In this step you'll begin in Visual Studio to create a WPF application using ColorPicker for WPF. When you add a C1ColorPicker control to your application, you'll have a complete, functional color input selector.

To set up your project and add a C1ColorPicker control to your application, complete the following steps:

1. Create a new WPF project in Visual Studio.
2. Navigate to the Toolbox and double-click the Rectangle icon to add the standard control to the Grid.
3. Resize the window, and resize the rectangle to fill the window.
4. Switch to XAML view and add a Fill to the <Rectangle> tag so it appears similar to the following:

XAML	Copy Code
<Rectangle Name="Rectangle1" Stroke="Black"> <Rectangle.Fill> <LinearGradientBrush x:Name="colors"> <GradientStop x:Name="col1" Color="Black" Offset="0" /> <GradientStop x:Name="col2" Color="White" Offset="1" /> </LinearGradientBrush> </Rectangle.Fill> </Rectangle>

This will add a black and while linear gradient fill to the rectangle. The design view of the page should now look similar to the following image:

You've successfully created a WPF application and customized the Rectangle control. In the next step you'll add and customize C1ColorPicker controls.
