Async Task

“Task” is not about “asynchronous processing”.
“Task” is just a task and it is a structure that someone will process the task.
An asynchronous method is a Task (work procedure manual) created by combining Tasks.
Async void absolute use prohibited(except: UI event handler)

The concept of Task.Run is in a nutshell.
“We consider synchronous series of processing as one task”
If combining asynchronous tasks and combining them into one task is an asynchronous method, you may also want to include synchronous processing as one of the tasks. At that time, it is Task.Run that can be used.

Another use is to write an asynchronous lambda expression in Task.Run. This is just like calling the asynchronous method. The only difference from direct call is that “th asynchronous method is explicitly executed in another context.”
