Description

We've added a new CollectionView2 handler for MacCatalyst/iOS.

We can do the same with Windows now that there is a newer API available to use for virtualized lists of things.

@Foda has done some spikes on this, and the newer API is used already in Maui.VirtualListView

Public API Changes

CollectionView2Handler

Intended Use-Case

A newer implementation of the handler which performs better.

Current work

#if WINDOWS
        builder.ConfigureMauiHandlers(handlers =>
        {
            handlers.AddHandler<Microsoft.Maui.Controls.CollectionView, Microsoft.Maui.Controls.Handlers.Items2.CollectionViewHandler2>();
        });
#endif
