Microsoft Store Developer CLI msstore publish --inputFile supported file extensions .appx .msix .msixupload official documentation

💡 Result:

According to the official Microsoft Store Developer CLI documentation, the --inputFile (or -i) option for the msstore publish command supports the following file extensions:.msix.msixupload The official documentation explicitly identifies these two formats for use with the --inputFile argument [1][2][3]. This argument specifies the path to the package file to be used for the publishing command; if the option is not provided, the CLI attempts to automatically identify the best candidate package based on the project path or URL argument provided to the command [1][2][4]. While some internal Microsoft repositories (such as StoreBroker) may reference a broader list of extensions for internal submission tools [5], the Microsoft Store Developer CLI's public-facing documentation for the publish command exclusively lists.msix and.msixupload [1][2][3].

microsoft/microsoft-store-apppublisher GitHub action v1.1 exact Microsoft Store Developer CLI version and package input format

💡 Result:

The microsoft/microsoft-store-apppublisher GitHub Action is designed to install and configure the Microsoft Store Developer CLI (MSStoreCLI) on a runner [1][2]. Regarding your specific questions about versioning and input format: Microsoft Store Developer CLI Version The GitHub Action accepts an optional input named version, which specifies the version of the MSStoreCLI to download [2]. If this input is not provided, the action defaults to 'latest' [2]. The input is defined in the action's configuration as follows [2]: inputs: version: required: false description: "The version of the Microsoft Store CLI to be downloaded and configured (e.g. 'v0.3.0')." default: 'latest' Package Input Format The microsoft-store-apppublisher action itself does not require a specific package input format, as its primary purpose is to set up the CLI environment on the runner [1][2]. The actual package submission is performed by subsequent steps in your workflow using the msstore publish command [3][4]. When using the msstore publish command, the input format typically requires the local file path to your application package (e.g., an.msix or.msixbundle file) [3][4]. An example usage within a workflow is [3][4]: - name: Publish App package run: msstore publish '${{ github.workspace }}/release/package.msix' -id In this example, the package input is a path string pointing to the build artifact on the runner [3][4].

site:github.com/microsoft/msstore-cli inputFile appx msstore publish source code

💡 Result:

The term inputFile in the context of the Microsoft Store Developer CLI (msstore-cli) refers to the path argument used in the publish command [1]. Specifically, the command msstore publish -i <path> (where -i stands for --input-file or --input-directory) is used to specify the location of the application package to be submitted [1]. Key details regarding this process: 1. Function of -i: The -i flag allows you to point the CLI to the directory or file path containing your packaged application (such as an.msix or.appx package) [2][1]. 2. Not for Source Code: The Microsoft Store CLI does not publish "source code" directly [3][4]. It is designed to publish built application packages (e.g., MSIX, MSI, EXE, or PWAs) [3]. You must build your application into a supported package format using your development environment's tools before using the msstore-cli to upload it to the Partner Center [3][5][1]. 3. Usage Context: Users often use this command in CI/CD pipelines (like GitHub Actions or Azure DevOps) [2][5]. The CLI handles the interaction with the Microsoft Store APIs to create a new submission and upload the package specified by the input path [3][1]. 4. Common Challenges: Users have reported that the CLI often expects the path to point directly to the package or a specific directory structure [2][6]. Furthermore, issues such as the submission hanging at CommitStarted or failing to find files can occur if the project configuration is not correctly set up or if the submission workflow is not properly managed [1][6]. For authoritative guidance, refer to the official Microsoft Store CLI documentation available at https://aka.ms/msstoredevcli/docs [4].

Use a package format supported by --inputFile.

The workflow selects an .appx, but the msstore publish contract lists only .msix and .msixupload for --inputFile. Produce a supported package or convert the artifact before publishing. Also pin the CLI version instead of using the action’s default latest.

`msstore submission updateMetadata` can also drive the Store listing text from a versioned `metadata.json`, which would replace the CSV export/import round-trip. Not wired up here.

**It has submitted nothing yet.** v1.9.5 was the job's first real run — it did not exist on the v1.9.1 or v1.9.2 builds — and it failed: `We could not find a project publisher for the project at …Openscreen.Setup.1.9.5.appx`. Credentials were fine; the CLI reported the configuration valid and resolved the product. The call was wrong. `msstore publish` takes a **project root** as its positional argument, detects the app type there, and only then accepts a built package through `--inputFile`; the job passed the `.appx` positionally and never checked the repo out, so there was no project to detect. Fixed by adding a checkout (before the artifact download — `actions/checkout` cleans the workspace) and calling `msstore publish . --inputFile <appx> --appId <id>`.

That failure was visible only because the same release carried the fix that reports the submission's real outcome instead of the configuration's. The prior version wrote "Submitted to the Store" whenever credentials resolved, under `always()` — so this exact failure would have shipped as a green success.

**Still unverified, and the next thing likely to break:** `--inputFile` is documented for `.msix` and `.msixupload`, and `build:win:store` produces an `.appx` (`electron-builder --win appx`). Whether the CLI accepts that extension is untested.

**There is no dry run, so do not reach for one.** The job is gated to stable tags, so the only ways to exercise it are a real release or a `workflow_dispatch` of `build.yml` with a stable `release_tag` — and neither is a rehearsal. `msstore publish` commits the submission unless it is given `-nc, --noCommit`, which this job does not pass, so a dispatch fired "just to see whether the `.appx` is accepted" creates a submission that enters certification and reaches users. Adding `--noCommit` behind a dispatch input is what a real validation path would need; until someone builds that, assume the Store needs the manual upload below, and treat the next stable release as the test.

Rotate by issuing a new client secret on the Entra registration, updating `AZURE_AD_APPLICATION_SECRET`, publishing one release to confirm, then deleting the old secret. The tenant, client and seller IDs change only when the registration or account does.
