Three-layered ASP.NET Core web application (sample)

The source code is available in the src folder.

• You need a Microsoft SQL Server and the sample database. You can edit the connection string in Webshop.Web/appsettings.json.
• Web application: open the solution in Visual Studio, right-click project Webshop.Web and choose "Set as Startup Project", then F5 to build and start; it will also open a browser to http://localhost:5000.
• REST API: start the application and use Postman to query http://localhost:5000/api/customers.
• There is a sample unit test that you can run with Visual Studio too.

Structure of the application

The sample is a standard three-layered web app:

• Webshop.Web: ASP.NET Core web application; this is the entry point that hosts the web server
  • Contains an MVC Razor Pages web app
  • And also serves REST queries
• Webshop.BL: the business layer for managing the business workflows
• Webshop.DAL: the data access layer
  • Uses Enity Framework Core for data access
  • But wraps all operations using the repository design pattern
• Webshop.Test: contains unit tests
