App Service upgrades the underlying .NET runtime and SDK of your application as part of the regular platform updates. As a result of this update, your application will be automatically updated to the latest patch version available in the platform for the configured minor version of your app.
Once a version of .NET has reached it's end of life (EOL) it will no longer be available from Runtime Stack selection dropdown.
Existing applications configured to target a runtime version that has reached EOL should not be affected.
During the early access period, apps will be subject to the Early Access limitations listed in the early access support document.
App Service updates existing stacks after they become available from each community. Please reffer to the official .NET Support timeline for the most up to date version support information.
You can find the list of supported versions using the list-runtimes command from the Azure CLI. az webapp list-runtimes will list all the versions that are currently supported (not EOL) for a given runtime.
# Available runtimes on Linux
az webapp list-runtimes --os-type linux
# Available runtimes on Windows
az webapp list-runtimes --os-type windows
NOTE: Changing the stack settings of your app will trigger a re-start of your application.
