how to use configuration manager in visual studio 2003

[shailesh_007]

Hi All,
I am new in vb.net. I am using Visual Studio 2003 and sql 2000.
I want to use configuration manager to retrive the connection from app.config

But I am getting error " Name 'ConfigurationManager' is not declared"

the code, I written, is as follows:
Imports System.Data.SqlClient
Imports System.Configuration
Imports System.Configuration.ConfigurationSettings
-----------------------------------------------------------------
Namespace PC

Public Class DataEntry
Inherits System.Windows.Forms.Form

Public Shared Function GetConnectionString(ByVal conName As String) As String
Dim strReturn As New String("")
If Not String.IsNullOrEmpty(conName) Then
strReturn = ConfigurationManager.ConnectionString(conName).ConnectionString
Else
strReturn = ConfigurationManager.ConnectionString("Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=ACCOUNTS;Data Source=winxp").ConnectionString

End If
Return strReturn

End Function

Please help me out...

ConfigurationManager did not exist until .net 2.0, use visual studio 2005 to be able to use it.

In .net 1.1 you can use the configuration namespace

System.Configuration.AppSettings

but as stated, in .net 2.0 this is deprecated
