AzureRmWebAppDeployment fails to stop WebApp and fails with ERROR_FILE_IN_USE

See original GitHub issue

Our Release script uses the “Deploy AzureRM Web App” task and we have set “Take App Offline” to true.

Our WebApp no longer deploys, we get the following errors in the log:

2016-12-22T09:15:40.4470806Z ##[error]Failed to deploy website.
 
2016-12-22T09:15:40.4470806Z ##[error]Error Code: ERROR_FILE_IN_USE
 
2016-12-22T09:15:40.4470806Z More Information: Web Deploy cannot modify the file 'OurWebApp.exe' on the destination because it is locked by an external process.  In order to allow the publish operation to succeed, you may need to either restart your application to release the lock, or use the AppOffline rule handler for .Net applications on your next publish attempt.

2016-12-22T09:15:40.4470806Z Error count: 1.

This used to work a while back, I am not quite sure when this error started happening. If we manually stop the app, the deploy works.

FILE_IN_USE error occurs when DLL’s are locked. App_offline brings the app down and unlocks the resource. ASPCore Module requires app_offline.htm but MSDeploy provides App_Offline.htm (case sensitive).

The fix for app_offline issue will be available soon.
