I am preparing an advanced web development course based on ASP.Net. The first question coming to mind (and probably students want to know) is:

Web application frameworks and products built upon ASP.Net

• SharePoint
• DotNetNuke
• ASP.Net MVC
• mojoPortal
• Other smaller ones like: BlogEngine.NET, DasBlog, Gallery Server Pro, nopCommerce

Well, ASP.Net is not just used for websites; it is an enterprise capable technology that is used by many large companies for intranet use and enterprise application development, together with other technologies.
BTW, you can use http://web-sniffer.net/ to see the HTTP header returned from websites. Some of them tell what technology they are based on.
