Azure Function: Publish fails with message “Web Deploy cannot modify the file on the Destination because it is locked by an external process.”

Question

I am developing an Azure Functions Project and when I publish first time, OK. Then I publish again, this Error appears:

Web Deploy cannot modify the file

Answer 1

Go to the Functions tab in Azure and press the Restart button. Then try to publish again in Visual Studio. Sometimes closing the browser and opening it again or a combination of these things are nessesary.

That is all you need to do.
