Screwed up – Running Asp.Net FW 3.5 app in FW 2.0
I was totally disappointed when found out that my app made in Asp.Net FW 3.5 is not working well when I changed the target framework to 2.0.
This is how it went:
I first started my coding targeting framework 3.5.
One of the Tester asked to make it run on 2.0, I thought “well, with VS 2008 multi targeting feature it would be piece of cake (as I have not used any of 3.5 only libraries)”, but I was wrong.
When I changed the target framework to 2.0, trouble started with AJAX library, it would not automatically change the Ajax dlls in reference to older version. So I have to manually remove all Ajax dll references and added older dlls (which used to work with FW 2.0), now it compiled with targeted framework without error, I thought “great, now I did it”, but again wrong.
When I ran the app under FW 2.0 all of the AJAX support is gone, it behaved like I have not used anything from Ajax toolkit.
I cursed myself and M*t.
