The C# compiler reads documentation comments in your code and formats them as XML into a file whose name you specify in the /doc command line option. To create the final documentation based on the compiler-generated file, you can create a custom tool, or use a tool such as Sandcastle.

Tags are processed on code constructs such as types and type members.

Note:
Documentation comments cannot be applied to a namespace.

The compiler will process any tag that is valid XML. The following tags provide generally used functionality in user documentation.
