How to use Prism Region in WPF?

Step 1: Install Prism.Core,Prism.DryIoc (You can use any IOC like Prism.Unity),Prism.Wpf.
Step 2: Add the prism namespace to MainWindow.xaml  like below
                          xmlns:prism="http://prismlibrary.com/"
Step 3: Add ContentControl  to MainWindow  and initilize the RegionName
<Grid>
        <ContentControl prism:RegionManager.RegionName="MainRegion"/>
    </Grid>
Step 4: Implement IModule
 class MainModule : IModule
    {
        public void OnInitialized(IContainerProvider containerProvider)
        {
           var region= containerProvider.Resolve<IRegionManager>();
            region.RegisterViewWithRegion("MainRegion", typeof(TabView));
           //TabView is the view  or UserControl which will inject to Region
        }

        public void RegisterTypes(IContainerRegistry containerRegistry)
        {
         
        }
    }
Step 5: App class should inherit from PrismApplication
        Step 5.1: Modify App.xaml 
                          Add the prism namespace to App.xaml  like below
                          xmlns:prism="http://prismlibrary.com/"
        Step 5.2: Replace Application with prism:PrismApplication

          <prism:PrismApplication x:Class="WpfWithPrism.App"

             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

             xmlns:local="clr-namespace:WpfWithPrism"

             xmlns:prism="http://prismlibrary.com/">

      <prism:PrismApplication.Resources>

     

      </prism:PrismApplication.Resources>

     </prism:PrismApplication>

        Step 5.3: override CreateShell, RegisterTypes, ConfigureModuleCatalog Methods in                                           App.xaml.cs file like below.

 public partial class App : PrismApplication
    {
        protected override Window CreateShell()
        {
            return Container.Resolve<MainWindow>();//MainWindow is startup window
        }
        protected override void RegisterTypes(IContainerRegistry containerRegistry)
        {
         
        }
        protected override void ConfigureModuleCatalog(IModuleCatalog moduleCatalog)
        {
            base.ConfigureModuleCatalog(moduleCatalog);
            moduleCatalog.AddModule<MainModule>();
        }
    }
