Dashboard only allows for one level of nested children

[eerhardt]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

With more complex resources, like CosmosDB, ServiceBus, etc., they have 2 levels of child resources.

var cosmos = builder.AddAzureCosmosDB("cosmos")
                .RunAsPreviewEmulator(e => e.WithDataExplorer());

var db = cosmos.AddCosmosDatabase("db");

var entries = db.AddContainer("entries", "/id");

cosmos is the parent of db is the parent of entries.

However, in the dashboard both entries and db show up as direct children of cosmos:

Expected Behavior

We should make entries a child of db.

Steps To Reproduce

Run an AppHost with the above code and view the dashboard.

Exceptions (if any)

Multiple levels are supported:

This is from the stress playground app.

Oh yes there's a bug in cosmos or the parent calculation:

[JamesNK]

The dashboard is doing what the app host is telling it to do, but the app host is giving it bad data.

I think there is a bug in the parent calculation somewhere in here: https://github.com/dotnet/aspire/blob/main/src/Aspire.Hosting/Orchestrator/RelationshipEvaluator.cs

I think we should attempt to fix this in 9.1
