  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.
