Silverlight replacing ASP.NET?

[chris128]

OK so im going to need to (at some point) create a web front end for my current project. Currently the only presentation layer I will have is a WPF desktop application but I will need something web based as well fairly soon so I'm considering the relevant options.
I assumed I would have to learn ASP.NET (something im not very keen on doing after my encounters with ASP.NET so far have left me frustrated and confused) but then it occurred to me that Silverlight could be an alternative, and a much prettier one at that.

So, having never used Silverlight before, I just wondered if anyone had any comments on how suitable it is for a business application (as opposed to just making a nice looking website, which is all ive seen it used for so far) that needs to work with databases and class libraries etc?

EDIT: Found this silverlight application which makes me think line of business apps in silverlight are very much possible: http://weblogs.asp.net/blogs/lduveau...b2ba5bd58e.png
