XAF features the Solution Wizard, which allows you to create a new application in a few steps. The wizard allows you to:

The wizard generates a solution according to the specified settings.

The Solution Wizard is available when you add a new project.

  1. In the Add a new project dialog, find the DevExpress v21.1 XAF Template Gallery and click Next.

  2. Configure your new project and click Create. The Template Gallery opens. In the Template Gallery, select a target framework (.NET 5 or .NET Framework), a XAF solution, and a programming language (C# or VB.NET). Click Run Wizard.

Tip

You can also run the Solution Wizard from the DevExpress Template Gallery. To find the wizard, choose XAF in the Platform combo box.

Step 1 – Choose the Target Platforms

In this step, you can select:

  • For the .NET Framework solution: Desktop (Windows Forms), Web (ASP.NET Web Forms), or multiple applications at once.
  • For the .NET 5+ solution: Desktop (Windows Forms), Web (ASP.NET Core Blazor), or multiple applications at once.

The wizard will add the required platform-specific application and module projects.

Step 2 – Choose the ORM

In this step, you can choose your data model type.

SolutionWizard_Step2

The wizard will add code that registers an appropriate Object Space Provider (see XafApplication.ObjectSpaceProvider). If you choose Entity Framework Code First, the wizard will generate the DbContext class code.

Step 3 – Enable the Security System and Choose the Authentication Type

In this step, you can enable the Security System and select the authentication type.

SolutionWizard_Step3.1

If you selected Windows and eXpress Persistent Objects in the previous steps, you can also choose the client-side security mode or set up the middle-tier security.

SolutionWizard_Step3.2

If you add an ASP.NET Core Blazor UI project in the first step, the wizard suggests you the following security options:

The wizard will add code that configures the Security System and populates the data model with the entities required to persist Security System data (users, roles and permissions). If you choose Standard authentication, it will also add code that creates the “Admin” user with an empty password to the Updater.cs (Updater.vb) file. If you choose Active Directory authentication, a similar code will be added, but the user name will be taken from your current Windows account.

With the Security System enabled, the wizard also adds the code demonstrated in the How to: Store the Application Model Differences in the Database topic. This code configures the Database Model Difference Storage in both WinForms and ASP.NET Web Forms modules.

Step 4 – Choose Additional Modules

In this last step, you can choose the XAF additional modules to include.

SolutionWizard_Step4

The wizard will register the selected modules and add the entities required by these modules to the data model.

The following image demonstrates the generated solution.

Note

The wizard attempts to detect your installed SQL server and changes the connection string accordingly. Supported servers are Microsoft SQL Server (including the Express and LocalDB editions). To use another database system (PostgreSQL, MySQL, Oracle, SQLite, Firebird, etc.), change the ConnectionString argument in the App.config and Web.config files of the WinForms/ASP.NET Web Forms application projects. Refer to the Connect an XAF Application to a Database Provider topic for details about connecting to different database systems.

Add a Project to an Existing XAF Solution

You can also run the Solution Wizard for an existing solution to create additional XAF projects. Right-click the solution in the Solution Explorer, choose Add | New Project… and select DevExpress v21.1 XAF Template Gallery and click Next. In the Template Gallery, select the newly added project settings and click Run Wizard. The image below shows the Wizard’s start page in this case.
