Question

我在我的一个项目中使用EF 6.1.3，最近我遇到了一个有趣的错误。当我在选择查询中使用下面的Investigation类时，它会抛出下面附带的错误。

一旦我替换服务器上的Entity Framework特定dll，错误就会得到解决。但我不能做这个制作。任何人都可以帮助我理解有关此错误的任何信息，看看如何解决它？

表定义：

    CREATE TABLE [dbo].[Investigation](
    [Id] [int] IDENTITY(1,1) NOT NULL,
    [StatusId] [int] NOT NULL,
    [CreatedOn] [datetime2](7) NOT NULL CONSTRAINT [DF_Investigation_CreatedOn]  DEFAULT (getdate()),
    [AssignedOn] [datetime2](7) NULL,
    [DueBy] [datetime2](7) NULL,
    [LastModified] [datetime2](7) NOT NULL,
    [LastModifiedBy] [uniqueidentifier] NOT NULL,
    [IsSent] [bit] NOT NULL,
 CONSTRAINT [PK_Investigation] 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]

Model类是

public partial class Investigation
    {
        [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2214:DoNotCallOverridableMethodsInConstructors")]
        public Investigation()
        {
            InvestigationHistories = new HashSet<InvestigationHistory>();
            Investigators = new HashSet<Investigator>();
            SubTopicInvestigationAssocs = new HashSet<SubTopicInvestigationAssoc>();
        }

        public int Id { get; set; }

        public int StatusId { get; set; }

        [Column(TypeName = "datetime2")]
        public DateTime CreatedOn { get; set; }

        [Column(TypeName = "datetime2")]
        public DateTime? AssignedOn { get; set; }

        [Column(TypeName = "datetime2")]
        public DateTime? DueBy { get; set; }

        [Column(TypeName = "datetime2")]
        public DateTime LastModified { get; set; }

        public Guid LastModifiedBy { get; set; }

        public bool IsSent { get; set; }

        [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
        public virtual ICollection<InvestigationHistory> InvestigationHistories { get; set; }

        [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
        public virtual ICollection<Investigator> Investigators { get; set; }

        [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
        public virtual ICollection<SubTopicInvestigationAssoc> SubTopicInvestigationAssocs { get; set; }
    }
