VB.Net - The provider is not compatible with the version of oracle client

Hi again.

I'm facing an issue where i'm trying to connect to Oracle Home client 11g 32 bits.

I'm getting below error:

the provider is not compatible with the version of oracle client

I took from from the new Install Oracle folder ODP.NET / BIN / 2x the Oracle.DataAccess.dll
Then, i pasted in the folder bin\Debug\net5.0-windows, where the exe his situated.

Then i added the reference inside the project as below




After all this, i'm getting the error: The provider is not compatible with the version of oracle client


The error i have is on:

cmd As New OracleCommand(sql)

Select allOpen in new window

The code i have is below;

Private Sub Button4_Click(sender As Object, e As EventArgs) Handles Button4.Click
 
        Dim oradb As String = "Data Source=datasource;User Id=user;Password=password;"
        Dim conn As New OracleConnection(oradb)
        Dim connect As Object = Nothing

        Try
            conn.Open()
            ' connect.Enabled = False


            Dim sql As String = "Select name from client'"

            Dim cmd As New OracleCommand(sql)
            cmd.CommandType = CommandType.Text

            Dim dr As OracleDataReader = cmd.ExecuteReader()
            dr.Read()

            departments.Items.Add(dr.GetString(0))

        Catch ex As Exception

        End Try
    End Sub
End Class

Select allOpen in new window

What do i need to look at to fix the problem?

I'm pretty new to Visual Studio 2019.

Thanks for your help.
