What methods are available for controlling and handling asynchronous tasks in programming?

In C#, the most commonly used methods for controlling and handling asynchronous tasks are:

• async/await — allows writing asynchronous code that looks like synchronous, simplifying reading and result handling.
• Task and Task<TResult> — represent asynchronous operations, enabling launching, combining, and controlling tasks.
• ContinueWith — allows setting a continuation after a task completes.
• CancellationToken — used for canceling asynchronous operations.
• Task.WhenAll and Task.WhenAny — allow waiting for multiple tasks to complete simultaneously or for the first one to complete.

Example of using async/await:

public async Task<int> GetDataAsync()
{
    // Asynchronous call, e.g., a request to a web service
    int result = await SomeAsyncOperation();
    return result;
}
