What is the difference WCF and Web services?

WCF can create services that are similar in concept to ASMX, but it can do much more !!!
WCF is implemented on a different pipeline much more efficient than ASP.Net. It uses different serialization defaults. We can say that under the hood almost everything is different (and better)
WCF has a much better security mechanisms
WCF implement most WS* standards – Asmx Don’t. Thus WCF has security, reliability, transactions, one-way messaging and much more.
With WCF you can use any transport very easily.
As WCF is implemented on a different pipeline it does not have all Http context capabilities (Http session, cache etc)
You can host WCF on any process including a window service. It is very common.
