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.
Here is a simple example of an XAML page in WPF. It consists of 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!"
