.NET MAUI Tutorial Full Course

The video “.NET MAUI Tutorial Full Course” is an extensive, step-by-step guide covering a wide range of topics related to developing cross-platform applications using .NET MAUI. It includes detailed explanations, practical examples, and best practices for building apps targeting Android, iOS, Mac OS, and Windows from a single codebase.

Below is a structured summary of the key technological concepts, product features, tutorials, and analyses provided:

1. Introduction to .NET MAUI

Develop cross-platform apps with one codebase for Android, iOS, Mac OS, and Windows.
Supports multiple layouts, page types, and third-party libraries.
Uses data binding for automatic UI updates on data changes.
Highly rated and loved framework, supported by Microsoft Visual Studio.

2. Setup and Installation

Guide to installing Visual Studio 2022 Community Edition.
Installing .NET 7 SDK and enabling Hyper-V for Android emulators on Windows.
Setting up Android emulators and configuring devices.
Using physical Android devices for debugging (enabling developer mode, USB debugging, wireless debugging).
Troubleshooting emulator issues (e.g., virtualization in BIOS, task manager to kill hanging emulators).

3. Creating a .NET MAUI App

Creating a new .NET MAUI project targeting .NET 6.
Overview of project structure:
- Dependencies for platform targets.
- Platforms folder for platform-specific code.
- Resources folder for images, fonts, styles.
- App.xaml for application-wide resources.
- AppShell.xaml for navigation and UI shell.
- MainPage.xaml for UI elements using XAML and C# code-behind.
Event handling by linking XAML elements (buttons) to C# methods.

4. Page Types and Navigation

ContentPage: Basic page with vertical stack layout.
FlyoutPage: Side menu that slides in.
TabbedPage: Tabbed navigation with icons.
NavigationPage: Stack-based navigation with navigation bar.
Creating and navigating between pages programmatically.
Setting background colors, text colors, and styling navigation bars.
Using buttons to navigate between pages asynchronously.
Passing data between pages using view models.

5. Layouts and UI Elements

StackLayout: Vertical and horizontal stacking of child elements.
- Properties: Orientation, Margin, Spacing, Padding.
GridLayout: Defining rows and columns, spanning multiple rows/columns.
- RowDefinitions and ColumnDefinitions.
- Positioning elements with Grid.Row, Grid.Column, Grid.ColumnSpan.
FlexLayout: Flexible layout similar to CSS flexbox.
- Direction (Row, Column, Reverse), Alignment (Stretch, Center, Start).
- Nested FlexLayouts for headers, footers, and content areas.
AbsoluteLayout: Explicit positioning using absolute or proportional coordinates.
- LayoutBounds and LayoutFlags for size and position.
Various controls:
- Labels, Buttons, ImageButtons, RadioButtons, CheckBoxes, Switches
- SearchBar, Sliders, Steppers, DatePicker, TimePicker
- Entry, Editor, SwipeView
Demonstrations of binding control events to C# methods.
Using images as buttons and custom fonts.

6. Data Binding

Binding data sources to UI controls for automatic updates.
Ways to bind:
- Programmatically creating bindings in C#.
- Defining data sources in XAML with StaticResource.
- Using BindingContext for the entire page.
Binding between controls (e.g., slider value bound to label text).
Explanation of one-way and two-way bindings.

7. MVVM Pattern in .NET MAUI

Explanation of Model-View-ViewModel (MVVM) pattern:
- Model: Data objects (e.g., Customer, Player).
- View: UI pages (XAML).
- ViewModel: Connects Model and View, handles logic, commands, and properties.
Organizing projects into folders: Models, Views, ViewModels.
Creating models with properties.
Creating view models with observable collections and INotifyPropertyChanged.
Binding views to view models.
Commands for handling UI events without code-behind.
Examples:
- Customer info app with editable fields (Entry, Switch, DatePicker).
- Passing data between pages using view models.
- Calculator app demonstrating two-way binding and commands.

8. Collections and Dynamic UI

Using ObservableCollection for dynamic lists.
ListView and CarouselView to display collections of data-bound items.
Customizing item templates with DataTemplate.
Using resource dictionaries for styling separation.
Dynamic styling using DataTemplateSelector to change UI based on data (e.g., highlight Pro Bowl players).
CollectionView with headers, footers, grid layouts, horizontal and vertical orientations.
Responsive UI design with dynamic item spans and layouts.

9. Advanced UI Features

SwipeView for swipe gestures revealing menu items (e.g., favorite, delete).
Using SVG icons and custom fonts for UI elements.
Using resource dictionaries for reusable styles.
Performance considerations like XAML compilation.

10. Troubleshooting and Best Practices

Enabling virtualization and Hyper-V for emulator performance.
Using physical devices for testing.
Organizing code for maintainability.
Using MVVM pattern to separate concerns.
Using commands instead of event handlers for UI actions.
Using binding contexts and resource dictionaries for cleaner code.
Leveraging layout options for responsive design.
