- Use WebSockets over HTTP/2 connections.
- Create streams and datagrams over HTTP/3 with experimental support for WebTransport.
Minimal APIs
- Use endpoint filters to run cross-cutting code before or after a route handler.
- Return strongly typed results from minimal APIs.
- Organize route groups of endpoints with a common prefix
gRPC
- Expand the reach of your gRPC services by also exposing them as JSON-based APIs
- Use experimental support for generating OpenAPI specs for your gRPC JSON transcoded services.

- Intercept location changing events to create custom user experiences when navigating.
- Run async logic after data binding and independently control how data binding gets and sets the data.
- Create dynamic authentication requests at runtime with custom parameters to handle advanced authentication scenarios in Blazor WebAssembly apps.
