Configuration Namespaces in Visual Studio
The configuration namespaces in the .NET Framework include:
System.Configuration - contains classes that are used to programmatically access .NET Framework configuration settings and handle errors in configuration files.
System.Configuration.Assemblies - contains classes that are used to configure an assembly.
System.Configuration.Install - provides classes that allow you to write custom installers for your own components.
System.Configuration.Provider - contains the base classes shared by both server and client applications to support a pluggable model to easily add or remove functionality.
