🤖 Aspire triage pass — 2026-05-28 07:48 UTC

Area: area-cli
Kind: bug (NOT a 13.4 regression — reporter notes "Also reproes on Aspire 13.3.5")
Repro: yes-minimal — body lines 31–47 give clean step-by-step repro on Win11 + SDK 10.0.301 + Aspire CLI 13.4 staging
Affected version(s): 13.4.0 (staging build 3f0998a) and 13.3.5 (latest released)
Severity: S2 — core CLI scenario (aspire add after aspire run --detach + aspire stop) fails with "Unable to stop one or more running Aspire AppHost instances"; no workaround documented in the report

Urgency: 🟡 vNext — recommend milestone 13.5
Reason: S2 with a clean repro in area-cli, but the reporter confirms it reproduces in 13.3.5, so this is a pre-existing bug, not a new-in-13.4 regression. With 13.4 already snapped and shipping next Monday, pulling a non-regression bugfix in needs a human call — defaulting to 13.5.

Suggested owner(s): @JamesNK (score 25+), backup @mitchdenny (score 6)

Confidence: high (on area + owner); medium (on milestone — a human may want this in 13.4 if it's deemed a CLI showstopper for the new --detach flow)
Needs human?: yes — confirm whether this should be pulled into 13.4 despite reproducing in 13.3.5 (decision belongs to release team)

Dry-run mode — no labels or milestone applied. Reply /triage apply to promote, or edit and reapply.

Not a regression, putting in 13.5.

This issue also reproduces after executing aspire run and then executing aspire add

[davidfowl]

I was able to reproduce a related failure with the 13.4 CLI on PATH using the newer foreground-run variant from the latest comment:

aspire new aspire-starter --name AspireStarterApp
cd AspireStarterApp\AspireStarterApp.AppHost
aspire run
# stop with Ctrl+C
aspire add Aspire.Hosting.Azure --non-interactive

Result: aspire add exits with code 5 and reports:

Unable to stop one or more running Aspire AppHost instances. Please stop the application and try again.

The local evidence points to a stale auxiliary backchannel socket. After Ctrl+C, the aspire run log shows the CLI receives the termination signal, cancels the AppHost wait, and kills the AppHost while it is still Hosting stopping. The AppHost process is gone, but its auxiliary socket file remains under the CLI backchannel directory. The following aspire add finds that stale socket, attempts to connect to it, gets Connection refused, and treats that as StopFailed instead of pruning/ignoring the stale socket.

I did not reproduce the original aspire run --detach + aspire stop + aspire add sequence on macOS with the same 13.4 CLI on PATH; that path stopped cleanly and aspire add Aspire.Hosting.Azure --non-interactive succeeded. The original Windows/CMD detach+stop failure may be the same stale-socket issue, but I have only confirmed the foreground aspire run variant locally so far.
