Can anybody help?

the sample on page 584 seems not to be right.
I get two errors while trying to use connection strings (i'm using system.configuration!):

The errative line:
  ConnectionStringSettings settings = ConfigurationSettings.ConnectionStrings[name];

The type or namespace name 'ConnectionStringSettings' could not be found (are you missing a using directive or an assembly reference?)

and

'System.Configuration.ConfigurationSettings' does not contain a definition for 'ConnectionStrings'

What is wrong?

I had to add a reference to System.Configuration in the solution explorer.

I've the same problem but adding the reference seems that was not the full solution....any advice?

This problem was fixed in the errata

>The errative line:
> ConnectionStringSettings settings =
> ConfigurationSettings.ConnectionStrings[name];


Replace that with

ConnectionStringSettings settings =
 ConfigurationManager.ConnectionStrings[name];
