ClassFromConfig is a code generation utility that creates wrapper class from your Web.config or App.config.
It generates a C# wrapper class for appSettings and connectionStrings, and it also generates Custom Configuration Sections from your config file. This allows you to quickly prototype sections in XML configuration file and then generate section classes for those sections.
It's a console application written in C#.NET 2.0.
