I asked a question here on programmers yesterday about learning HTML & CSS and the community was pretty generous to provide great answers. One of the answers was given by Emmad Kareem and that was : "if you can't do HTML, don't give up. Consider using Silverlight".
This answer made me visit Silverlight.net and I came across the terms WCF RIA Services, Silverlight applications. After going through the website and some articles on website i am unable to draw a conclusive understanding on what this is all about.
Is this another way of building websites using .NET, and is just like another framework like ASP.NET MVC3. What scenario's and requirements are basically targeted to silverlight applications or we are free to use either of Asp.net MVC or Silverlight in any web-application requirements.

On Silverlight, Wikipedia tells us (emphasis mine):
And on WCF RIA Services, MSDN tells us (emphasis mine):
Silverlight is an application development platform that's very similar to Adobe Flash and WCF RIA Services is a set of components and a software development toolkit that provides for Silverlight applications to maintain the application logic on both the presentation tier and the middle tier.
The main difference between Silverlight and ASP.Net is that Silverlight applications are vector applications that require a browser plugin to work, whereas the final product of applications built on ASP.Net (what reaches the browser) is a combination of HTML, CSS and JavaScript. Silverlight does not directly compare to ASP.Net MVC, but WCF RIA services might as like ASP.Net MVC is a framework that extends its target platform.
As for the various terms you mention, Silverlight applications are of course applications built on Silverlight, and WCF RIA Services applications or WCF RIA applications are applications built on Silverlight that utilize the extended functionality of WCF RIA Services.
You can watch this interesting video and read this related StackOverflow question to learn more about WCF RIA and you can download the stand alone installer for the WCF RIA toolkit from silverlight.net. By the way, WCF stands for Windows Communication Foundation.
