Sandcastle XML Comments Guide

Welcome

Welcome to the Sandcastle XML Comments Guide. This is intended to be a reference that you can use to find out all that you need to know about XML comments as used with Sandcastle to produce help files containing API reference content. If you have any information, tips, updates, or corrections that you would like to see added to the guide, feel free to submit them to the author using the Send Feedback link at the top of the page or the e-mail link in the page footer.

Conventions

The XML comment elements are separated into four categories:

  • Section - These elements are used to define the content for the different sections of the documentation of a type or member and are always top-level elements that appear at the root of the XML comments block. Examples are summary and remarks.

  • Block - These elements format text within the top-level section elements. They are typically used to add structure to the text inside those elements. Examples are code and list.

  • Inline - These elements are typically used inside the other section and block elements to provide formatting such as the c element or links to other API topics such as the see element.

  • Miscellaneous - These elements are typically top-level or mixed use elements that do not fit one of the other categories such as include and inheritdoc.

For each XML comments element, information will be given about its placement and usage along with one or more examples. In the syntax examples, optional attributes and parameters will be enclosed in square brackets ([ ]). If an attribute allows you to specify a value from a defined list of values, those values will be shown separated by a pipe character (|). The See Also section will contain links to example API members so that you can see how a topic containing the element is rendered in an actual help file.

Certain elements or attributes they utilize are implemented by Sandcastle or are only usable with a particular third-party tool such as the Sandcastle Help File Builder. Such extensions to the standard XML comments elements and attributes will be noted in the affected topics.

Since the syntax of the XML comments themselves are language neutral with the exception of the comment characters that precede them, all example code is shown only in C# to reduce unnecessary clutter. Substitute your language's XML comments characters (i.e. triple apostrophe (''') for VB) and the XML comments will work the same way.
