How I Can Generate XML Documentation File of My .Net Application?

Here I will describe two easy way for generating documentation file in .net application:

Way One: (From Visual Studio)
The Generate XML documentation file property determines whether an XML documentation file will be generated during compilation. To set this property in visual studio follow following steps:

• With a project selected in solution explorer, on the project menu, click properties.
• Click Build tab.
• Select XML Documentation File.

You can optionally specify output path.

Way Two: (Using GhostDoc)
GhostDoc is a Visual Studio extension that automatically generates XML documentation comments for methods and properties based on their type, parameters, name, and other contextual information.
