How to replace obsolete class?

For insert records in Featureclass I use:

Using comReleaser As ESRI.ArcGIS.ADF.ComReleaser = New ESRI.ArcGIS.ADF.ComReleaser()
comReleaser.ManageLifetime(featureBuffer)
comReleaser.ManageLifetime(insertCursor)

I get the Warning : 'ESRI.ArcGIS.ADF.ComReleaser' is obsolete: 'The assembly containing this class is obsolete. Reference the ESRI.ArcGIS.ADF.Connection.Local assembly instead.'.

How to replace obsolete class ESRI.ArcGIS.ADF.ComRelease?
Example, please.
