Summary

v1.9.6's Store submission failed three times in a row, always at the same place: submission created, bundle prepared, then Uploading Bundle to Azure blob: 0% and Error while uploading the application package. about 22 s later. Same .appx (335 MB — byte-for-byte the size that shipped for 1.9.5), same product, same command, and the identical submission had succeeded on 2026-08-15.

Two commits: one makes the failure legible, one fixes it.

1. -v, because the CLI otherwise tells you nothing

Without it the entire diagnosis is one unqualified sentence with no status code, no URL and no body. With it:

Retry failed after 6 tries.
The operation was cancelled because it exceeded the configured timeout of 0:00:00.
Network timeout can be adjusted in ClientOptions.Retry.NetworkTimeout.

NetworkTimeout is zero, so every request is cancelled the instant it starts. Six instant retries is the whole 22 seconds — nothing was ever put on the wire, which is why no HTTP status appears anywhere in the failure.

2. Pin the CLI

The variable was never ours. microsoft/microsoft-store-apppublisher defaults to version: latest, and msstore-cli v0.4.0 was published 2026-08-18T09:09Z — the first release since v0.3.9 in January, and hours before the first failure. The 15 August success ran v0.3.9.

Pinned to v0.3.9 in both places that configure the CLI — publish-msstore.yml and build.yml's publish-msstore job. Pinning only one would leave the release path broken while the retry path worked, which is the worst kind of half-fix to debug later.

Refs #385 — the reporter installed from the Store, so this is the last thing standing between that fix and them.

Testing

Proven end to end by dispatching publish-msstore.yml on this branch (workflow_dispatch takes any ref, so no merge was needed to test it) against the real v1.9.6 tag with dry_run=false:

Uploading Bundle to Azure blob: 13%
Uploading Bundle to Azure blob: 76%
✅ Successfully uploaded the application package.
Submission Committed - Status=CommitStarted
Submission commit success!
SUBMIT: success

Run 32196525978, 7m52s. v1.9.6 is now submitted and in certification — this PR is what stops the next release hitting the same wall.

The three failures for the record: 32190106274 (in the release build), 32192781855, 32194618175.

Summary by CodeRabbit

  • Bug Fixes

    • Improved Microsoft Store package publishing reliability by using a verified publishing tool version.
    • Added detailed diagnostic output when uploads fail, including status information and service responses.
  • Chores

    • Stabilized automated Microsoft Store release workflows with consistent publishing configuration.
    • Improved troubleshooting for failed package submissions by exposing more actionable upload details.

v1.9.6's Store submission failed three times in a row, always at the same
place: submission created, bundle prepared, then "Uploading Bundle to Azure
blob: 0%" and "Error while uploading the application package." ~22 s later.
Same appx (335 MB, byte-for-byte the size that shipped for 1.9.5), same
product, same command -- and the identical submission had succeeded on
2026-08-15.

`-v` is what made it diagnosable, so it stays:

  Retry failed after 6 tries.
  The operation was cancelled because it exceeded the configured timeout of
  0:00:00. Network timeout can be adjusted in ClientOptions.Retry.NetworkTimeout.

NetworkTimeout is ZERO, so every request is cancelled the instant it starts;
six instant retries is the whole 22 seconds. Nothing was ever sent, which is
why there is no HTTP status anywhere in the failure.

The variable is the CLI, not us: `microsoft/microsoft-store-apppublisher`
defaults to `version: latest`, and msstore-cli v0.4.0 was published
2026-08-18T09:09Z -- the first release since v0.3.9 in January, and hours
before the first failure. The 15 August success ran v0.3.9.

So pin v0.3.9 in both places that configure the CLI: publish-msstore.yml and
build.yml's publish-msstore job. Pinning one would have left the release path
broken while the retry path worked, which is the confusing half-fix.

📝 Walkthrough

Walkthrough

The Microsoft Store workflows pin the CLI to v0.3.9. The publish commands also enable verbose output for upload diagnostics.

Changes

Microsoft Store publishing

Layer / File(s) Summary
Pin Microsoft Store CLI version
.github/workflows/build.yml, .github/workflows/publish-msstore.yml
Both workflows pin the Microsoft Store CLI to v0.3.9. Comments document the upload timeout issue in newer CLI versions.
Enable verbose publish output
.github/workflows/build.yml, .github/workflows/publish-msstore.yml
The msstore publish commands add -v so upload failures include the status code, URL, and response body.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 4c3da

The workflows pin the Store CLI to the known-good version in both release paths, preventing the reported upload failure; no actionable merge-blocking risk remains beyond normal checks and review.

Comment thread .github/workflows/publish-msstore.yml
CodeRabbit caught a half-fix, and it is exactly the one this PR's own commit
message warns about for the pin: the CLI version got pinned in both call sites,
but `-v` only went onto publish-msstore.yml. So the retry path would explain an
upload failure and the RELEASE path -- the one that actually runs on a tag, and
the one that failed for v1.9.6 -- would still print the bare "Error while
uploading the application package." with nothing to act on.

Both invocations now carry it.
