Can you explain what the TaskFactory pattern is and what it is used for?

The TaskFactory pattern in C# is a class that provides methods for creating and starting tasks (Task). It simplifies the creation of asynchronous operations and their management.

Main features of TaskFactory:

• Creating tasks with various parameters (e.g., specifying a scheduler or options).
• Starting tasks with delegates (Action, Func).
• Managing the execution context.

Example of usage:

var factory = new TaskFactory();
Task<int> task = factory.StartNew(() => {
    // Long operation
    return 42;
});
int result = task.Result;

TaskFactory is useful when you need to create tasks with specific settings or use a common mechanism for launching asynchronous operations.
