Why EXCEL wont Close after use in vb.net

xls will not stop/end after use in vb.net
       
 
 
 I have asked this question before but still no answers.

I have an application (vb.net 2005) that use the following I then need to delete after it is finished doing what I am doing.. but I keep getting an error that it is still in use. and when I look at task manager processes there is still an excel app running, even though it is not in the current tasks.

PLEASE HELP HOW DO I REMOVE THE EXCEL FROM THE PROCESS!!!!!!!!!!!!

Imports VBIDE = Microsoft.Vbe.Interop

Imports Microsoft.Office.Core

Dim xlsApp As Excel.Application

Dim xlsWB As Excel.Workbook

Dim xlsSheet As Excel.Worksheet

Dim xlsCell As Excel.Range

xlsApp = New Excel.Application

xlsWB = xlsApp.Workbooks.Open(c:test.xls)

xlsSheet = xlsWB.Worksheets(1)

xlsCell = xlsSheet.Range("A1")

xlsWB.Close()

xlsApp.Quit()

System.Runtime.InteropServices.Marshal.ReleaseComObject(xlsSheet)

System.Runtime.InteropServices.Marshal.ReleaseComObject(xlsWB)

System.Runtime.InteropServices.Marshal.ReleaseComObject(xlsApp)

xlsWB = Nothing

xlsApp = Nothing

xlsSheet = Nothing
