Thread: configuration settings problem

Code:

using System;
using System.Collections.Generic;
using System.Text;
using System.Configuration;


namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string astring;
            astring = ConfigurationSettings.AppSettings["avalue"];
            Console.WriteLine(astring);
        }
    }
}

Warning 1 'System.Configuration.ConfigurationSettings.AppSet tings' is obsolete: 'This method is obsolete, it has been replaced by System.Configuration!System.Configuration.Configur ationManager.AppSettings' C:\Documents and Settings\mixalis\Local Settings\Application Data\Temporary Projects\ConsoleApplication1\Program.cs 14 23 ConsoleApplication1

In another forum I found :

The most likely issue is that you're missing a reference to the System.Configuration.dll. This particular deprecation was certainly one of the most confusing, because the new type is actually in a completely different assembly. System.Configuration.ConfigurationSettings was in System.dll.

but I cannot understand what I should change!!! Can you help???

xml file
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings>
<add key="avalue" value="mike" />

</appSettings>
</configuration>

Do exactly as you were told:

ConfigurationSettings.AppSettings is obsolete.

Instead, use ConfigurationManager.AppSettings'

To do so, don't forget to include System.Configuration in your references.
