.NET Core 3 – what impressed me

This are the things that have impressed me:

• Async Streams ( think in conjunction with about EFCore / SignalR / gRPC / Observables)
•  .NET Default Interface members ( not appliable to classes  – so multiple inheritance is a problem just for interfaces…)
• Deconstruct – see a class from his properties
• Switch  – they improved Switch to work practically in any case scenario
• For Windows Application –  COM support,MSIX
• For any application – Default Files Executable ( about time!),assembly linking( tree-shaking in Javascript idiom),single files executables ( like a jar file,but executable)
• For plugins: Assembly loading improvements and Assembly Unloadability
• gRPC in ASP.NET Core
• SignalR improvements
• Windows Authentication has been extended onto Linux and macOS
• As of ASP.NET Core 3.0,.NET Framework is no longer a supported target framework.
• EFCore : Restricted client evaluation – Explicit loading data from database
• EFCore: Async in loading data
• EFCore : IDBCommandInterceptor for

But there are more improvements( nullable for classes,using syntax,static local functions…)
