Describe the bug

Hi, I've tried the Aspire 9.2.1 with Cosmos DB hosting integration with the preview emulator. But the following code does not create databases and containers when we check in the data explorer. I'm wondering if it's a bug or this is not supported yet

var builder = DistributedApplication.CreateBuilder(args);

var cosmos = builder.AddAzureCosmosDB("cosmos-db")
                    .RunAsPreviewEmulator(emulator =>
                     {
                         emulator.WithDataExplorer();
                     });

var customers = cosmos.AddCosmosDatabase("customers");
var profiles = customers.AddContainer("profiles", "/id");

var orders = cosmos.AddCosmosDatabase("orders");
var details = orders.AddContainer("details", "/id");
var history = orders.AddContainer("history", "/id");

builder.Build().Run();

Expected Behavior

I kinda bypass this problem if you add

.WithReference(orders).WaitFor(orders)
.WithReference(details).WaitFor(details)
.WithReference(history).WaitFor(history)

to your projectRefence, but in your exemple you don't seem to have a project ( .AddProject<>)

It's working for me with your sample:

Maybe it's a timing issue, assuming the explorer could start before the containers are actually created. Could you try the refresh icon here:

I have the same problem it's look like a race condition not working 100%, if you try with a microsoft devbox I don't know why but it's easily reproducible. I recommended to try this like 10 times in a row

@kefran06 And refresh doesn't do anything?

[kefran06]

@sebastienros no I tried multiple times the database just do not exist and my app crash with a database container not found. When I look at the RunASEmulator code it's look like a subscription.

my guest is the ReadAccountAsync() is triggered too late or too soon

        {
            if (cosmosClient is null)
            {
                throw new InvalidOperationException("CosmosClient is not initialized.");
            }

            await cosmosClient.ReadAccountAsync().WaitAsync(ct).ConfigureAwait(false);

            foreach (var database in builder.Resource.Databases)
            {
                var db = (await cosmosClient.CreateDatabaseIfNotExistsAsync```

@sebastienros no, the refresh button didn't help here unfortunately
