This sample shows you how to run work items asynchronously using the Windows Runtime thread pool API.
Note This sample was created using one of the universal app templates available in Visual Studio. It shows how its solution is structured so it can run on both Windows 8.1 and Windows Phone 8.1. For more info about how to build apps that target Windows and Windows Phone with Visual Studio, see Build apps that target Windows and Windows Phone 8.1 by using Visual Studio.
This sample demonstrates the following tasks:
- Using a delay timer to trigger a work item to run one time
- Using a periodic timer to trigger a work item to run every time the period elapses
- Submitting a work item to the thread pool to run on the first available worker thread
- Specifying a priority for a work item
- Handling a request to cancel a work item
To obtain an evaluation copy of Windows 8.1, go to Windows 8.1.
To obtain an evaluation copy of Microsoft Visual Studio 2013, go to Visual Studio 2013.
Note For Windows 8 app samples, download the Windows 8 app samples pack. The samples in the Windows 8 app samples pack will build and run only on Microsoft Visual Studio 2012.
