Viết các ứng dụng song song và ren là khó khăn. Để giúp, Microsoft đã bổ sung thêm tính năng sửa lỗi cho Visual Studio IDE (phiên bản cao cấp bao gồm các tính năng bổ sung hồ sơ). Để chứng minh các tính năng này, chúng tôi sẽ tạo ra một ứng dụng đơn giản, giao diện điều khiển mới. | CHAPTER 5 PARALLELIZATION AND THREADING ENHANCEMENTS Scheduling on UI thread TaskScheduler supports the ability to schedule items on the UI thread saving you from writing some tedious marshalling code.

To help Microsoft has added additional debugging features to the Visual Studio IDE premium versions include additional profiling features . To demonstrate these features we will create a new simple console application. Create a new project called and enter the following code using static void Main string args Task taskl startAnotherTask Task task2 startAnotherTask Task task3 doSomething static void startAnotherTask Task task4 doSomethingElse static void doSomething 500000 static void doSomethingElse 500000 Put a breakpoint on the line that reads as follows Task task3 doSomething The first feature we will look at is the Parallel Task window. Parallel Task Window This window shows you all the tasks that are currently running and contains features for filtering and jumping directly to where the task is declared. Run the application in debug mode ensuring that you have added a breakpoint to the first line. When the breakpoint is hit on the main menu go to Debug Windows Parallel Tasks Ctrl Shift D K 111 CHAPTER 5 PARALLELIZATION AND THREADING ENHANCEMENTS and you will see a window like the one shown in Figure 5-5 that allows you to review the current status of all your tasks. Figure 5-5. Parallel Tasks debugging window The Parallel Tasks window offers the following functionality You can order the view by clicking the column headings. You can group tasks by status by .
