Introduction
In this section we will show how to display a dark and light theme in a Windows 8 Metro Style application. In this example we show light and dark themes with contents like toggle switch, hyperlink content, radio button content and checkbox content. When the toggle switch value is off then the dark theme is displayed. In this example we will present two points; the first point demonstrates how to apply a light theme including light styles and templates and second point demonstrates how to create a builtin dark theme style and templates.
So, we will use the following steps to make this application as below.
Step 1 : First of all you will create a new Metro Style Application. Let us see the description with images of how you will create it.
- Open Visual Studio 2011
- File -> New -> Project
- Choose Template -> Visual C# -> Windows Metro Style -> Application
- Rename this Application

Step 2 : In the Solution Explorer there are two files that we will primarily work with; MainPage.xaml and MainPage.xaml.cs files. In the images folder add any image to the application but in this application we don't have to add an image.

Step 3 : The MainPage.xaml file is as in the following code.
Code : Let us see the code which is given below:
