In C# .NET you can build 3 different kinds of Presentation Layers. List them.

Expert Solution

Three-layer architecture is made of Presentation, Business, and Data access layer. In this article, I will create three-layer architecture with the help of a simple ASP.NET application. You can understand the importance of these three layers with the help of complete article.

-Layers architecture

In the three layers architecture, as you can see, Presentation layer and business layer communicate with each other, and business layer (Controller) and data access layer (Model) communicate with each other.

Presentation Layer

The presentation layer is used to display the data to the users. Your .html or .aspx Pages are presentation layer which shows data to the users. Add one web application project to solution and give the name Presentation layer to it. Add one web page as I did in the below image.

Business Layer

This is the middle layer which communicates with Presentation and data access Layers. Business layer sends a request to Data layer for data and sends data to the presentation layer to display to the end user. In this layer, we write business logic. Now, it is time to create a business layer. Let us add one class library to create a business layer and give the name BusinessLayer to it as I did in the below Image.

Data Access Layer

Data access layer communicates with the database as well as the presentation layer. Presentation layer sends a request to data access layer and data access layer sends a request to the database to get data and returns the data to presentation layer in the form of the object, list, array etc. Now, it is time to create a data access layer by adding one more class library and give name “DataAccess” to it as I have added in the below image.
