How to implement solution with custom handling handling in asp.net core 6 when using middleware
This might be a silly question, but I'm experiencing an scenario with my custom exception handling middleware in an ASP.NET Core 6 application. I've set up my middleware to catch exceptions globally, but it seems to only capture exceptions thrown from within controllers and not from other parts of the application, such as background tasks. I have the following middleware implementation: ```csharp public class ExceptionHandlingMiddleware { private readonly RequestDelegate _next; public ExceptionHandlingMiddleware(RequestDelegate next) { _next = next; } public async Task InvokeAsync(HttpContext context) { try { await _next(context); } catch (Exception ex) { await HandleExceptionAsync(context, ex); } } private Task HandleExceptionAsync(HttpContext context, Exception ex) { context.Response.StatusCode = (int)HttpStatusCode.InternalServerError; return context.Response.WriteAsync("Internal Server behavior: " + ex.Message); } } ``` I've registered this middleware in the `Configure` method of `Startup.cs`: ```csharp public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { app.UseMiddleware<ExceptionHandlingMiddleware>(); app.UseRouting(); app.UseEndpoints(endpoints => { endpoints.MapControllers(); }); } ``` In my background service, I'm throwing an exception like this: ```csharp public class MyBackgroundService : BackgroundService { protected override async Task ExecuteAsync(CancellationToken stoppingToken) { throw new InvalidOperationException("This is a test exception"); } } ``` When the exception is thrown in the background service, it doesn't get caught by my global exception handler. Instead, it crashes the service, and I see an unhandled exception message in the console. I've tried wrapping the code in `try-catch` blocks within the background service, which works, but I would prefer to handle exceptions globally if possible. Is there a way to ensure that my middleware catches exceptions thrown from background services, or do I need to implement a different approach? Any guidance or best practices would be appreciated! This is part of a larger CLI tool I'm building.
