Often application need custom configuration section. System.Configuration namespace includes classes for reading and writing configuration settings.
There is a slight difference in how you use this namespace depending on the Framework version you are using
Prior to .Net Framework 2.0, the .Net Framework included System.Configuration namespace, but that version of the namespace is now outdated. If you simply add the System.configuration namespace to your project (using in C#), your application references the outdated namespace.
To refer to the updated namespace, follow these steps
1. In VS, open the project that requires System.Configuration namespace.
2. Click on the Project menu and then click Add Reference
3. On the .Net tab, Select System.Configuration as shown in following figure, and click OK
4. Now add the System.Configuration namespace to your project normally using Imports (in VB) or using (in C#) and your application will reference the correct version of the namespace.
