Description: The ‘WhenAll’ task in C# is a powerful tool that allows you to create a task that will complete only when all provided tasks have finished. This functionality is part of the asynchronous programming model introduced in C# to facilitate writing code that can perform multiple operations simultaneously without blocking the main execution thread. ‘WhenAll’ is particularly useful in scenarios where you need to wait for a set of tasks to complete before proceeding with the next operation, which enhances the efficiency and responsiveness of applications. By using this task, developers can effectively handle multiple I/O operations, such as network requests or database access, thereby optimizing the overall performance of the application. Additionally, ‘WhenAll’ allows for easier error handling, as exceptions from all tasks can be aggregated, simplifying debugging and code maintenance. In summary, ‘WhenAll’ is an essential feature in C# that promotes asynchronous programming and efficient management of concurrent tasks.
