Timesheet property not accessible in TimesheetDataSet??!!

[asadim]

How is it that DataTables such as Headers and Actuals which are parts of the
TimesheetDataSet class are accessible as properties but the Timesheet
DataTable is not??

e.g.
WebSvcTimesheet.TimesheetDataSet tds = new
WebSvcTimesheet.TimesheetDataSet();

// tds.Actuals exists
// tds.Timesheets doesn't exist

I used the following to discover that there's actually a Timesheet table
inside the TimesheetDataSet class:

foreach (DataTable t in tds.Tables)
{
Console.WriteLine(t.TableName);
}

Please note that before running the loop I populated tds using the Merge
method. Here's the output:

Headers
Lines
Actuals
CustomFields
Actions
Audits
Timesheets

Thanks for any help.
