Hello World

Here is a simple example of an XAML page in WPF. It consists of a Grid , a TextBlock and a Button - the most common elements in XAML.

<Window x:Class="FirstWpfApplication.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        mc:Ignorable="d"
        Title="MainWindow" 
        Height="350"
        Width="525">
    <Grid>
        <TextBlock Text="Welcome to XAML!"
                   FontSize="30"
                   Foreground="Black"
                   HorizontalAlignment="Center"
                   VerticalAlignment="Center"/>
        
        <Button Content="Hello World!"
                Background="LightGray"
                Foreground="Black"
                FontSize="25"
                Margin="0,100,0,0"
                VerticalAlignment="Center"
                HorizontalAlignment="Center"/>
    </Grid>
</Window>

<Grid>	A layout panel that arranges its child elements in a tabular structure of rows and columns.
<TextBlock>	Provides a lightweight control for displaying string text in its Text property or Inline flow content elements, such as Bold, Hyperlink, and InlineUIContainer, in its Inlines property.

Installation or Setup

The easiest way to get writing your first XAML is to install Microsoft Visual Studio. This is avaliable free from Microsoft.

Once installed you can create a new project, of type WPF Application, either with a VB.NET or C# code.

This is similar to windows forms in the sense that you have a series of windows, the main difference being that these windows are written in XAML and are much more responsive to different devices.

Still needs improvment.
