Error allowDefinition='MachineToApplication' beyond application level in asp.net

Question

recently while working on asp.net application, i got below error:

It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level.  This error can be caused by a virtual directory not being configured as an application in IIS.

i am sure the previous day it was working absolutely fine, however i guess this error occurs usually because of multiple web.config files, but i checked in my project, whole project contains single web.config files, can anyone please tell me what could be the reason for this error.

Answer 1

As the error suggests, You need to set up the directory you've placed the website in as a web application within IIS.

Answer 2
