From the article:

After reading and writing enough code, you begin to notice certain usage patterns. For example, if a stream is open, it will eventually be closed. More interestingly, if a string is used in the context of an if-statement, it will often be to check if the string is empty or if it has a certain size. You begin to identify and use these coding patterns over time, but what if Visual Studio already knew these common patterns and could suggest them to you as you code? That’s exactly what IntelliCode does...
