AddAzureCosmosDB is not working with AddCosmosDbContext

[mwiedemeyer]

Is there an existing issue for this?

Describe the bug

I have a very simple demo app here: https://github.com/mwiedemeyer/AspireDemo
Updated to Aspire 9.1

In the AppHost I add a CosmosDB resource with

var cosmos = builder.AddAzureCosmosDB("cosmos")
                    .RunAsPreviewEmulator(p => p.WithDataExplorer().WithDataVolume().WithLifetime(ContainerLifetime.Persistent))
                    .AddCosmosDatabase("db")
                    .AddContainer("users", "/id");

In my client a try to add a cosmos EF context with:

builder.AddCosmosDbContext<AppDbContext>("cosmos", "db");

However it fails, because it cannot find the connection string.

In the env variables of my client it shows only these connection strings mapping to the cosmos db:

• Aspire__Microsoft__Azure__Cosmos__users__ConnectionString
• users

The client fails with this error message:

'A DbContext could not be configured. Ensure valid connection information was provided in 'ConnectionStrings:cosmos' or either ConnectionString or AccountEndpoint must be provided in the 'Aspire:Microsoft:EntityFrameworkCore:Cosmos' or 'Aspire:Microsoft:EntityFrameworkCore:Cosmos:AppDbContext' configuration section.'

So the names do not match. Is there anything I need to do to fix it?
I also tried this one, but it fails either:

builder.AddCosmosDbContext<AppDbContext>("users", "db");

Expected Behavior

I expect the documented version to work like in the description above

Steps To Reproduce

Run the demo project from here https://github.com/mwiedemeyer/AspireDemo
Then open the console logs for the func and click on the link (something like http://localhost:7184/api/Function1)

Exceptions (if any)

InvalidOperationException

'A DbContext could not be configured. Ensure valid connection information was provided in 'ConnectionStrings:cosmos' or either ConnectionString or AccountEndpoint must be provided in the 'Aspire:Microsoft:EntityFrameworkCore:Cosmos' or 'Aspire:Microsoft:EntityFrameworkCore:Cosmos:AppDbContext' configuration section.'
