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. 

As with every .NET release, Microsoft improves the performance of the runtime and guess what: This release is no exception to this. In this blog post, I want to go through some of the improvements made so far (.NET 8 preview 3).

In .NET 8 Preview 3, this can be changed to dump the /bin and /obj artifacts into an .artifacts directory instead of the source root. 

In version 8, this dependency is removed, and developers will be able to pick from IdentityServer or any other number of OpenId Connect and OAuth 2.0 implementations.
Ostensibly, these changes will make it easier to create and ship "simple" auth systems that do things like use social logins - and I look forward to trying them out as they become available.
 

Preview 3 of .NET 8 includes a new project templates to create an API with a TODO service instead of the weather forecast . Looking into the generated code of this template, there are a lot more changes going on such as a slim builder and using a JSON source generator which helps when using AOT to create native .NET binaries. This article looks into the changes coming. 

Here’s a summary of what’s new in this preview release:

• ASP.NET Core support for native AOT
• Server-side rendering with Blazor
• Render Razor components outside of ASP.NET Core
• Sections support in Blazor
• Monitor Blazor Server circuit activity
• SIMD enabled by default for Blazor WebAssembly apps
• Request timeouts
• Short circuit routes 

.NET 8 Preview 3 is now available. It includes changes to build paths, workloads, Microsoft.Extensions, and containers. It also includes performance improvements in the JIT, for Arm64, and dynamic PGO. If you missed the March preview, you may want to read the Preview 2 post.
