Could anyone can tell me where I can find full ASP.NET MVC beta documentation?
http://www.asp.net/mvc/ would be the most logical place to start looking.
A few good places to start:
I would expect full documentation to be more available at release time.
MVC is also open source and is on CodePlex, so you can just look through the source of course.
Project is here: http://www.codeplex.com/aspnet and here: http://www.codeplex.com/MVCContrib
Documentation is here: http://www.codeplex.com/MVCContrib/Wiki/View.aspx?title=Documentation&referringTitle=Home
There is a book coming out through Manning press. It's not published yet but you can download the juicy stuff through their early access program. If you want a lot of info in one place it might be a good bet.
You can find it on MSDN site here ASP.NET Model View Controller (MVC)
