更新: 6月 18, 2018
Starting June 30, all new apps in Azure App Service will be created with TLS 1.2 by default.
Although we don't recommend it, you can select TLS 1.1 or 1.0. The update can take place through the Azure portal and Azure CLI. For details on how to make your selection, see the documentation.
