Automate Microsoft Store Publishing Across All Languages
Ship updates in minutes — not hours.
App Publisher for Microsoft Store (APfMS) uses your existing .resx or .resw localisation files to automatically update your entire Store listing — across all languages, in a single run.
Whether you publish via API or export a CSV package, APfMS eliminates the repetitive manual work of multilingual Store submissions.
The Problem
Publishing a multi-language app to the Microsoft Store doesn't scale. Every release means:
- Manually updating descriptions, keywords, and metadata for each language
- Copy-pasting screenshots and promotional art across dozens of listings
- Filling out the same web forms over and over in Partner Center
- Waiting hours to discover submission errors after the fact
- No way to keep Store content in sync with your localisation files
As the number of supported languages grows, this process becomes a bottleneck that slows down every release.
The Solution — App Publisher for Microsoft Store
APfMS reads your translated .resx and .resw resource files, maps them to Store fields, validates everything locally, and publishes — either directly via Partner Center API or as a ready-to-import CSV package.
Define your Store content once using simple Publish_* keys in your localisation files. Update values before each release and APfMS keeps your entire Store listing in sync automatically.
Two publishing modes. All languages. One click. Minutes instead of hours.
Key Features
Direct API Publishing
Submit directly to Partner Center with live progress tracking. APfMS clones your listing, uploads assets, and submits automatically.
CSV Export (Offline Mode)
Generate a complete Store Import package (CSV + assets) for manual upload. No API setup or credentials required.
All Languages, One Click
Update every language simultaneously from your localisation files — no more copy-pasting in Partner Center.
Auto-Map Fields
Automatically match all Store fields to your resource keys in one click. Zero manual mapping required.
Local Validation
Catches validation errors locally before you submit — saves hours of waiting for Store rejection feedback.
Full Asset Upload
Uploads screenshots, Store logos, promotional art, and video trailers automatically for every language.
Package Support
Supports MSIX, MSIX Bundle, AppX, and AppX Bundle packages out of the box.
.resx & .resw Support
Works with both WPF-style (.resx) and UWP/WinUI-style (.resw) resource file structures. No migration required.
