Summary

This chapter will introduce the Uniform Resource Identifier (URI). We will describe its purpose, the required parts, and the common components that exist in a URI. This chapter will also introduce System.Uri namespace, the type which used to represent and manipulate a URI in the .NET Framework. Finally we will discuss the issues that developers often encounter when working with System.Uri and exposing it in the application programming interfaces (APIs) that they develop.
