One of the flaw of this approach is that it can't do all of the expected Patch operations. In Second approach our method take a DTO, look for the properties that are populated. Still, it's minimal. Start Save The Product entity class represents the data for a product in the application, it contains a minimal set of properties (just Id and Name) for testing the minimal API. There is option to select authentication type. Since we want to focus on Minimal APIs our implementation is simple and it is missing proper request model validations or using mapping with AutoMapper. In Minimal API there won't be any controller or action methods. To perform CRUD operations, we developed a generic synchronized repository pattern. The problem here is that the JsonOptions type is pulled from the Microsoft.AspNetCore.Mvc namespace while .NET 6 minimal APIs are documented to use. Entity Framework 4 - Entity Dependency Injection. Okay, your project will be created and should have this structure: Repository pattern is a way to create better code architecture. A DI framework allows you to inject the dependencies, and in our web application to be precise, it allows you to inject the Data Layer contracts in Business Layer and the Business Layer contracts in presentation without having to create concrete instances of the implementation. We can build Web API and Entity framework with code first or database first approach, however, it is hard to do so in the real working environment with ASP.NET Core Web API calling stored procedure. Install-package Microsoft.EntityFrameworkCore We'd use Entity Framework Core as the mapping layer between SQLite db and our project. Start Save Prerequisites Familiarity with .NET 6 A basic understanding of what an API is This module is part of these learning paths In short focus on the system components that manage authentication and leave the user management to the application. It was introduced in Asp.Net 6, and they are ideal for microservices that can be finished with minimum files and features.
