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 PrismAppl
