I have heard this going back and forth and wanted a semi-definitive answer. I have been told that extension methods are only valuable on classes you create, since adding it to a base adds it to EVERY base type so an [string ParseString(this string)] would now weight down every string I wrote that referenced the DLL that contained the Extension method. However if you create a class why would you need an extension method you could just call it on the class statically. I have been using extension methods heavily for fluent coding and wanted to know if there is a "best practices".
