Creating multiple Layers Application in Visual Studio

Let’s build an ASP.NET Core MVC application with a clean architecture, separating concerns into multiple layers:

• Business Logic Layer (BLL)
• Data Access Layer (DAL)
• Web API Layer
• Presentation Layer (MVC)
• Test Layer (Unit Testing)

The project will be organized as follows:

Project Structure

• MyApp.Business (Business Logic Layer - BLL)
• MyApp.Data (Data Access Layer - DAL)
• MyApp.WebAPI (Web API Layer)
• MyApp.Web (Presentation Layer - MVC)
• MyApp.Tests (Test Layer)
