Unable to override RabbitMQConnection in AppHost

[lorenzoponsb]

Good morning,

I don't know if it's my fault or a bug, but I can't override the RabbitMQ connectionstring from AppHost:
https://learn.microsoft.com/en-us/dotnet/aspire/messaging/rabbitmq-client-component?tabs=dotnet-cli#use-a-connection-string

I have tried with these two settings in the appsettings.json of AppHost (if I use builder.AddConnectionString("RabbitMQConnection") it works correctly)

My appsettings.json

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning",
      "Aspire.Hosting.Dcp": "Warning"
    }
  },
  "ConnectionStrings": {
    "RabbitMQConnection": "amqp://guest:guest@localhost:5672"
  },
  "Aspire": {
    "RabbitMQ": {
      "Client": {
        "ConnectionString": "amqp://guest:guest@localhost:5672"
      }
    }
  }
}

Can you share the full example? When you call AddConnectionString and you pass it to the WithReference method, it’ll make sure that value has been properly set, or there will be an error the dashboard that explains what to do.

In the apphost the ConnectionStrings section is used

1. AddRabbitMQ - Use this when you want to spin up a rabbit MQ container. Using this method will not read a connection string from configuration.

2. AddConnectionString - This method will read the connection string from the apphost's configuration.

So, is it a documentation bug or a RabbitMQ component bug?

When using a connection string from the ConnectionStrings configuration section, you can provide the name of the connection string when calling builder.AddRabbitMQ

Yes, that looks incorrect.
