This directory turns the Compose Desktop Windows app image into the unsigned MSIX artifacts accepted by Partner Center. Microsoft signs the package after certification, so this build does not use a PFX, certificate, HSM, or signing secret.

Product identity

These values came from the Partner Center Product identity page and are case-sensitive:

Field	Value
Package identity name	SudosyLabs.Vnidrop
Publisher	CN=6456DC8E-2C31-44BD-AACC-2E6813C833CB
Publisher display name	Sudosy Labs
Reserved Store name	Vnidrop
Application ID	VniDrop
Store ID	9NJ5Q0FG7TGL

The package identity name, publisher, and Application ID must remain stable after the first release. The manifest display name uses the exact reserved Store name; the product's in-app branding and launcher remain VniDrop.

The initial package targets Windows Desktop x64, Windows 10 version 2004 (build 19041) or later. The product version comes from version.properties. Because MSIX requires a non-zero major and reserves the fourth component, the package version adds WINDOWS_VERSION_EPOCH to the product major. With epoch 1, product version 0.2.0 becomes package version 1.2.0.0.

GitHub Actions

The Windows Store package workflow runs automatically for relevant pull requests and by manual dispatch. The coordinated release workflow also calls it for a canonical vMAJOR.MINOR.PATCH tag. Pull requests build and validate without retaining an artifact. Manual and coordinated-release runs retain:

VniDrop_VERSION_x64.msix
VniDrop_VERSION_x64.msixupload
build metadata
SHA-256 checksums

The preferred Partner Center upload is the msixupload file. It is an upload envelope containing the x64 MSIX. The MSIX is intentionally unsigned and is not a public sideloading artifact. Do not attach it to a public GitHub Release unless an independent production-signing path is added.

The workflow explicitly selects Gobley's release Rust variant and rejects a package containing the debug native JAR. It also verifies the bundled JVM, vnidrop.dll, app version, manifest identity, architecture, and launcher after MakeAppx unpacks the finished package.

First Store release

Microsoft's current GitHub Actions publishing flow is for updates to an already-live free product. For the first release:

Push a canonical release tag to run the coordinated workflow, or run the Windows package workflow manually.
Download the retained artifact.
Test that exact build on an interactive Windows VM. Local installation needs an ephemeral development signature trusted only by that VM; this is not a production signing key.
Upload the msixupload file to the current Partner Center draft.
Confirm that Partner Center parses the expected identity, version, x64 architecture, Windows.Desktop target, en-US language, and runFullTrust capability.
Complete listing, screenshots, certification notes, and submit.

Use this restricted-capability justification in Submission options:

VniDrop is a classic JVM desktop application that loads its bundled native Rust and JVM libraries and needs normal user-level filesystem and network access to transfer user-selected files directly between devices.

After the first release is certified and live, the coordinated release workflow submits the generated .msixupload from a separate protected job. Keep its Partner Center credentials in the microsoft-store GitHub Environment, not in the build job:

AZURE_AD_TENANT_ID
AZURE_AD_APPLICATION_CLIENT_ID
AZURE_AD_APPLICATION_SECRET
SELLER_ID

Set MICROSOFT_STORE_PRODUCT_ID to 9NJ5Q0FG7TGL as a non-secret variable in the same environment. The publishing job validates the product ID, authenticates with the pinned Microsoft Store Developer CLI, verifies access to the product, and submits only the package for certification. Existing listings, pricing, and availability are preserved.

Manual build on Windows

From the repository root:

.\gradlew.bat :shared:jvmTest :desktopApp:createReleaseDistributable -Pvnidrop.desktop.rustVariant=release -Pvnidrop.diagnostics.included=false --no-daemon --no-configuration-cache --stacktrace

.\packaging\windows\build-msix.ps1 -AppImage .\desktopApp\build\compose\binaries\main-release\app\VniDrop -OutputDirectory .\build\release\windows

The packaging script requires Windows SDK 10.0.26100.0. It uses MakePri to index the scale-qualified visual assets, then MakeAppx with SHA-256 block maps and manifest validation enabled.
