WebAPI Odata删除动作

Question

我正在尝试使用WebApi 2.2和EF 6.1.2与Code First模型实现Odata端点。我跟着在这里找到教程：

http://www.asp.net/web-api/overview/odata-support-in-aspnet-web-api/odata-v3/creating-an-odata-endpoint

的GET动词的伟大工程，以及为PUT。但是，DELETE请求会返回404错误。有关如何调试此问题的任何建议？

以下是实体，WebApiConfig和Controller的示例。

public partial class BoltLoad 
{ 
    public int Id { get; set; } 

    [StringLength(25)] 
    public string LoadNumber { get; set; } 

    public string BoltUserId { get; set; } 

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

    [StringLength(50)] 
    public string PickupAttention { get; set; } 

    [StringLength(50)] 
    public string PickupLine1 { get; set; } 

    [StringLength(50)] 
    public string PickupCity { get; set; } 

    [StringLength(50)] 
    public string PickupStateProvince { get; set; } 

    [StringLength(50)] 
    public string DropAttention { get; set; } 

    [StringLength(50)] 
    public string DropLine1 { get; set; } 

    [StringLength(50)] 
    public string DropCity { get; set; } 

    [StringLength(50)] 
    public string DropStateProvince { get; set; } 

    public Guid GlobalId { get; set; } 

    [Column(TypeName = "timestamp")] 
    [MaxLength(8)] 
    [Timestamp] 
    public byte[] Version { get; set; } 

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

    [StringLength(256)] 
    public string CreatedBy { get; set; } 

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

    [StringLength(256)] 
    public string ModifiedBy { get; set; } 
} 

public static class WebApiConfig

     db.BoltLoads.Add(boltLoad); 
     db.SaveChanges(); 

     return Created(boltLoad);

     return StatusCode(HttpStatusCode.NoContent); 
    } 

    protected override void Dispose(bool disposing)

     if (disposing) 
     { 
      db.Dispose(); 
     } 
     base.Dispose(disposing); 
    } 

    private bool BoltLoadExists(int key) 
    { 
     return db.BoltLoads.Count(e => e.Id == key) > 0; 
    } 
}

我想出了问题所在。网站设置为以经典模式运行。一旦我将其更改为集成正确执行的DELETE函数。
