Tutorial Structure

This tutorial is organized in the following manner:

• Define the Data Model and Set the Initial Data

  This section explains how to implement classes that define the foundation of your application’s business model and its associated database structure.

• Add Actions (Menu Commands)

  This section explains how to create custom commands in your application.

• Customize Navigation Between Views

  This section explains how to customize the navigation control.

Connection String

This tutorial uses Microsoft’s SQL Server as its target database management system (DBMS). As you may already know, XAF supports multiple database management systems (see the list here). If you’d like to use a different DBMS, be sure to specify the appropriate connection string.

XAF apps create a database with a name that matches the name used for the solution itself. To change names, edit the connection string in the application configuration file (appsettings.json).
