Create Your Microsoft Partner Account
To build an app that you can publish to the Microsoft App Store, Deskifier needs some specific details from your Microsoft Partner Center dashboard.
- Navigate to storedeveloper.microsoft.com/onboarding and complete the Microsoft Store developer onboarding.

- Once you've completed the onboarding, click the Go to Partner Center dashboard button.

- Select Apps and games.

- Create a new product. Select MSIX or PWA app as the product type.

- Navigate to Product identity. Here you'll find the information Deskifier needs to build your appx package.

- After entering the details into the Deskifier dashboard, you can create a new submission, and navigate to the Packages section.

Once you have downloaded your build from Deskifier, upload the appx file here.
