Windows apps reach the Microsoft Store through Partner Center. There you register as a developer, create your app as a product, and manage submissions. The platform later submits through the Store submission API and needs an app registration in Microsoft Entra ID that is authorized in Partner Center. For that, the Partner Center account must be associated with an Entra tenant.
Register as a developer in Partner Center
- Open partner.microsoft.com/dashboard and sign in with a Microsoft account.
- Register as a Windows app developer (Windows Developer Account) and complete the identity verification.
- Note the Seller ID under Account settings → Legal info or Identifiers. The platform asks for it when you store the credentials.
Associate an Entra tenant
The app registration for the pipeline lives in a Microsoft Entra ID tenant. Therefore associate a tenant with the Partner Center account; you can use an existing tenant of your organization or create a new one. You need administrator rights both in the tenant, to manage app registrations, and in Partner Center, to authorize users and applications. Microsoft describes the association under Associate an Entra tenant with Partner Center.
Create the app in Partner Center
- Create the Windows app as a product in Partner Center.
- Do the first publication, including the age rating, manually in Partner Center. Microsoft typically asks for these details only on the first submission.
- Note the Product ID (Store ID) of the app. It links the Windows project to the store listing in the platform.
Once the account, tenant, and product exist, create the app registration and store it as described under Microsoft Store credentials.
