First, the async keyword indicates to C# that the method is asynchronous, meaning that it may use an arbitrary number of await expressions and will bind the result to a promise. [1]: 165–168 The return type, Task<T>, is C#'s analogue to the concept of a promise, and here is indicated to have a result value of type int.
For example, @out is interpreted ... This is a feature of C# 7.1. Asynchronous Tasks can be awaited in the Main method by declaring the method's return type as Task.
In the .NET Framework documentation, the term event-based asynchronous pattern refers to an alternative API style (available since .NET 2.0) using a method named AccomplishAsync instead of BeginAccomplish. [13] [14] A superficial difference is that in this style the return value of the long-running method is passed directly to the callback method.
C# (/ ˌ s iː ˈ ʃ ɑːr p / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms.C# encompasses static typing, [16]: 4 strong typing, lexically scoped, imperative, declarative, functional, generic, [16]: 22 object-oriented (class-based), and component-oriented programming disciplines.
A sample thread pool (green boxes) with task queues of waiting tasks (blue) and completed tasks (yellow), in the sense of task as "unit of work". In computing , a task is a unit of execution or a unit of work.
The exact timing of when tasks in a concurrent system are executed depends on the scheduling, and tasks need not always be executed concurrently. For example, given two tasks, T1 and T2: [citation needed] T1 may be executed and finished before T2 or vice versa (serial and sequential) T1 and T2 may be executed alternately (serial and concurrent)
On Wednesday, Chris Wright, Trump's pick for Energy Secretary told senators in charge of his confirmation that if confirmed, his first task will be to "unleash American energy at home and abroad ...
The Task Parallel Library (TPL) is the task parallelism component of the Parallel Extensions to .NET. [6] It exposes parallel constructs like parallel For and ForEach loops, using regular method calls and delegates , thus the constructs can be used from any CLI languages .
