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.

Postman Now Supports gRPC 

Support was added in Windows 10 Insider Preview Build 20241, whereas server 2022 is at build 20348. 

.NET Microservices – Full Course, Les Jackson
In this step-by-step tutorial I take you through an introduction on building microservices using .NET. As the name suggests we build everything completely from start to finish –with the full scope of the course outlined in the time-stamp section below. However, at a high-level we’ll cover:

• Building two .NET Microservices using the REST API pattern
• Working with dedicated persistence layers for both services
• Deploying our services to Kubernetes cluster
• Employing the API Gateway pattern to route to our services
• Building Synchronous messaging between services (HTTP & gRPC)
• Building Asynchronous messaging between services using an Event Bus (RabbitMQ)

 

The future of gRPC in C# belongs to grpc-dotnet 

- HTTP.sys requires .NET 5 and Windows 10 Build 19529 or later.
- IIS requires .NET 5 and Windows 10 Build 20241 or later.
