1.5 WPF

WPF stands for Windows Presentation Foundation. It’s a UI (User Interface) framework developed by Microsoft for building Windows desktop applications.

1. 💡 What is WPF Used For?

WPF is used to create:

Rich desktop applications with graphical interfaces
Applications with modern UI designs (e.g., animations, styles, themes)
Data-driven apps (like dashboards, form-based apps)

1.1 Key Features

Feature	Description
XAML	Uses XML-based markup to design UI declaratively (`.xaml` files).
Data Binding	Connects UI controls to data models (e.g., MVVM pattern).
Vector Graphics	UI scales smoothly on high-DPI screens.
Styles and Templates	Customize the appearance of controls.
Animations	Built-in support for rich UI transitions.
Hardware Acceleration	Uses DirectX for fast rendering.

1.2 🛠 Example

XAML (UI layout):

<Window x:Class="MyApp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        Title="Hello WPF" Height="200" Width="300">
    <Grid>
        <Button Content="Click Me" Width="100" Height="30"/>
    </Grid>
</Window>

C# (Code-behind):

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }
}

1.3 Technologies it builds on:

.NET (Framework or Core/5+/6+/7+)
XAML for UI
MVVM (Model-View-ViewModel) is the common architecture

1.4 ✅ When to Use WPF

You’re building a Windows-only desktop app
You want a custom, modern UI
You need data binding, templates, animations, or advanced layout

1.5 ❌ When not to Use WPF

If you’re building cross-platform apps → use MAUI, Electron, or web apps
If you only need basic UI → WinForms might be simpler
