What is a DLL Hell Problem in .Net?

Answer

DLL Hell, is kind of conflict that occured previously, due
to lack of version supportability of dll for(within) an
application.

Previously, if u had deployed any dll for particular
application, and in between u made some changes or provide
some more functionality within that application or u
enhance your application and you deploy new dll or
override existing dll, in this case ur old module which
was/were running fine with previous dll, may behaves
improperly because of new dll deployed.This called dll Hell.

This is no more exist in dot net because of different
version supportability of dll, it means old process worked
with old dll only and respond in exact manner, and new
process which starts after new dll deployed uses(executes
with) new dll and respond to user.
