gRPC using .NET core notes

-gRPC is a framework for RPC calls
-helps to execute a remote method somewhere in the n/w
-born out of goog, gRPC is a open source variant
-MS .NET team is partnering with goog folks and CNCF to make gRPC performant on .NET core
-it has 4 low level primitives
1) Unity calls (single client req, single server response)
2) Client streaming (multiple client req, single server response)
3) Server streaming (single cli-req, multiple server response)
4) full duplex
-it works on top of http2 as a transporter
-gRPC-web preview exist today for browser support but gRPC is pretty for svc-svc communication
-it needs a protobuf file defining the message types used by the gRPC- contract equivalent

• $ dotnet new grpc -o GrpcServer to generate a sample proj in .NET core
• building the project generates the code file for most of the languages based on proto contract file
• protobuf -binary seralization format, https/2, multiplexing, streaming, more efficient, quality of generated code is better for any languages makes gRPC better than REST API’s.
• REST API’s required path, verb used etc but in gRPC not required
• – one can expose them as HTTP endpoints or gRPC endpoints – option is there
• gRPC ->
• Get started with a gRPC service
• Introduction to gRPC on .NET Core

.NET in 2020 (Build recap)

Announcements from //Build 2020 event, [Video1]  [Video2]

1. .NET 5 is a path forward (merging .NET core and mono/xamarin), .NET 6 and on.
2. C# 9 and F#5 released; It will be part of .NET 5
3. .NET 5 will have lesser container img size
4. Win Form designer support for .NET Core; you can design winforms using .NET core
5. Blazor (Web Assembly) – Ready for production. Now, .NET runs on our browser
6. .NET (MAUI) – Multi platform App UI -> build cross-platform Native UI; build once, deploy to multiple devices
7. VS 2019 enhancements and mac support

Happy learning !
