There's a wide gap between where ASP.NET's usefulness ends and where the really fancy stuff begins.
And yes, you totally can beat the libraries available on the "Dark Side." You'd have to try hard not to.
It all boils down to what you are doing. Lots of shops can have 3 or 4 coders doing the mainline stuff and 1 guy who can do the tricky stuff. It's an effective use of lower-skilled programming resources.
I'd have to disagree with you on the libraries. While I'm sure there are some good libraries out there, when I'm plugged into VS I've got some kazillion or so things I can do without having to Google, link, recompile, or do squat. And I can easily make libraries to share with others. It depends on your needs. Since MS does a little bit of everything for everybody, the libraries are probably the broadest that are easily available.
Hey! How did you find out about my startup idea?
Of course, you're free to use a chicken.
Also things that rhyme with "slink"
Oh come on, this applies for ANY tool in ANY domain. This is non-information.
Take two programmers who are novices. Throw them into any two languages. If we use an automated DAL and a mentor-apprentice training paradigm in both languages, I can have the ASP.NET guy up and running and more productive faster than the other guy. <disclaim>for writing average run-of-the-mill web apps</disclaim>
That is my stupid way of saying, who gives a crap how long stupid ASP.NET guy takes to get productive? In the long run, inevitably, someone else will be better.
I liked it better with the forumlas. (grin) Seriously -- that's a good point. But I don't think it is language-dependent. Might be. I don't know. From what I've seen languages and platforms are just new and interesting ways for programmers to shoot themselves in the foot. Good programming remains the same now as it was decades ago. That is, unless somebody has started using the force and I don't know about it.
The problem isn't ASP.NET: it's probably the way you were taught how to use it. The Microsoft tools do so much crap that it's like being put into a room full of levers and knobs with cryptic labels on them. Hard to know where to start or how to make things work.
Sit down with somebody who is using one of the automated DALs (like NetTiers, NHibernate, CSLA, etc) and knows what the heck they are doing. You'll find it very intuitive and the speed of development can keep pace (or surpass, depending on the domain) any other kind of web development.
Now for the BUT part. BUT you have to be doing straight-forward business development. Stuff in the middle of the road. Writing a check. Checking your email. Posting a message.Viewing your box scores. Etc. If you want something like an animated dancing baby that does different dances depending on your current stock portfolio and can sing out your RSS feeds in different languages, you're back to basics, and all that abstraction is going to get in your way big time. Also, if you want to scale up to 100K users quickly you're going to be learning a lot more about tweaking IIS and ASP.NET than you probably wanted. But for a lot of stuff, it's just fine. Not everybody is writing the next YouTube, and you can't beat the libraries available to you over on the "dark" side.(grin)
