Remarks

Note

For more information about the default error processing mechanism in XAF ASP.NET Core Blazor applications, refer to the following topic: Error Handling in ASP.NET Core Blazor.

Override the ExceptionService.HandleException(Exception) method in the class descendant to wrap an exception in a user-friendly exception.

Override the ExceptionService.ShouldHandleException(Exception) method in the class descendant to determine how you want to process exceptions.

The following example displays a user-friendly exception message in your XAF Blazor UI application:

Add a controller:
Add a MyTestExceptionService service and override the HandleException method:
Register the MyTestExceptionService service in the MySolution.Blazor.Server\Startup.cs file:
Run the application and click the Test Action button. The user-friendly exception is displayed within a toast notification.
