Hosting a web application using Silverlight 4

9 Feb 2011 by #realJSOP

Hosting a web page (including Silverlight) requires a web server (usually IIS when you're talking about .Net, but Apache can be used as well), even if you're just on a LAN. Clients can't usually change a web site/app so the rest of your question doesn't make any sense.
