In this post, you will learn about gRPC and protocol buffers, how to build gRPC services in .NET Core/5 using C## and also how to create gRPC clients. gRPC is a high-performance RPC framework with pluggable authentication and load balancing features.

gRPC is a high-performance RPC framework that efficiently allows service-to-service communication within and across data centers. It also supports connecting mobile devices and browser clients to backend services. It was implemented in Google and later open-sourced, and it’s currently a Cloud Native Computing Foundation (CNCF) incubation project. Its features include:

• Bi-directional streaming
• Powerful binary serialization
• Pluggable authentication, load balancing and health check

If you adopt microservice architecture in your organization, gRPC would most likely give a performance boost for the communication between your microservices.

In this post, I’ll show you how to create a gRPC service using .NET Core 3.1 (or later). I will break down some important foundational concepts of gRPC and also include steps for doing those for Mac and VS Code users.

As a prerequisite, I expect some familiarity with C#, ASP.NET Core and either Visual Studio or VS Code.
