Solution 1

WFC is a transport layer that allows a web service to communicate with clients.

So the scenario is in this way : i write a webservice.And then i write a wcf to allow people from other sites to use my webservice by giving them access to a certain web method in my webservice.Is that true ?

Not exactly. WCF is a transport layer and can be connected to anything, including a web service. When used together, it's called a WCF web service (or sometimes just a WCF service).

Solution 2

WCF is an 'higher' level programming model compared to Web services.

One example (not the only one) is the transactionality of the WCF: http://msdn.microsoft.com/en-us/library/ms733904.aspx[^]

Not quite. You don't do this separately. Here's one quite good walkthrough: http://www.programminghelp.com/programming/dotnet/wcf-creating-and-implementing-a-service-in-c/[^]

If you only want do create a web service, you don't have to use or learn WFC. For example, it is easy to create a web service that run on IIS and to use that service from a web page.
