Visual Studio on Windows or Visual Studio for Mac offers a user-friendly interface with features like code completion and debugging, and it has a visual designer specifically tailored for .NET MAUI development.

Creating Your First .NET MAUI App:

With the prerequisites in place, let’s create a brand new .NET MAUI application project:

  1. Launch your chosen IDE (Visual Studio or Visual Studio for Mac).
  2. Navigate to the “Create a new project” option.
  3. Within the project templates, search for “.NET MAUI” and select the appropriate template based on your target platforms (Android, iOS, macOS, Windows, etc.).
  4. Provide a name for your project and solution (usually the same) and choose a suitable location to save your project files.
  5. Click “Create” to initiate the project creation process.

Understanding the Building Blocks of .NET MAUI:

A .NET MAUI application UI is constructed from fundamental elements that work together to deliver an interactive experience. Here’s a breakdown of these key components:

  • Pages: These are the individual screens that make up your application. Each page can house UI elements and define the layout for the content displayed to the user.
  • Layouts: Layouts act as containers that organize and position UI elements within a page. .NET MAUI offers various layout options like StackLayout (elements stacked vertically), Grid (flexible grid-based layout), and AbsoluteLayout (precise positioning of elements).
  • Controls: These are the interactive building blocks that users interact with. Buttons, labels, text boxes, lists, and images are all examples of controls available in .NET MAUI. Each control has properties that define its appearance and behavior.

Building a Simple UI:

Let’s get your hands dirty by creating a basic UI with some common controls:

  1. Open the main page of your newly created project (often named MainPage.xaml).
  2. Within the XAML code, you’ll see elements defining the page structure.
  3. Locate the section where child elements are added to the page’s layout container.
  4. Try adding controls like a Button with some text, a Label to display information, and a TextBox for user input. Use the control’s properties to customize their appearance (e.g., font size, background color).

By following these steps, you’ll have created a rudimentary .NET MAUI application with interactive elements. This serves as a springboard for building more complex and visually appealing UIs with the power of XAML and its advanced features.

Now that you’ve created your first basic .NET MAUI application let’s explore the building blocks that will bring your UIs to life: controls and layouts.

Controls and Layouts in .NET MAUI: Building Your UI Toolbox

The user interface (UI) of your .NET MAUI application is where users interact with your app.  .NET MAUI provides a rich set of controls and layout options to bring your UI vision to life.

Essential Controls:

.NET MAUI offers a rich set of controls that cater to various user interaction needs. Here’s a glimpse into some fundamental controls:

  • Buttons: These are the workhorses of any UI, allowing users to trigger actions. You can customize button text, size, and background color to match your application’s design.
  • Text Input: Text boxes and entry fields enable users to enter data. Properties like placeholder text and keyboard type (numeric, email) enhance the user experience.
  • Sliders: Provide a visual way for users to select a value from a continuous range. Ideal for adjusting settings like volume or brightness.
  • Pickers: Offer a dropdown menu with predefined options for users to choose from. Useful for selecting items like categories or preferences.
  • List Views: Display scrollable lists of items, ideal for showcasing data or navigation options. List views can be customized to display text, images, or even custom UI elements for each item.

These are just a few examples, and .NET MAUI provides a comprehensive library of controls to suit diverse application requirements.  Remember, each control has a set of properties that allow you to tailor its appearance and behavior to your specific needs.

Layout System: Arranging Your UI Elements

Layouts play a crucial role in organizing and positioning controls within a page.  .NET MAUI offers various layout options to achieve different UI structures:

  • StackLayout: This layout stacks controls vertically (one on top of another) by default. You can modify the orientation to arrange them horizontally if needed. StackLayout is ideal for creating simple, linear UIs.
  • Grid: Provides a flexible grid-based layout system. Imagine a table with rows and columns where you can place controls in specific cells. This layout offers more control over positioning elements within the page.
  • AbsoluteLayout: Grants precise control over the placement of controls using absolute coordinates. While powerful for complex layouts, AbsoluteLayout requires careful planning to avoid UI inconsistencies across different screen sizes.

By understanding these core layout options and their functionalities, you can create well-organized and visually appealing user interfaces for your .NET MAUI applications.

Visualizing Layouts:

Imagine you’re building a simple login screen. A StackLayout would be suitable for vertically stacking a label for the app logo, an entry control for username, another entry control for password, and a button for logging in.

On the other hand, if you’re designing a product catalog with images and descriptions, a Grid layout might be more appropriate. You can define rows and columns to arrange product images and descriptions in a grid-like structure, creating a visually organized product listing.

By effectively combining controls and layouts, you can construct intuitive and visually appealing user interfaces for your .NET MAUI applications.

Navigating Through Your .NET MAUI App: A Seamless User Journey

In a multi-screen application, users expect a smooth and intuitive way to move between different functionalities. .NET MAUI provides robust navigation features to craft a seamless user experience within your app.

Navigation Basics: 

  • Push-Pop Navigation: This approach is akin to a stack of pages.  When you navigate from one page to another using the PushAsync method, the new page is pushed on top of the navigation stack.  The user can then “pop” back to the previous page using PopAsync.  Imagine a settings page being pushed on top of the main screen and then popping back after configuration changes.
  • Hierarchical Navigation:  This navigation style establishes a parent-child relationship between pages, creating a more structured hierarchy.  This is useful for scenarios where you have nested functionalities.  For instance, a product listing page could act as a parent, “pushing” users to individual product detail pages (children) upon selection.

Sharing Information Across Pages: 

Applications often require exchanging data between different screens.  .NET MAUI’s navigation parameters enable you to pass data from one page to another during navigation. This data can be used to populate content, customize the behavior of the receiving page, or maintain the application state.

Imagine a product listing page passing the selected product information (ID or name) to a product detail page using navigation parameters.  The detail page can then retrieve this data to display specific product details relevant to the user’s selection.

By mastering these navigation techniques, you can ensure a logical and user-friendly flow within your .NET MAUI application, guiding users through various functionalities and maintaining a clear context throughout their journey.
