Switching to ADO.net

[Genom]

My first db application works with this code to run SQL commands:

Dim RS As New ADODB.Recordset
    Dim DS As New DataSet
    Dim OL As New OleDb.OleDbDataAdapter
'........ Other codes...
    Private Function GetInfo() As Boolean
        On Error GoTo Err
 
        DS.Tables.Add(TableCostumers)
        OL.Fill(DS.Tables(TableCostumers), RS)
        DS.DataSetName = CN.ConnectionString
        DGW.DataSource = DS.Tables(TableCostumers)
 
 
        Return True
        Exit Function
 
Err:
        MsgBox("...", MsgBoxStyle.Critical, AppTitle)
        Return False
 
    End Function

Now I want to change it to ADO.Net without big changes. Idea is that my applciation generates SQL commands and gets info like the code in this post. I don't want to make big changes. Actually I only want to eliminate recordset, because I dont want that anything stay from ADODB...
How can I do that?
