DataRepository<T> where T : BasePersistentEntity
{
    public static DataRepository<T>  Repository
    {
        get
        {
            return new DataRepository<T>();
        }
    }

    private readonly SGNContext<T> context = new SGNContext<T>();

    public IQueryable<T> All
    {
        get { return this.context.Table; }
    }

    public IQueryable<T> AllIncluding(params Expression<Func<T, object>>[] includeProperties)
    {
        IQueryable<T> query = this.context.Table;
        return includeProperties.Aggregate(query, (current, includeProperty) => current.Include(includeProperty));
    }

    public T Find(int id)
    {
        return this.context.Table.Find(id);
    }

    public void InsertOrUpdate(T country)
    {
        if (country.Id == default(int))
        {
            // New entity
            this.context.Table.Add(country);
            Save();
        }
        else
        {
            // Existing entity
            this.context.Entry(country).State = EntityState.Modified;
            Save();
        }
    }

    public void Delete(int id)
    {
        var country = this.context.Table.Find(id);
        this.context.Table.Remove(country);
        this.Save();
    }

    private void Save()
    {
        this.context.SaveChanges();
    }
}

Где используется GetComments

    [GridAction]
    public ActionResult AjaxCommentsBinding()
    {
        return View(new GridModel<NewsComment>
        {
            Data = GetComments()
        });
    }

NewsCommentViews

CREATE VIEW [dbo].[NewsCommentViews]
AS
SELECT     dbo.NewsComments.NewsId, dbo.NewsComments.Text, dbo.NewsComments.UserId, dbo.NewsComments.CommentDate, dbo.NewsComments.Ip, 
                      dbo.Roles.RoleName, dbo.Users.UserName, dbo.Users.DateRegistered, dbo.NewsComments.Id, dbo.Users.Avatar
FROM         dbo.NewsComments INNER JOIN
                      dbo.Users ON dbo.NewsComments.UserId = dbo.User,s.Id INNER JOIN
                      dbo.Roles ON dbo.Users.RoleId = dbo.Roles.Id

NewsCommentViews

[Table("NewsCommentViews")]
    public class NewsCommentView : NewsComment
    {
        public string RoleName { get; set; }

        public string UserName { get; set; }

        public DateTime DateRegistered { get; set; }

        public string Avatar { get; set; }
    }
