This post shows an example of a small application that hosts WCF services and html-pages with a Silverlight application. This application is the simple web-server, in fact, so we do not need IIS at all.
The presented source code can be used as a template for similar projects. Just compile the solution in Visual Studio (VS) and start it as Administrator, then type http://[computername]:8080 in your browser. You can also access to this application from remote computers (please do not forget about the firewall).
