如何禁用实体框架来创建Nullable属性

Question

Is there a way to disable or to stop the entity framework from creating Nullable properties in complex class?

Example, when I add a new stored procedure to the entity framework it generates a class like the one below.

    //------------------------------------------------------------------------------
// <auto-generated>
//    This code was generated from a template.
//
//    Manual changes to this file may cause unexpected behavior in your application.
//    Manual changes to this file will be overwritten if the code is regenerated.
// </auto-generated>
//------------------------------------------------------------------------------

namespace StorefrontSystemDL
{
    using System;

    public partial class proc_InsertLeafHorizontal_Result
    {
        public Nullable<int> SizeID { get; set; }
        public Nullable<int> FinishID { get; set; }
        public Nullable<int> SitelineID { get; set; }
    }
}

How can i, do i, or is there a settings that i can set to where the entity framework does not create properties with Nullable types

Below is a snap shot of the source columns.

For my stored procedure here is the body of the tsql

    AS
BEGIN
SET NOCOUNT ON;

 BEGIN TRAN
   BEGIN TRY
EXEC Storefront.proc_InsertHorizontal @Position,@Name,@Floor,@IsFiller,
                                      @WidthInches,@HeightInches,@WidthPercent,@HeightPercent,
                                      @DayliteWidthInches,@DayliteHeightInches,
                                      @Finish,@FinishNote,@FinishType,@FinishName,
                                      @ComponentID,@Note,
                                      @HorizontalID OUT;
    IF(@HorizontalID IS NOT NULL)
     INSERT INTO [StorefrontSystem].[Storefront].[LeafHorizontal]
           ([LeafID]
           ,[HorizontalID])
     VALUES
           (@LeafID,
            @HorizontalID)
----
SELECT h.SizeID,h.FinishID,h.SitelineID FROM Storefront.Horizontal h WHERE h.ID = @HorizontalID;
COMMIT TRAN
END TRY
 BEGIN CATCH
   ROLLBACK TRAN;
 END CATCH
SET NOCOUNT OFF;
END;
