It would be good to try to re-enable some of these tests, to prevent situations like https://github.com/dotnet/aspire/issues/5898.

This issue title just says TestServicesWithMultipleReplicas, but there are 19 tests in DistributedApplicationTests that are CI disabled and pointing to this issue.

I'm currently facing this issues in CI, is there any quick fix? Test are running locally but not in linux CI / google cloud build and facing the same error on the httpclient...

also running the same test in WSL from vs2022 get me another exception (project not found)..

This test was un-quarantined, but the issue wasn't closed. Closing now.

I'm closing the issue, but if you still get this failure on main then could you please open a new issue so we can track that accordingly? Thanks!
