Package Uploader is an open source .NET based cross-platform application and library that enables game developers to interact programmatically with Partner Center. Package Uploader has a command-line tool and a dynamic linked library (DLL) that you can integrate into your build pipelines or other development workflows and provides the following functionality:
  • Retrieves metadata about a particular product
  • Uploads a new XBOX .xvc, .appx, or .msixvc package
  • Removes previously uploaded packages
  • Imports packages from one branch to another
  • Publishes packages to a sandbox
For MSIXVC2 packages, you can also use the built-in makepkg upload command, which combines packaging and uploading in a single step with support for multiple authentication methods. See Make package (makepkg.exe).
