Answer 1

I was getting the same error while I was trying to publish my Azure Function App. I followed this Microsoft document and did the following steps.

1. Right click on your Project and select Edit ....csproj

2. Add true in PropertyGroup tag

   
     netcoreapp2.1
     v2
     true
   
   

3. Save and Rebuild your solution

4. Now publish again

If that didn't work for you, you can always add MSDEPLOY_RENAME_LOCKED_FILES=1 as Mr. Ben mentioned in his answer, to your Application settings. You can do that from Visual Studio itself.

Hope it helps
