Doing so creates a Dockerfile that containerizes your. BufferKBytes - This is the desired size of the internal buffer. FileFilter - This is the file mask of files to monitor. When creating a long-running service from the Worker template in Visual Studio, you can opt in to Docker support. WatchesFilters - This is a flags-based enumerator that allows the programmer to specify which basic events to handle (Changed, Created, Deleted, Renamed, All). NET workloads, containers are a viable option. NuGet packageĪn app based on the Worker template uses the SDK and has an explicit package reference to the package. ![]() The Worker template relies on the following project file Sdk: įor more information, see. ![]() In the template implementation, the ExecuteAsync loops once per second, logging the current date and time until the process is signaled to cancel. The BackgroundService is an abstract class and requires the subclass to implement BackgroundService.ExecuteAsync(CancellationToken). The preceding Worker class is a subclass of BackgroundService, which implements IHostedService. _logger.LogInformation("Worker running at: ", DateTimeOffset.Now) While (!stoppingToken.IsCancellationRequested) Protected override async Task ExecuteAsync(CancellationToken stoppingToken) Public sealed class Worker : BackgroundService The template consists of a Program and Worker class.

Many terms are mistakenly used synonymously. If you're using Visual Studio, the template is hidden until the optional ASP.NET and web development workload is installed. Note that in some scenarios, like the example used below, the first event will be the start of the file writing and the. NET SDK, you could create a new worker by using the dotnet new worker command. FileSystemWatcher is a great little class to take the hassle out of monitoring activity in folders and files but, through no real fault of its own, it can behave unpredictably, firing multiple events for a single action. NET SDK also installs the and the worker template.
