NET Core 3.0, you can leverage the grpc-dotnet library, entirely written in managed code and well-integrated with the. You also didn't have any project template helping you to quickly set up your application with gRPC support. It wasn't playing very well with Kestrel and other managed code libraries like HttpClient.

It basically is a C# wrapper around the gRPC Core library written in C. NET Core 3.0 release, you could use gRPC in your C# applications by using the Grpc.Core library. So, both technologies will continue to coexist in the next years. In short, Web APIs and gRPC use different models for communication and have different use-cases. Finally, Web APIs support browsers, while gRPC don't. The interaction model in Web APIs is client-server, while gRPC supports multiple models: from client-server to bidirectional streaming. Also, data exchanged by Web APIs are usually textual, human-readable (typically JSON), while gRPC uses a compact binary format. In addition, Web APIs are based on the HTTP protocol, while gRPC uses HTTP/2. Standard Web APIs are based on a resource-oriented approach, which is a model where a client requests a resource representation and applies simple CRUD operations on these resources.

The gRPC framework proposes the RPC model, which is a model where a client invokes a remote procedure that will be executed on the server. The Web APIs, especially if inspired by the REST architecture, rely on a different programming model. There are a couple of factors to take into account. Since gRPC is so efficient and handy, why has it not replaced the well-known HTTP Web API technology? The following diagram summarizes the overall architecture of a basic gRPC-based system:

Bidirectional streaming RPC: in this case, the client and the server exchange messages in both directions.

Client streaming RPC: this is the case where the client sends a sequence of messages and receives a single response from the server.

Server streaming RPC: in this scenario, the client sends a request message to the server and receives a sequence of responses.

In this case, the client sends a request message to the server and receives a response.

Unary RPC: this is the simplest form of RPC.

This aspect simplifies the creation of services interaction and, together with the high performance, makes gRPC the ideal framework to create microservices.Īlso, gRPC comes with four different types of RPC: Once you define a contract with Protobuf, this contract can be used by each service to automatically generate the code that sets up the communication infrastructure.

The gRPC framework allows developers to create services that can communicate with each other efficiently and independently from their preferred programming language. Many tools for the most common programming languages are available to translate these Protobuf interfaces into code. Protocol Buffers, also known as Protobuf, allow you to define the interface to be used in service to service communication independently from the programming language. It also relies on the Protocol Buffers language to define service contracts. It is focused on high performance and uses the HTTP/2 protocol to transport binary messages. Initially designed by Google, it is now an open-source project promoting the Remote Procedure Call (RPC) model for communication between services. GRPC is a framework to efficiently connect services and build distributed systems.

You can find the full code of the final project in this GitHub repository. Throughout the tutorial, you will build a service and a client that will introduce you to the details of using gRPC in C#. NET Core 3.1 to build efficient microservices. TL DR: In this tutorial, you will learn what gRPC is and how you can use it in.
