What’s new?

Here’s a sampling of the great new features and improvements in ASP.NET Core for .NET 7:

• Servers and runtime
  • Rating limiting: Limit the rate of handled requests using flexible endpoint configuration and policies.
  • Output caching: Configure output caching to reduce to more efficiently handle request.
  • Request decompression: Accept requests with compressed content.
  • HTTP/3: Built-in support for HTTP/3, the latest HTTP version based on the new QUIC multiplexed transport protocol.
  • WebSockets over HTTP/2: Use WebSockets over HTTP/2 connections.
  • WebTransport (experimental): Create streams and data grams over HTTP/3 with experimental support for WebTransport.
• Minimal APIs
  • Endpoint filters: Use endpoint filters to run cross-cutting code before or after a route handler.
  • Typed results: Return strongly typed results from minimal APIs.
  • Route groups: Organize groups of endpoints with a common prefix
• gRPC
  • JSON transcoding: Expand the reach of your gRPC services by also exposing them as JSON-based APIs
  • OpenAPI with JSON transcoding (experimenal): Use experimental support for generating OpenAPI specs for your gRPC JSON transcoded services.
  • gRPC health checks: Report and check the health of gRPC server apps.
  • gRPC client AddCallCredentials : Create clients that send authorized requests using bearer tokens.
• SignalR
  • Client results: Return client results to the server in response to requests from the server.
• MVC
  • Nullable view and page models: Nullable page and view models are now supported to improve the experience when using null state checking.
• Blazor
  • Custom elements: Build standard HTML custom elements with Blazor to integrate Blazor components with any JavaScript-based app.
  • Handle location changing events: Intercept location changing events to create custom user experiences when navigating.
  • Bind after/get/set modifiers: Run async logic after data binding and independently control how data binding gets and sets the data.
  • Dynamic authentication requests: Create dynamic authentication requests at runtime with custom parameters to handle advanced authentication scenarios in Blazor WebAssembly apps.
  • Improved JavaScript interop on WebAssembly: Optimize JavaScript interop call when running on WebAssembly using the new [JSImport]/[JSExport] support.
  • WebAssembly SIMD & exception handling: Improve performance with .NET WebAssembly ahead-of-time (AOT) compilation using WebAssembly SIMD and exception handling support. 

gRPC Service with .NET 7
In this video we build a gRPC service with 5 methods: Create, Read (single), List (multiple), Update and Delete. We then employ JSON transcoding (a new feature added in .NET 7) to allow our gRPC service to act as a REST based API. This allows web-based endpoints to consume our service, while at the same time continuing to allow native gRPC clients to consume as well.
