I was about 30% of the way writing the introduction to SpringFramework.NET for newbies, when it occurred to me "..Surely I'm not the only one on the planet whom thought this would be a good use of my time.."
I then hit Live.com and began to search around and came across this site:
Not only is it a great starting point for SpringFramework, it also offers a consolidated view of what the Framework has on offer. I mention this as with the maturity of MVC Framework coming out, combining SpringFramework with the MVC might not be such a bad idea? (each to their own anyway).
Scope out the above link, assess the framework on whether it suites your own problems and remember that a framework is there to help guide you through a certain type(s) of methodologies that you wish to apply to your code base.
They aren't a rule book, bible or fashion accessory. I mention this as in my experience of the past, I've watched developers use 115 Lines of code to write "hello world" where 2 lines would of be sufficient (all because they bought into the framework trap).
It also plays well with ASP.NET AJAX (Important for me as I'm getting really lazy with my code these days! :D).
