'MachineToApplication' Error when trying to compile project...

[Guest]

When I'm trying to compile my web application, I get this 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 was recently given this web application to work on it, and when I try to
compile it, that's the first (and only) error I get.

Any help is appreciated.

Make sure that the physical directory in which the files are located in
is configured as an application, or as a virtual directory, in IIS.

Use the IIS Manager to configure it.
