Hi there!
Yes, UWS supports WCF.
In your case, if "c:\www\abcservice" folder contains web.config file and is a root for both service applications, when you need to register just one application with UWS with physical path being "c:\www\abcservice". If "c:\www\abcservice" does not have a web.config and other ASP.NET files, then you need to register two applications with physical paths at "c:\www\abcservice\service1" and "c:\www\abcservice\service2".
