Remarks

The System Module comprises four assemblies:

• DevExpress.ExpressApp.v22.1.dll

  Contains base classes and services that are used by both the DevExpress.ExpressApp.Win and DevExpress.ExpressApp.Web assemblies.

  This assembly represents a module, since it contains the SystemModule class - a descendant of the ModuleBase class.

• DevExpress.ExpressApp.Win.v22.1.dll

  Contains classes that are required in Windows Forms applications only.

  This assembly represents a module, since it contains the SystemWindowsFormsModule class - a descendant of the ModuleBase class.

• DevExpress.ExpressApp.Web.v22.1.dll

  Contains classes that are required in ASP.NET Web Forms applications only.

  This assembly represents a module, since it contains the SystemAspNetModule class - a descendant of the ModuleBase class.

The SystemModule class exposes properties whose values determine the behavior of system functionality. To set these properties, select the SystemModule component in the Application Designer‘s Modules section, and use the Properties window.
