The RegexOptions.ECMAScript flag changes the behavior of .NET regular expressions. One of the changes I had discussed earlier was with respect to matching digits. For those who want to know more, a summary of the differences is documented in MSDN under the devious title “ECMAScript vs. Canonical Matching Behavior”.
Apparently some people had trouble finding that page, so I figured I’d point to it explicitly.
Raymond has been involved in the evolution of Windows for more than 30 years. In 2003, he began a Web site known as The Old New Thing which has grown in popularity far beyond his wildest imagination, a development which still gives him the heebie-jeebies. The Web site spawned a book, coincidentally also titled The Old New Thing (Addison Wesley 2007). He occasionally appears on the Windows Dev Docs Twitter account to tell stories which convey no useful information.
