Introduction
Validation is a very important feature in applications but in ASP.NET Core 3.1 and gRPC it’s a bit complicated…. Proto3 doesn’t provide any validation with its syntax and Microsoft gaves us the habit to use DataAnnotation in ASP.NET and ASP.NET Core, unfortunaltey this feature is not available neither in gRPC. So a solution is required to fix that limitation, in this article I will show you how to use packages I have designed : Calzolari.Grpc.AspNetCore.Validation and Calzolari.Grpc.Net.Client.Validation. The full documentation is available here: https://github.com/AnthonyGiretti/grpc-aspnetcore-validator (forked and improved with more features from https://github.com/enif-lee/grpc-dotnet-validator).
