Public Function GetTIMESHEETsMonday() As Double

        Dim Monday As Date = GetThisMondayDate()

        Dim totalTime = From t In Me.ObjectContext.TIMESHEETs
                            Where t.TaskDate = Monday
                            Select t

        If totalTime.Count <> 0 Then
            Return Aggregate T In totalTime Into Sum(T.TaskTime)
        Else
            Return 0
        End If

    End Function

Dim sum As Integer = IIf(query IsNot Nothing, query.Sum(), 0)
