ASP.NET Core 3.0: State of the art
summary
ASP.NET Core 3.0 is essentially 2.2 plus a few shifts: it runs only on .NET Core 3, removes Newtonsoft.Json from the shared framework, ships EF Core as a NuGet package, adds Blazor server components, and changes the pipeline to middleware plus UseRouting/UseEndpoints wiring. The platform exposes six endpoint types (MVC/API controllers merged, POCO controllers, SignalR hubs, gRPC services, worker services). gRPC uses Protocol Buffers over HTTP/2 (binary, faster than JSON). Demo shows a Visual Studio greeter proto → generated greeter base → client call returning “Hello <name>,” working end-to-end.
