Getting all logs requires the ResourceLoggerService…

Error message

Getting all logs requires the ResourceLoggerService instance created by DI.

What it means

The IConsoleLogsService resolved outside DI is a FakeConsoleLogsService placeholder whose GetAllLogsAsync always throws. Real log retrieval requires the ResourceLoggerService instance registered in the dependency injection container.

Solutions

Resolve IConsoleLogsService from the Aspire host's DI container
Use ResourceLoggerService directly when operating outside the host lifecycle
In tests, register a real or fake ResourceLoggerService-backed implementation in the test DI container

Example fix

// before
var logsService = new FakeConsoleLogsService(); // throws on use
// after
var logsService = serviceProvider.GetRequiredService<IConsoleLogsService>();

Defensive patterns

Strategy: try-catch

Try / catch

try { await logsService.GetAllLogsAsync(name, ct); }
catch (InvalidOperationException ex) when (ex.Message.Contains("created by DI")) { /* resolve the service from the host DI container instead */ }

Prevention

Always obtain IConsoleLogsService via dependency injection
Never construct log service placeholders manually in production code

When it happens

Trigger: Calling GetAllLogsAsync on an IConsoleLogsService obtained without DI — e.g., manually constructing the service or resolving it from an empty/non-Aspire service provider.

Common situations: Unit tests or tools instantiating log services by hand; retrieving console logs before the AppHost's DI container is built.
