Purpose of the package details requested when creating an "Azure Applications" offer
I am creating an offer with offer type as "Azure Applications". In SKU tab it asks for "package details", where the publisher is required to upload a zipped package file. I would like understand what is the purpose of this package file the user uploads? How does Microsoft use this file?
The documentation on what has to be included is here: https://docs.microsoft.com/en-us/azure/marketplace/cloud-partner-portal/azure-applications/cpp-skus-tab#package-details-for-solution-template
