Extending Metadata Using Attributes

The common language runtime allows you to add keyword-like descriptive declarations, called attributes, to annotate programming elements such as types, fields, methods, and properties. Attributes are saved with the metadata of a Microsoft .NET Framework file and can be used to describe your code to the runtime or to affect application behavior at run time. While the .NET Framework supplies many useful attributes, you can also design and deploy your own.
