The difference between Registertype and registerinstance in UnityContainer

Both of these registration methods are used in the application, the following is their own understanding

RegisterInstance registering a single case mode

1             _container. Registerinstance<inavigationservice>(navigationservice); 2             _container. Registerinstance<isessionstateservice>(sessionstateservice); 3             _container. Registerinstance<ieventaggregator>(eventaggregator); 4             _container. Registerinstance<iresourceloader> ( new Resourceloaderadapter (new Resourceloader ()));         

Registered objects that have been instantiated, each call to resolve to remove the registered object is a unique singleton

Registertype Registration Type

1             _container. Registertype<iproductcatalogrepository, productcatalogrepository>(); 2             _container. Registertype<ishoppingcartrepository, shoppingcartrepository>(); 3             _container. Registertype<icheckoutdatarepository, checkoutdatarepository>(); 4             _container. Registertype<iorderrepository, orderrepository> ();    

Only when the resolve is called, the registered object is instantiated, multiple calls are made, several objects are instantiated repeatedly

Can be added type ContainerControlledLifetimeManager also registered as a singleton

1             _container. Registertype<iproductcatalogservice, productcatalogserviceproxy> (new  ContainerControlledLifetimeManager ()); 2             _container. Registertype<iorderservice, orderserviceproxy> (new  ContainerControlledLifetimeManager ()); 3             _container. Registertype<ishoppingcartservice, shoppingcartserviceproxy> (new ContainerControlledLifetimeManager ());    

1

            _container. Registertype<iproductcatalogrepository, productcatalogrepository> (new ContainerControlledLifetimeManager ());

2

            _container. Registerinstance<iproductcatalogrepository> (new

1 and 2, the individual understanding of the time is different, 1 in the first call through resolve, 2 at the time of registration to instantiate.
