Remarks

The XafApplication class contains methods to create Controllers, Views, Object Space (see BaseObjectSpace), and other XAF elements. Its properties specify application name and title, configuration string, provide access to the Application Model, modules and the strategy that manages View visibility. You can customize many built-in mechanisms to manage your application. For this purpose, use XafApplication‘s events.

XAF creates and initializes a XafApplication descendant as follows:

Platform	Created and Initialized	File
ASP.NET Core Blazor	When `IXafApplicationProvider.GetApplication()` is called for the first time (usually when XAF initializes the page).	Startup.cs
Windows Forms	In the `Main` method.	Program.cs
ASP.NET Web Forms	When a session starts.	Global.asax.cs
Application Server	In the `ApplicationServerService` constructor.	ApplicationServerService.cs
Backend Web API Service / REST API	Only during initialization.	Startup.cs

Note

XafApplication is not available in Web API Service endpoints. XAF creates it on service initialization only for compatibility check and localization services setup.

To configure your application, use Application Builder.
