Allow for Empty Default Landing Page in Azure Function App Deployments
You can see a detailed explanation as to why this is a necessary feature here: https://github.com/Azure/Azure-Functions/issues/1439.
It is possible to create an empty default landing page using the azurewebjobsdisablehomepage app setting.
