dnu publish, The process cannot access the file

When I publish my dnx web app via dnu publish to an IIS server, it works fine with a script that looks like this

dnu publish pathToLocalSource --out \\appserver\appuat --configuration DEBUG --no-source --runtime dnx-clr-win-x64.1.0.0-beta6

It works fine that is - until someone hits the website and then I can no longer publish due to a file lock

I can solve this by RDP'ing to the server and executing iisreset

What is the recommended way to get around this? Publish an app_offline.htm first?

So since this is a UAT box and I can be loose with security settings, I added this to my deploy script:

iisreset $targetMachine /restart

where the executor of the script needs to be a local admin of $targetMachine.
