What breaks

After 14 Nov 2028, apps that use .NET 10 continue to run unchanged, but App Service can't provide security patches or related customer support for that runtime version.

An app on an unsupported language version must be upgraded to a supported version before it can get App Service support.
App Service sends reminder notifications about end-of-support dates to subscription owners.
Contributors, readers, or other roles don't directly receive notifications unless they opt in through Service Health Alerts.
For Java, the page adds that developers who use a supported Java runtime that is retired receive a deprecation notice at least six months before the runtime is retired.
