![]() ![]() The following sample code gets the deferral, saves it, and releases it when the asynchronous code is complete. Declare the deferral complete after the asynchronous code completes. Save the deferral to a class data member so that it can be accessed from the asynchronous method. Request the deferral in the Run method before calling the asynchronous method. If you don't use a deferral, then the background task process can terminate unexpectedly if the Run method returns before any asynchronous work has run to completion. ![]() If you run any asynchronous code in your background task, then your background task needs to use a deferral.I opened the task scheduler in admin, went to Task Scheduler Library > Microsoft > Office, then disabled. Void ExampleBackgroundTask::Run(IBackgroundTaskInstance^ taskInstance) Looks like it is a Microsoft Office Background Task Handler that keeps popping the CMD up. Virtual void Run(IBackgroundTaskInstance^ taskInstance) Public ref class ExampleBackgroundTask sealed : public IBackgroundTask Using namespace Windows::ApplicationModel::Background Void ExampleBackgroundTask::Run(Windows::ApplicationModel::Background::IBackgroundTaskInstance const& taskInstance) Namespace winrt::Tasks::factory_implementation Void Run(Windows::ApplicationModel::Background::IBackgroundTaskInstance const& taskInstance) Struct ExampleBackgroundTask : ExampleBackgroundTaskT First, add ExampleBackgroundTask.idl, and then build. Public void Run(IBackgroundTaskInstance taskInstance) Public sealed class ExampleBackgroundTask : IBackgroundTask The following sample code shows a very basic starting point for a background task class. The background task class itself-and all other classes in the background task project-need to be public classes that are sealed (or final). The IBackgroundTask.Run method is a required entry point that will be called when the specified event is triggered this method is required in every background task. To the background tasks project, add a new class that implements the IBackgroundTask interface.Under Solution, select Projects and then select the name of your background task project and click Ok. For a C# or C++ app, in your app project, right-click on References and select Add New Reference. Reference the background tasks project from your Universal Windows Platform (UWP) app project.Then select the Windows Runtime Component project type, name the project, and click OK. To do this, right-click on your solution node in the Solution Explorer and select Add > New Project. Create a new project for background tasks and add it to your solution.The following steps show you how to write a new class that implements the IBackgroundTask interface. This code runs when a specific event is triggered by using, for example, SystemTrigger or MaintenanceTrigger. You can run code in the background by writing classes that implement the IBackgroundTask interface. See the Background task sample for an example. This applies for apps using the Windows App SDK, WinUI 3, WPF, or WinForms. NET 6 or later, then use the C#/WinRT authoring support to create a Windows Runtime Component. If you are implementing an out-of-process background task in a C# desktop application with. ![]()
