Webdeploy from commandline not taking app offline even with -enableRule:AppOffline

When I try to run this command from commandline to deploy asp.net core website:

"C:\\Program Files\\IIS\\Microsoft Web Deploy V3\\msdeploy.exe" -allowUntrusted -verb:sync -sourc
e:contentPath="%USERPROFILE%\ProjectFolder\bin\release\netcoreapp1.1\publish" -dest:contentPath="sitename",ComputerNa
me="https://siteurl.com:8172/msdeploy.axd?site=sitename",UserName='myusername',Password='mypassword',AuthType='Basic' -enableRule:AppOffline -retryAttempts:20

Get this error:

Error Code: ERROR_FILE_IN_USE

When I stop website on web server, then deployment succeeds:

I was expecting -enableRule:AppOffline should force website offline. But it still keeps the lock on website dll.

How we can force webdeploy to overwrite files?

Try increasing -retryInterval and/or -retryAttempts parameters:

Wow. This issue was a bear for me. I could not get -enableRule:AppOffline on my actual deployment command. Nor could I get this to work in my pubxml file:

<PropertyGroup>
    <EnableMSDeployAppOffline>true</EnableMSDeployAppOffline>
</PropertyGroup>

(I'm using IIS v10)

This Microsoft blog post indicates that either will work, but no dice for me!

Anyway, these 2 references helped me a lot:

  1. https://github.com/aspnet/AspNetCoreModule/issues/50#issuecomment-268820798
  2. https://learn.microsoft.com/en-us/iis/publish/deploying-application-packages/taking-an-application-offline-before-publishing

The real trick was in the second reference, the tile says "before Publishing". So you need to actually run msdeploy.exe separately before your main deploy.

Here is the PowerShell code I used:

# Deploy app_offline.htm
$IisApp = Get-IisAppName
$AppOfflineFilePath = "`"C:\path with spaces\app_offline.htm`""

Log-Begin "Deploy app_offline.htm"
& $MsDeployPath -verb:sync -source:contentPath=$AppOfflineFilePath -dest:contentPath=$IisApp/app_offline.htm,ComputerName=$ServerName,UserName=$UserName,Password=$Password,IncludeAcls="False"
Log-End "Deploy app_offline.htm" $LastExitCode

Write-Host "Sleeping for 4 seconds to give the app_offline.htm a chance to take effect."
Write-Host "If you get a locked DLL error, just try the deployment again!"
Start-Sleep -Seconds 4

# Within the ZIP file is a MS Web Deploy Package ZIP, a cmd (to run the deploy), and some other files.
$DeployCommandFilePath = Get-ChildItem $pwd *.deploy.cmd -Recurse | Where-Object {$_.FullName.length -lt 260} | Select-Object -First 1 | Resolve-Path -Relative

Log-Begin "deploy.cmd"
& $DeployCommandFilePath /Y /M:$ServerName /U:$UserName /P:$Password
Log-End "deploy.cmd" $LastExitCode

Note that I added a short sleep to allow the app_offline.htm file a chance to take effect. It is not immediate.

I have IIS set up to automatically delete the app_offline.htm file on a deploy, so I did not need this, but here is the code if you need it:

# Delete app_offline.htm
Log-Begin "Delete app_offline.htm"
& $MsDeployPath -verb:delete -dest:contentPath=$IisApp/app_offline.htm,ComputerName=$ServerName,UserName=$UserName,Password=$Password,IncludeAcls="False"
Log-End "Delete app_offline.htm" $LastExitCode

Can you see on the site if the App_Offline.htm is being created? If yes, try renaming to app_offline.htm (all lower case). Does that shutdowns the site? There is bug in AspNetCoreModule for App_Offline.htm file being case-sensitive, see here.
