Vista - WCF using ASP.NET

Dear All,



I managed to create my first WCF application, which is the
HelloWorld. Basically I created the HelloService.cs,
IHelloService.cs, and HelloService.svc, and everything works fine.



However I have an application I am trying to convert from the normal
asmx webservice to WCF.

My idea is to have multiple classes and interfaces in a layer, called
the ServiceLayer, and then 1 svc in another application, calling these
Interfaces, and hosted on IIS.



First of all is it possible to do. And if it is, how can I achieve
that? Does anyone has any examples to show.



Thanks for your help and time



Johann
