New Post: EF6 auto created Stored Procedures for CRUD

IN EntityFramework 6 documentation page, in "Concurrency Tokens" section says: (link to document)
Concurrency Tokens
•Update and delete stored procedures may also need to deal with concurrency:
•If the entity contains any concurrency tokens, the stored procedure should have an output parameter named RowsAffected that returns the number of rows updated/deleted.

I created EF6 Code First project, and SQL Server 2012 database, stored procedures also created automatically. But UPDATE and DELETE doesn't have any RowsAffected parameter. Why?

But in documentation it's there.

Documentation shows POCO and Update Storage procedure as:

public class Person
{
  public int PersonId { get; set; }
  public string Name { get; set; }
  [Timestamp]
  public byte[] Timestamp { get; set; }
}

CREATE PROCEDURE [dbo].[Person_Update] 
  @PersonId int, 
  @Name nvarchar(max), 
  @Timestamp_Original rowversion, 
  @RowsAffected int OUTPUT      -- ====> !!!!!
AS 
BEGIN
  UPDATE [dbo].[People]
  SET [Name] = @Name   
  WHERE PersonId = @PersonId AND [Timestamp] = @Timestamp_Original   

  SET @RowsAffected = @@RowCount 
END

and EF6 created this for me.

public partial class POCO
{
    //identy
    public int ID { get; set; }

    // SQL Server Timestamp
    // this.Property(t => t.RowVersion).IsFixedLength().HasMaxLength(8).IsRowVersion();
    public byte[] RowVersion { get; set; }

    public int MiscPropery { get; set; }    
}

EntityFramework 6 created insert stored procedure:
CREATE PROCEDURE [dbo].[POCO_Update]
    @ID [int],
    @RowVersion_Original [rowversion],
    @MiscPropery  [int]
    --                  ------- I hope here: @RowsAffected int OUTPUT 

AS
BEGIN
    UPDATE [dbo].[POCOs]
    SET [MiscPropery] = @MiscPropery  
    WHERE (([ID] = @ID) AND (([RowVersion] = @RowVersion_Original) 
            OR ([RowVersion] IS NULL AND @RowVersion_Original IS NULL)))

    SELECT t0.[RowVersion], t0.[FaturaNo]
    FROM [dbo].[POCOs] AS t0
    WHERE @@ROWCOUNT > 0 AND t0.[ID] = @ID
END


EntityFramework 6 created delete stored procedure:
CREATE PROCEDURE [dbo].[POCO_Delete]
    @ID [int],
    @RowVersion_Original [rowversion]
    --                   ------- I hope here: @RowsAffected int OUTPUT 
AS
BEGIN
    DELETE [dbo].[POCOs]
    WHERE (([ID] = @ID) AND (([RowVersion] = @RowVersion_Original) 
          OR ([RowVersion] IS NULL AND @RowVersion_Original IS NULL)))
END

In stored procedures created by EF 6, there is no @RowsAffected parameter. Why?

What is the correct version of strored procedures?
