Step 1: Create a WPF application and add new item Resource Directory(WPF) and named it Style.xaml

Step 2: Update the MainWindow.xaml as follows.

<Window x:Class="LabelControl.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="274" Width="470">

    <Window.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Style.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Window.Resources>
 
    <WrapPanel>
        <Label Content="Hello World!" Style="{StaticResource roundLabel}"/>
        <Label Content="Hello World!" Style="{StaticResource styleTextLabel}"/>
        <Label Content="Hello World!" Style="{StaticResource styleBorderTextLabel}"/>
        <Label Content="Hello World!" Style="{StaticResource styleImageBrushLabel}"/>
    </WrapPanel>
</Window>
