C# 5.0: Asynchronous Programming

For those who are not aware, you can download the Visual Studio Async CTP to get a preview of what is coming in the asynchronous world! This is just the CTP version, so there may be changes between this version and the official release.

Also, visit Eric Lippert’s blog to learn more about the topic.

Reference Documentation

In the November edition of MSDN Magazine, Peter Gruenbaum explains how to write good reference documentation for APIs in his article titled “A Coder’s Guide to Writing API Documentation”.

My attention was particularly drawn to Figures 2 and 3, which explain how to comment while maintaining consistency throughout the API. I have reproduced them here:

Figure 2: Reference Documentation Style

Type Guideline Examples
Class Start with a word like “Represents” “Represents a user’s photo album.”
Methods and functions Start with a verb “Returns the number of contacts for the specified area.”

“Pauses the video.”
Properties Use a noun or start with verbs such as “Gets” or “Gets and sets” “The user’s tasks.”

“Gets and sets a collection of the user’s tasks.”
Events Start with a phrase such as “Raised when” or “Occurs when” “Raised when the response from server is received.”
XML elements Use a noun-based phrase “The city’s postal code.”
Boolean values For Boolean properties, start with “Indicates whether”; for Boolean return values on methods and functions, start with “Returns whether” “Indicates whether the control is visible.”

“Returns whether two regions intersect.”
