When I upgraded my VB6 code to VB.NET I got this error.

'UPGRADE_NOTE: Object FSO may not be destroyed until it is garbage collected. Click for more: 'ms-help://MS.VSCC.2003/commoner/redir/redirect.htm?keyword="vbup1029"'
FSO = Nothing
'UPGRADE_NOTE: Object FileName may not be destroyed until it is garbage collected. Click for more: 'ms-help://MS.VSCC.2003/commoner/redir/redirect.htm?keyword="vbup1029"'
FileName = Nothing
'UPGRADE_NOTE: Object TS may not be destroyed until it is garbage collected. Click for more: 'ms-help://MS.VSCC.2003/commoner/redir/redirect.htm?keyword="vbup1029"'
TS = Nothing

How do I make sure that i am destroying these objects or what is the correct way to do this in VB.NET. Thanks in advance.
