Configure point-to-site VPN from Function to VNet
Functions are great. VNets are great. Point-to-site VPN is great. It would be even greater, if you could configure a function app to talk securely with a VNet through point-to-site VPN. Just as you can with a web app.

This would for sure remove one of the blockers that exist for moving from Azure Cloud Services to Azure Functions.
