Linq-To-Sql SP will not be mapped to a class

I have a class in my Linq-To-Sql model and am trying to map a stored procedure to it. No matter what I try, I get a message:

one or more selected database objects return a schema that does not match

The scheme definitely matches, I even resorted to a simple "select top 100 rows" auto-generation in SSMS and putting this in SP, nothing more, and I still get this message.

Is there anything else I should look at?

My table layout is as follows:

CREATE TABLE [dbo].[Booking](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [ClientID] [int] NULL,
    [BookingTypeID] [int] NULL,
    [LinkedBookingID] [int] NULL,
    [DateCreated] [smalldatetime] NULL,
    [DateUpdated] [smalldatetime] NULL,
    [BookingDateTime] [smalldatetime] NULL,
    [BookingStatusID] [int] NULL,
    [ConfirmationRequired] [bit] NOT NULL,
    [Confirmed] [bit] NOT NULL,
    [InProgress] [bit] NOT NULL,
    [ServiceID] [int] NULL,
    [EmployeeID] [int] NULL,
    [Duration] [int] NULL,
    [ProcessingDuration] [int] NULL,
    [IsPartOfCourse] [bit] NULL,
    [CancellationReason] [int] NULL,
    [Timestamp] [timestamp] NULL,
    [IsLinked] [bit] NULL,
 CONSTRAINT [PK_Booking] PRIMARY KEY CLUSTERED 
(
    [ID] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON, FILLFACTOR = 90) ON [PRIMARY]
) ON [PRIMARY]

and SP:

CREATE PROCEDURE booking_test


AS
BEGIN


SELECT TOP 1000 [ID]
      ,[ClientID]
      ,[BookingTypeID]
      ,[LinkedBookingID]
      ,[DateCreated]
      ,[DateUpdated]
      ,[BookingDateTime]
      ,[BookingStatusID]
      ,[ConfirmationRequired]
      ,[Confirmed]
      ,[InProgress]
      ,[ServiceID]
      ,[EmployeeID]
      ,[Duration]
      ,[ProcessingDuration]
      ,[IsPartOfCourse]
      ,[CancellationReason]
      ,[Timestamp]

  FROM [Booking]

END
