To build a Maui app with C# ASP.NET and Entity Core, you can follow the recommended architectural pattern, which is the Model-View-ViewModel (MVVM) pattern or MVC.

Here's a step-by-step guide on how to structure your Maui app using this architecture:

1. Create a new Maui project in Visual Studio or Visual Studio for Mac.

2. Separate the different layers of your app by creating folders for Models, Views, ViewModels, and Services.

3. Models: This is where you define the data structure and properties used in your app. Create separate model classes for each entity using Entity Framework Core, and define the necessary properties and relationships.

4. Services: Create a Services folder and add service classes that will handle the data operations, such as fetching data from a database using Entity Framework Core. These services should interact with the entity models and provide methods for retrieving, updating, and deleting data.

5. Views: Your Maui app will have different views for displaying data and interacting with the user. Create separate view classes for each of these views, and define the UI components and layout using XAML.

6. ViewModels: ViewModels act as the intermediaries between the views and the services. Create separate ViewModel classes for each view, and define properties and commands that will be bound to the UI controls in the view. These ViewModels will interact with the services to retrieve and manipulate data.

7. IoC Container: In addition to the above folders, you can also create a separate folder for an IoC (Inversion of Control) container like Castle Windsor or Unity. This can help with dependency injection and managing dependencies between different classes.

8. Wiring everything together: In your app's entry point (e.g., `App.xaml.cs` or `Program.cs`), configure your IoC container if you're using one, and set up the necessary dependencies between the views, view models, and services. This may involve registering the necessary services with the IoC container and ensuring that the views are bound to their corresponding view models.

9. Build and run your Maui app to see the architecture in action.

By following the above steps, you should have a solid architectural foundation for your Maui app using C# ASP.NET and Entity Core. Remember to keep the responsibilities of each layer separate and make use of the MVVM pattern to handle data and UI interactions effectively. Note the WebAPI is hosted in platform like Azure or Hostinger (an endpoint) and the JSON Data binding in c# using MAUI for the app.

Tools

Visual studio 2022
SQL server and SQL management studio
Windows 10 or windows 11

Environments

Entity framework core(EFCore)

.NET 8
MAUI community toolkit

Creating full-fledged MAUI (Multi-platform App UI) apps in C# involves a few straightforward steps:

1. *Install Prerequisites:*
Ensure you have the necessary tools installed, including .NET MAUI workload, Visual Studio 2022, and the required SDKs. You can get the latest versions from the official Microsoft website.

2. *Create a New MAUI Project:*
Open Visual Studio 2022, select "Create a new project," and choose the "MAUI App" template. This will provide you with a basic project structure.

3. *Design User Interface:*
Utilize XAML for designing the user interface of your app. MAUI uses a single project structure for both Android and iOS, making it easy to create a shared UI.

4. *Implement Functionality in C#:*
Write your app's logic in C#. You can leverage the power of .NET to create cross-platform functionalities while utilizing platform-specific code when needed.

5. *Test Across Platforms:*
Utilize the built-in emulators or connect physical devices to test your app on different platforms. Ensure your app behaves as expected on both Android and iOS.

6. *Add Platform-Specific Code (if necessary):*
If your app requires platform-specific features, use Dependency Injection or Dependency Service to add platform-specific code while maintaining a shared codebase.

7. *Optimize for Each Platform:*
Fine-tune your app's performance and user experience for each platform. Address any platform-specific nuances or design considerations.

8. *Handle Lifecycle Events:*
Implement code to handle application lifecycle events appropriately. Ensure your app behaves well when users switch between apps or when the device enters different states.

9. *Debug and Test Thoroughly:*
Debug your app to identify and fix any issues. Perform thorough testing on various devices and screen sizes to ensure a consistent experience.

10. *Publish Your App:*
Once you're satisfied with your MAUI app, publish it to the respective app stores. Follow the guidelines provided by Microsoft for app submission and publication.

Keep in mind that the MAUI framework is evolving, so it's advisable to refer to the latest documentation and community resources for any updates or changes to best practices.

When looking for genuine Microsoft products like Visual Studio and Windows 11, consider exploring well-known and authorized online retailers or the official Microsoft Store. These platforms are reliable sources for obtaining legitimate software licenses and ensuring the authenticity of your Microsoft products. Always be cautious and verify the reputation of any online store to avoid potential risks associated with counterfeit or unauthorized products.

Note you can build an app with ASP.NET Core minimal API in .NET 8 with entity framework or SQLite and MAUI in C# . You can deploy your API endpoints to Azure or any .NET platforms that support NET 8 for production. You can also test your code on your app using localhost and dev tunnels .
