For .NET Core 3.0, we’re shipping a brand new namespace called System.Text.Json with support for a reader/writer, a document object model (DOM), and a serializer. In this blog post, I’m telling you why we built it, how it works, and how you can try it. 

Here’s the list of what’s new in this preview:

• New Razor features: @attribute, @code, @key, @namespace, markup in @functions
• Blazor directive attributes
• Authentication & authorization support for Blazor apps
• Static assets in Razor class libraries
• Json.NET no longer referenced in project templates
• Certificate and Kerberos Authentication
• SignalR Auto-reconnect
• Managed gRPC Client
• gRPC Client Factory
• gRPC Interceptors 

Today, we are announcing .NET Core 3.0 Preview 6. It includes updates for compiling assemblies for improved startup, optimizing applications for size with linker and EventPipe improvements. We’ve also released new Docker images for Alpine on ARM64.
