We are getting some unexpected and undesirable behavior from iis:WebAppPool and
iis:WebSite extensions, just checking to see if we are doing something wrong.
background
Specifically we have the following relevant snippet of wix that defines our
appPool setting and the WebSite we want created to use it. Everything works
as expected when installing against a box where none of this is present. We
do not remove the appPool and the WebSite on uninstall because we don't want
ops to have to redo ssl binding certificate associates and other environment
specific stuff after each uninstall / reinstall of a new build.
What we are finding is installing against a host where the appPool and website
is already in place appears to reapply the appPool setting. Specifically if
some non-deliverable specific vdir application has been manually created under
the website and granted an appPool setting other than our deliverable specific
appPool then when we reinstall that vdir application ends up getting its
appPool changed. Similarly if ops has changed the appPool we provisioned on
first installer pass to use a different identity when we reinstall it gets set
back to the identity defined in our wix.
question
is this behavior expected and is there any way we can leave appPool and website
in place after first install attempt and not have an custom tweaks made by ops
reverted during subsequent installer passes?
