For the record, regular expressions in .NET don't have any relation to "the
specifics of the C# and Managed C++ languages" (from this list's name). They're
part of the BCL. Furthermore, "Microsoft .NET Framework regular expressions
incorporate the most popular features of other regular expression
implementations such as those in Perl and awk" and specifically are "Designed
to be compatible with Perl 5 regular expressions", which means most regular
expression documentation applies. But all the same, ".NET Framework regular
expressions include features not yet seen in other implementations, such as
right-to-left matching and on-the-fly compilation" (from the Developer's Guide).

All the same, I've found that using a Regular Expression IDE that lets you
instantly evaluate expressions, and in a sense "debug" them, is usually much
faster for learning than reading the documentation. I've used Expresso[1] on
occasion, but I don't know if there's something better out there.

In my experience, you rarely need to mix String.Replace() and RegEx.Replace();
one well-crafted regular expression usually does the job, and it can make your
code more coherent.
