  The "Blazor United" effort is really a collection of features we're adding to Blazor so that you can get the best of server & client based web development. These features include: Server-side rendering, streaming rendering, enhanced navigations & form handling, add client interactivity per page or component, and determining the client render mode at runtime. We've started delivering server-side rendering support for Blazor with .NET 8 Preview 3, which is now available to try out. We plan to deliver the remaining features in upcoming previews. We hope to deliver them all for .NET 8, but we'll see how far we get. 

With .NET 6 previews starting right around the corner, it is time to start getting excited for the new .NET Multi-platform App UI (MAUI) that was announced at BUILD 2020. This year of .NET has a lot of amazing things for client application developers. Let’s review the highlights and set your expectations for the year ahead.
