webapp:Support AppOffline With Publish-AzureWebsiteProject #669
Description
Occasionally when publishing to an Azure Web App from Visual Studio Online an error similar to the following occurs:
Web Deploy cannot modify the file '{FILENAME}' 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.

The Publish-AzureWebsiteProject cmdlet should support a parameter with allows the AppOffline rule to be used, or indeed a way to pass arbitrary additional flags on to MSDeploy.
