C# sample: app submission with game options and trailers
This article provides C# code examples that demonstrate how to use the Microsoft Store submission API for these tasks:
- Obtain an Azure AD access token to use with the Microsoft Store submission API.
- Create an app submission
- Configure Store listing data for the app submission, including the gaming and trailers advanced listing options.
- Upload the ZIP file containing the packages, listing images, and trailer files for the app submission.
- Commit the app submission.
You can review each example to learn more about the task it demonstrates, or you can build all the code examples in this article into a console application. To build the examples, create a C# console application named DevCenterApiSample in Visual Studio, copy each example to a separate code file in the project, and build the project.
Prerequisites
These examples have the following requirements:
- Add a reference to the System.Web assembly in your project.
- Install the Newtonsoft.Json NuGet package from Newtonsoft to your project.
Create an app submission
The CreateAndSubmitSubmissionExample class defines a public Execute method that calls other example methods to use the Microsoft Store submission API to create and commit an app submission that contains game options and a trailer. To adapt this code for your own use:
- Assign the
tenantIdvariable to the tenant ID for your app, and assign theclientIdandclientSecretvariables to the client ID and key for your app. For more information, see How to associate an Azure AD application with your Partner Center account - Assign the
applicationIdvariable to the Store ID of the app for which you want to create a submission.
