In .NET 6 there is component called ErrorBoundary. Simple example: <ErrorBoundary> @Body </ErrorBoundary> Advanced Example: <ErrorBoundary> <ChildContent> @Body </ChildContent> <ErrorContent Context=”ex”> @{ OnError(@ex); } @*calls custom handler*@ <p>@ex.Message</p> @*prints exeption on page*@ </ErrorContent> </ErrorBoundary> For the global exception handling I see this as an option: Create CustomErrorBoundary (inherit the ErrorBoundary) and override the OnErrorAsync(Exception exception). … Read more

The reason that the UnhandledException event on the current AppDomain does not fire is how services are executed. User sends a Start command from the Windows Service Control Manager (SCM). The command is received by the framework’s ServiceBase implementation and dispatched to the OnStart method. The OnStart method is called. Any exception which is thrown … Read more
You haven’t run manage.py makemigrations customuser to create the migrations for your CustomUser app. Also, you haven’t run any of the existing migrations – you should do manage.py migrate.
What you’re describing is not the defined behavior of BackgroundWorker. You’re doing something wrong, I suspect. Here’s a little sample that proves BackgroundWorker eats exceptions in DoWork, and makes them available to you in RunWorkerCompleted: var worker = new BackgroundWorker(); worker.DoWork += (sender, e) => { throw new InvalidOperationException(“oh shiznit!”); }; worker.RunWorkerCompleted += (sender, e) … Read more
Take a look at the example from the ThreadException documentation: public static void Main(string[] args) { // Add the event handler for handling UI thread exceptions to the event. Application.ThreadException += new ThreadExceptionEventHandler(ErrorHandlerForm.Form1_UIThreadException); // Set the unhandled exception mode to force all Windows Forms errors // to go through our handler. Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException); // Add the … Read more
There’s a new window called “Exception Settings” that appears in the lower right pane by default when you begin debugging. It has all of the options you would expect. You can bring it up with CTRL+ALT+E This allows you to cherry-pick which exceptions cause a break in the debugger. The key, though, is that you … Read more
This is now possible with WebAPI 2.1 (see the What’s New): Create one or more implementations of IExceptionLogger. For example: public class TraceExceptionLogger : ExceptionLogger { public override void Log(ExceptionLoggerContext context) { Trace.TraceError(context.ExceptionContext.Exception.ToString()); } } Then register with your application’s HttpConfiguration, inside a config callback like so: config.Services.Add(typeof(IExceptionLogger), new TraceExceptionLogger()); or directly: GlobalConfiguration.Configuration.Services.Add(typeof(IExceptionLogger), new TraceExceptionLogger());
In Java, as you may know, exceptions can be categorized into two: One that needs the throws clause or must be handled if you don’t specify one and another one that doesn’t. Now, see the following figure: In Java, you can throw anything that extends the Throwable class. However, you don’t need to specify a … Read more
