Create normal App.config file and there is a <connectionStrings/> section in it you could use.

Then in code you use ConfigurationManager class to get the connection string you want.

Add new item -> Application Configuration file   (this is app.config)

Put:
<?xml version="1.0" encoding="utf-8" ?> 
<configuration> 
  <connectionStrings> 
    <add name="myConnection" connectionString="Server=(local);Database=Test;Integrated Security=True"/> 
     
  </connectionStrings> 
</configuration> 

In there.

Create Window1.xaml:
<Window x:Class="WpfApplication4.Window1" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    Title="Window1" Height="300" Width="300"
    <Grid> 
        <TextBlock x:Name="txtConn" /> 
    </Grid> 
</Window> 
 

in Window1.xaml.cs:

using System.Configuration; 
using System.Windows; 
namespace WpfApplication4 
    /// <summary> 
    /// Interaction logic for Window1.xaml 
    /// </summary> 
    public partial class Window1 : Window 
    { 
        public Window1() 
        { 
            InitializeComponent(); 
            txtConn.Text = ConfigurationManager.ConnectionStrings["myConnection"].ConnectionString; 
        } 
    } 
 
Done.

This is the way to go. You dont want to embed your connection string in XAML, because you wont be able to change it during runtime if DB has changed etc.
