057 - Task methods

Apart from WhenAll, used in on the previous day, Task has also some other static methods that can be useful if we have more than one task to run.

• 📌 Task.WhenAll - to wait for the results of multiple tasks
• 📌 Task.WhenAny - if we don’t care about which one finishes, as long as at least one does
• 📌 Task.WaitAll - to wait on all task, or till cancellation token gets call, or number of milliseconds elapsed

• 📌 Task.WaitAny - similar to the above one, but we only care about one task.

• 📌 Task.FromResult<T> - creates completed task, with specific result
• 📌 Task.FromException<T> - creates completed task, with an exception
• 📌 Task.FromCanceled<T> - creates completed task, due to cancellation token being called

Good to know they exists and use them when needed.
