I can't imagine what is causing this. My site is running DNN 4.8 with asp.net 3.5 and as you can see it runs fine:

http://dnnsilverlight.adefwebserver.com/

I think you may have a module that is causing incompatibilities. Perhaps a compression module or some other assembly? Can you install a fresh copy of DNN and set it to use asp.net 3.5 and see if you get the same behavior?

It seems i was happy too early.

it returned back.

i made clean install  of new dnn site , convert it to 3.5 target platform (in the properties of the Dotnetnuke_2 website),

and it compiled fast.

after i just upload my custom module ( which is the store module i'm extending ...) again the compilation time of first time accessing the first page of dnn

took VERY LONG.

the same when clicking on the LOGIN link - vbc.exe is taking 50% and compiling about 1-2 MINUTES until showing the login control.

after that trying to access other pages of the site are fairly good.

the next time i'm accessing the site - it goes smoothly.

but every change i made in the code which requires new compilation - and the whole process happening again.

is there a setting in web.config which i can change to work better with dnn and .net 3.5?

why is not happening with .net 2.0?

how can i check it with a tool of vs 2008 team system? - i'm not familiar with all the tools of vs 2008 team system

Its the Store module - i don't see somthing not compatible with .net 3.5.

any idea?

thanks

what is the difference?

I red somewhere that a good practice is to copy the source version on top of an older version for upgrade.

anyway, it seems to be a known issue with vs2008

but the solution there didn't work for me (as for the others there) - its a problem with large web app i guess.

i use vista x64 ultimate, dnn 4.8.2 ,sql express 2005.

does anyone else got this behavior with dnn? any idea? solution ?   new hotfix ?

( i installed

Microsoft Visual Studio 2008
Version 9.0.21022.8 RTM
Microsoft .NET Framework
Version 3.5
