I found ASP.NET MVC Preview 3 just released, Because of my great passion in .Net, I can't wait any longer to upgrade CTSpace to the newest version.
I downloaded the setup file, installed it，and copied the three .dll files to the web project into bin folder, and updated the Global.asax file and the web.config file, modified the controller just as the readme document described，after these I pressed F5 key... image that everything would happen just as what I thought. But there was an exception page displayed.
In the next 2 hours I visited the ScottGu's Blog introducting MVC Preview 3, and read the every word in the readme file again, after tested many many times, at last I got the reason, I made a low-lever mistake.
……
After deployed the new programm, suddently I felt the whole morning was gone, and I planed many stuff to do this day.
That's me, lack of time-awareness, and always fool myself with many reasons, such as 'follow my passion'.
