Property Value

Type	Description
Version	A Version object that represents the current module’s assembly version.

Remarks

This property is used when the built-in Updater compares the module’s actual version with the module version in the database. If the actual module version is lower than the version in the database, an exception is raised; otherwise, the Updater updates the module version in the database to the actual one. This process is performed each time the application runs in the debugging mode, because each application has the following XafApplication.DatabaseVersionMismatch event handler, by default:

C#

public partial class MySolutionWindowsFormsApplication : WinApplication {
   private static void MySolutionWindowsFormsApplication_DatabaseVersionMismatch(object sender, 
         DatabaseVersionMismatchEventArgs e) {
      if(System.Diagnostics.Debugger.IsAttached) {
         e.Updater.Update();
         e.Handled = true;
      }
   }
partial class MySolutionWindowsFormsApplication {
   //...
   private void InitializeComponent() {
      //...
      this.DatabaseVersionMismatch += this.MySolutionWindowsFormsApplication_DatabaseVersionMismatch;
      // ...
   }
   // ...
}

VB.NET

Public Partial Class MySolutionWindowsFormsApplication
      Inherits WinApplication
   Private Shared Sub MySolutionWindowsFormsApplication_DatabaseVersionMismatch( _
   ByVal sender As Object, _
   ByVal e As DatabaseVersionMismatchEventArgs) Handles MyBase.DatabaseVersionMismatch
      If System.Diagnostics.Debugger.IsAttached Then
         e.Updater.Update()
         e.Handled = True
      End If
   End Sub
Public Partial Class MySolutionWindowsFormsApplication
   '...
   Private Sub InitializeComponent()
      '...
      AddHandler DatabaseVersionMismatch, _
      AddressOf MySolutionWindowsFormsApplication_DatabaseVersionMismatch
      ' ...
   End Sub
   ' ...
End Class

For more information on updating database versions, refer to the Update Application and Database Versions using the ModuleInfo Table topic. If you need to implement your own Updater, use the Version property to get the actual module version.
