Should I migrate to ASP.NET MVC?

Question

I just listened to the StackOverflow team\'s 17th podcast, and they talked so highly of ASP.NET MVC that I decided to check it out.

But first, I want to be sure it\'

If you are a professional ASP.NET developer, and have some time to spare on learning new stuff, I would certainly recommend that you spend some time trying out ASP.NET MVC. It may not be the solution to all your problems, and there are lots of projects that may benefit more from a traditional webform implementation, but while trying to figure out MVC you will certainly learn a lot, and it might bring up lots of ideas that you can apply on your job.

One good thing that I noticed while going through many blog posts and video tutorials while trying to develop a MVC pet-project is that most of them follow the current best practices (TDD, IoC, Dependency Injection, and to a lower extent POCO), plus a lot of JQuery to make the experience more interesting for the user, and that is stuff that I can apply on my current webform apps, and that I wasn't exposed in such depth before.

The ASP.NET MVC way of doing things is so different from webforms that it will shake up a bit your mind, and that for a developer is very good!

OTOH for a total beginner to web development I think MVC is definitely a better start because it offers a good design pattern out of the box and is closer to the way that the web really works (HTML is stateless, after all). On MVC you decide on every byte that goes back and forth on the wire (at least while you don't go crazy on html helpers). Once the guy gets that, he or she will be better equipped to move to the "artificial" facilities provided by ASP.NET webforms and server controls.

Answer 2

No, you shouldn't. Feel free to try it out on a new project, but a lot of people familiar with ASP.NET webforms aren't loving it yet, due to having to muck around with raw HTML + lots of different concepts + pretty slim pickings on documentation/tutorials.

I wouldn't recommend just making the switch on an existing project. Perhaps start a small "demo" project that the team can use to experiment with the technology and (if necessary) learn what they need to and demonstrate to management that it is worthwhile to make the switch. In the end, even the dev team might realize they aren't ready or it's not worth it.

Whatever you do, be sure to document it. Perhaps if you use a demo project, write a postmortem for future reference.

If you are dead set on using an MVC framework, then I would rather set out to use Castle project's one...

When that's said I personally think WebControls have a lot of advantages, like for instance being able to create event driven applications which have a stateful client and so on. Most of the arguments against WebControls are constructed because of lack of understanding the WebControl model etc. And not because they actually are truly bad...

MVC is not a Silver Bullet, especially not Microsoft MVC...

I have seen some implementation of MVC framework where for the sake of testability, someone rendered the whole HTML in code. In this case the view is also a testable code. But I said, my friend, putting HTML in code is a maintenance nightmare and he said well I like everything compiled and tested. I didn't argue, but later found that he did put this HTML into resource files and the craziness continued...

Little did he realized that the whole idea of separating View also solved the maintenance part. It outweighs the testability in some applications. We do not need to test the HTML design if we are using WYSWYG tool. WebForms are good for that reason.

I have often seen people abusing postback and viewstate and blaming it on the ASP .NET model.

Remember the best webpages are still the .HTMLs and that's where is the Power of ASP .NET MVC.

I dont´t know ASP.NET MVC, but I am very familiar with MVC pattern. I don´t see another way to build professional applications without MVC. And it has to be MVC model 2, like Spring or Struts. By the way, how you people were building web applications without MVC? When you have a situation that some kind of validation is necessary on every request, as validating if user is authenticated, what is your solution? Some kind of include(validate.aspx) in every page?
