        Loaded="Window_Loaded">
    <DataGrid x:Name="dgEmployee"
              Width="221"

              ColumnWidth="*">
        <DataGrid.Columns>
            <DataGridTextColumn x:Name="dgrEmpId"
                                Binding="{Binding EmpId}"
                                Header="EmpId"
                                IsReadOnly="True" />
            <DataGridTextColumn x:Name="dgrFirstName"
                                Binding="{Binding FirstName}"
                                Header="FirstName"
                                IsReadOnly="True" />
            <DataGridTextColumn x:Name="dgrLastName"
                                Binding="{Binding LastName}"
                                Header="LastName"
                                IsReadOnly="True" />
        </DataGrid.Columns>
    </DataGrid>
</Window>

MainWindow.xaml.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace SelectData_WPF_EFApp
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            dgEmployee.ItemsSource = objEmployeeEntities.Employees.ToList();
        }

        EmployeeDBEntities objEmployeeEntities = new EmployeeDBEntities();
    }
}

The output of the application is as in Figure 8.
