Reason for the article

In dotnet/aspire#5234 (issue) and dotnet/aspire#5223 (PR) we are introducing a new API that allows developers to subscribe to lifecycle events. The idea is that we have an extensible local eventing mechanism to support orchestration. We might use it to trigger an action once a database container is online so we can initialize the database.

Article abstract

The article will need to introduce IDistributedApplicationEventing and how to publish and subscribe to events. It should show how to subscribe to events globally, and how to subscribe to resource-specific events (which can also be subscribed globally).

@mitchdenny is this a release 8.2 request?

[mitchdenny]

No. This work is building up for 9.0

[mitchdenny]

This API will ship in 8.2, but we don't need to go out of our way to document it until 9.0 because its experimental.

I think this should be under AppHost not Fundamentals
