Customers Orders Database sample

A Universal Windows Platform (UWP) sample app that showcases UI controls (including a data grid) and the latest design guidance for apps on Windows 11. It also demonstrates features useful to enterprise developers, like Azure Active Directory (AAD) authentication, Sqlite and SQL Azure database integration, Entity Framework, and cloud API services. The sample is based around creating and managing customer accounts, orders, and products for the fictitious company Contoso.

Note - This sample is targeted and tested for Windows 11 Insider Preview using the Insider Preview SDK Build 22000, and Visual Studio 2019. If you are developing on Windows 10, retarget the Contoso.App project to Windows 10, version 2004 (10.0; Build 19041).

Previous updates

June 2020 update

This update includes:

  • Update to WinUI 2.4
    • Add Microsoft.UI.Xaml NuGet package reference
    • Update <Application.Resources> in App.xaml
  • Refactoring for the following WinUI 2.4 controls:



This sample highlights:

  • The list/details UI pattern
  • An editable DataGrid control
  • Form layouts
  • Authenticating and obtaining user info using Azure Active Directory (AAD)
  • Using the repository pattern to connect to Sqlite or SQL Azure databases
  • Connecting to an external web API built with ASP.NET Core 2.0

This sample is designed to cover the core scenarios with minimal architectural complexity. For a more complex, full-featured sample that covers many of the same scenarios using a more sophisticated architecture, see the VanArsdel Inventory sample.

Run the sample

This sample is designed to connect to an instance of Azure Active Directory for authentication and an external service for data. To get you started right away, we've provided some demo data and a test service you can connect to. However, in order to debug and explore the full functionality of the app, you'll need to deploy your own instance to Azure.

Quick start

Prepare your environment

  • Windows
    • Windows 11 Insider Preview (Build 22000).
    • Windows 10. Minimum: Windows 10, version 1809 (10.0; Build 17763), also known as the Windows 10 October 2018 Update.
  • Windows 10 SDK. Minimum: Windows SDK version 10.0.17763.0 (Windows 10, version 1809).
  • The .NET Core 2.0 SDK.
  • Visual Studio 2019. You can use the free Visual Studio Community Edition to build and run Windows Universal Platform (UWP) apps.

To get the latest updates to Windows and the development tools, and to help shape their development, join the Windows Insider Program.


Set your startup project as Contoso.App, the architecture to x86 or x64, and press F5 to run.

Complete setup

To fully explore the sample, you'll need to connect to your own Azure Active Directory and data source. Values you need to fill are in Constants.cs.

  • Client Id: Set the AccountClientId field to your Azure account client Id.
  • API endpoint: Set the value of the BaseUrl constant to match the url the backing service is running on.
  • Set a database connection string: Set the connection string to one of your own local or remote databases.
  • Associate this sample with the Store: Authentication requires store association. To associate the app with the Store, right click the project in Visual Studio and select Store -> Associate App with the Store. Then follow the instructions in the wizard.

You can then either start the service running locally, or deploy it to Azure.

  • To run locally, right-click the solution, choose Properties, and choose to start both Contoso.App and Contoso.Service at the same time.
  • To deploy to Azure, right-click Contoso.Service, choose Publish, and then follow the steps in the wizard.

Code at a glance

Design patterns


The Orders list screen displays a list of orders. It uses visual state triggers to selectively display an additional details panel when the screen is large enough. To see the full details of an order or to edit it, the user selects "Edit" to go to the Order details screen. The Order details screen shows all the info for the order and enables editing. The user can search for additional products to add to the invoice.

Form layouts

The two details screens show how to use headings, labels, and whitespace to organize controls into a form layout. Some controls used include:
