eshop-mobile-client

eshop-mobile-client is a reference .NET MAUI multi-platform client app whose imagined purpose is to serve the mobile workforce of a fictitious company that sells products. The app allows you to manage the catalog, view products, and manage the basket and the orders.

Dependencies

Though eshop-mobile-client mobile app relies on the repo eShopOnContainers for its backend but by default it uses its internal MockServices for all its functionalities. For more details refer to the Setup section.

Architecture

The app architecture consists of two parts:

1. A .NET MAUI mobile app for iOS, macOS, Android, and Windows.
2. Several .NET Web API microservices are deployed as Docker containers.

.NET MAUI App

This project exercises the following platforms, frameworks, and features:

• .NET MAUI
  • XAML
  • Behaviors
  • Bindings
  • Converters
  • Central Styles
  • Animations
  • IoC
  • Messaging Center
  • Custom Controls
  • xUnit Tests
• Azure Mobile Services
  • C# backend
  • WebAPI
  • Entity Framework
  • Identity Server 4

Backend Services

All the backend services-related code and components are maintained as eShopOnContainers repo.

Supported platforms

The app targets four platforms:

• iOS
• macOS
• Android
• Universal Windows Platform (UWP)
  • UWP is supported only in Visual Studio for Windows, not Visual Studio for macOS

Requirements

• Visual Studio 2022 (2022 or higher) to compile C# language features (or Visual Studio MacOS)
  • Visual Studio Community Edition is fully supported!
• .NET MAUI add-ons for Visual Studio (available via the Visual Studio installer)

Setup

1. Ensure the .NET MAUI platform is installed

You can do that by following the steps mentioned in Installing .NET MAUI

2. Ensure .NET MAUI is updated

Visual Studio will periodically automatically check for updates. You can also manually check for updates using the Update Visual Studio options.

3. Project Setup

Restore NuGet packages for the project.

4. Ensure Android Emulator is installed

You can use any Android emulator although it is highly recommended to use an x86-based version.

Note: The Visual Studio Android Emulator cannot run well inside a virtual machine or over Remote Desktop or VNC since it relies on virtualization and OpenGL.

To deploy and debug the application on a physical device, refer to the Debug on an Android device article.

5. Ensure Mac connection

To set up the Mac host, you must enable communication between the Xamarin extension for Visual Studio and your Mac.

6. Use Actual Microservices

By default eshop multiplatform client uses the internal mock services to let the user explore different sets of features in the app.

But if you want to test out the app using real services, you can do that too.

For that you'll need to do the following:

1. Deploy the backend services of eShop applications from the eShopOnContainers repo. You can deploy the application to either Local Kubernetes or AKS environments.

2. Enable microservices endpoint in the Settings section.

Identity Url : http://<YOUR_IP_OR_DNS_NAME>/identity Mobile Gateway Shopping Url: http://<YOUR_IP_OR_DNS_NAME>/mobileshoppingapi

3. Enable HTTP traffic.

Android App

You'll also need to include the <YOUR_IP_OR_DNS_NAME> in the section <domain includeSubdomains="true"><YOUR_IP_OR_DNS_NAME></domain> of the network_security_config.xml file to use HTTP traffic.

For more details refer to Managing HTTP & Cleartext Traffic on Android with Network Security Configuration

IOS App

You'll need to make sure your info.plist file contains the following configuration.

  <key>NSAppTransportSecurity</key>
  <dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
  </dict>

For more details refer to Opting-Out of ATS

NOTE: Please note, in production scenario you'll the services which uses HTTPS endpoint.

7. Setup Google Maps for Android

In the eShopOnContainers\Platforms\Android\AndroidManifest.xml you must replace the value of the com.google.android.geo.API_KEY with a valid Google Maps API key.

<meta-data android:name="com.google.android.geo.API_KEY" android:value="YOUR_KEY_GOES_HERE" />

For more details refer to .NET MAUI Map - Get a Google Maps API key.
