c# - Migrating asp.net from 32 bit to 64 bit webform application -


i have asp webform application build in 3.5 , runs on 32bit server. have migrated 4.5.1 working fine have got new server 64bit , want update application run on 64bit because got oom exception last days.

when build configuration set 64 cpu, system.badimageformatexception. under additional information, says not load file or assembly dll_name,..... attempt made load program incorrect format.

i too:

signtool error no certificates found met given criteria

but have valid certicate 2018.

i guess problem use external library (due badimageformatexception exception), isn't platform-independent. 1 have experience oracle.dataaccess. comes in 2 flavors: 32-bit , 64-bit version of library.

make sure application doesn't use external libraries require run on 32-bits , replace them 64-bit counterparts.
