Then we need to update the CreditRatingService.csproj file to complete gRPC contract configuration. > dotnet new grpc -o ShoeSizeConversionService NET Core 3+ version installed in your computer to be able to create this service. We'll create a simple gRPC service that returns the US shoe size for an EU size.

NET Core framework 3+ includes tooling and native support for gRPC. It can be a good idea to replace HTTP APIs with gRPC to provide low latency and high throughput communication in some services where efficiency is critical. You can use both HTTP APIs and gRPC in different use-cases. HTTP APIs requests are sent as text (mostly JSON) and can be read and created by humans while gRPC messages are encoded with Protobuf by default which is in binary format and not human readable. gRPC heavily uses HTTP/2 features, and no browser provides the level of control required over web requests to support a gRPC client. gRPC isn't fully supported in the browser it's not possible to directly call a gRPC service from a browser today. However it's easy to understand and use HTTP APIs over gRPC, and there aren't too many restrictions about data contracts or browsers. Combining gRPC and HTTP/2, performance dramatically increases. HTTP/2 supports full-duplex, or bidirectional communication, where both client and server and can communicate at the same time, which is not possible in HTTP APIs. While HTTP APIs use HTTP 1.1, gRPC uses HTTP/2 that makes gRPC faster using less memory. GRPC clients and servers can run and talk to each other in a variety of environments (source: grpc.io). Reduces network usage with Protobuf binary serialization.Supports client, server, and bi-directional streaming calls with HTTP/2 based transport.Great tooling for testing, inspection, and modification.

You can see the full code of this service in this Github repository. In this post, I'll share some details about the gRPC framework, and then there will be a short comparison between gRPC and REST-based HTTP APIs in the end, you will find a simple gRPC service example on.
