Resources:

It provide a simple way to reuse commonly defined objects and values. If we are defining the resource then we can use that resource a number of times. (Just like applying themes and css to web pages).

Two Types of Resource:

                    1. Static Resource.
                    2. Dynamic Resource.

STATIC RESOURCE:

StaticResources are resolved at compile time. Use StaticResources when it's clear that you don't need your resource re-evaluated when fetching it static resources perform better than dynamic resources

DYNAMIC RESOURCE:

DynamicResources are resolved at runtime. Use DynamicResources when the value of the resource could change during the lifetime of the Application.

Example for Static Resource:

In my WPF application page I have one textbox and two ellipses. In Window.Resources I defined the SolidColorBrush and the Style properties.

Code Sample:

            <Window.Resources>
            <SolidColorBrush x:Key="brush" Color="Green"></SolidColorBrush>
            <SolidColorBrush x:Key="forbuttoncolor" Color="CadetBlue"></SolidColorBrush>
            <Style TargetType="Border" x:Key="background">
            <Setter Property="Background" Value="Orange"></Setter>
            </Style>
            <Style TargetType="TextBox" x:Key="TitleText">
            <Setter Property="Background" Value="White"/>
            <Setter Property="DockPanel.Dock" Value="Top"/>
            <Setter Property="FontSize" Value="14"/>
            <Setter Property="Foreground" Value="#4E87D4"/>
            <Setter Property="FontFamily" Value="Tahoma"/>
            <Setter Property="Margin" Value="50,50,50,0"/>
            <Setter Property="Width" Value="300"></Setter>
            </Style>
            </Window.Resources>

In above code you can observe x: Key attribute. x: Key uniquely identifies elements that are created and referenced in a XAML-defined dictionary.

Here I'm using above resources. Have a look at below code.
Syntax is :{ StaticResource x:keyName}

              <Grid>
             <StackPanel>
             <Border Style="{StaticResource background}">
             <DockPanel Height="300" Width="500">
             <TextBox Style="{StaticResource TitleText}" Height="28" Width="150"> </TextBox>
             <Ellipse DockPanel.Dock="Left" HorizontalAlignment="Left" Height="73" Fill="{StaticResource  
                brush}" Width="169"></Ellipse>
             <Ellipse DockPanel.Dock="Right" HorizontalAlignment="Right" Width="149" Height="73" Fill="   
               {StaticResource forbuttoncolor}"></Ellipse>
             </DockPanel>
             </Border>
