Dnu publish, Process cannot access file
When I publish my dnx web application 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 until someone hits the site and then I can no longer post due to file blocking

I can solve this by RDP'ing to the server and doing iisreset
What is the recommended way to get around this? Post a app_offline.htm
first?

app_offline.htm
dnx is not supported at the moment ( issue # 141 ) and has no effect. - Issue # 141 talks about using WebDeploy to dispose of an application pool . I hate the webdeploy fiddly setup with magic local security policies and hopefully avoid it.
Since this is a UAT box and I might lose my security settings, I added this to my deployment script:
iisreset $targetMachine /restart
where the executor of the script must be the local admin $targetMachine
.
