In the Code Editor, position your cursor on the line above the type or member for which you want to create documentation.

Type ''' (three single-quotation marks).

An XML skeleton for the type or member is added in the Code Editor.

Add descriptive information between the appropriate tags.

Note:
If you add additional lines within the XML documentation block, each line must begin with '''.

Add additional code that uses the type or member with the new XML documentation comments.

IntelliSense displays the text from the <summary> tag for the type or member.

Compile the code to generate an XML file containing the documentation comments. For more information, see /doc.
