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.
AMI is a design pattern for asynchronous invocation of potentially long-running methods of an object. [1] It is equivalent to the IOU ("I owe you") pattern described in 1996 by Allan Vermeulen. [2] [3] In most programming languages a called method is executed synchronously, i.e. in the thread of execution from which it is invoked. If the method ...
Asynchronous Tasks can be awaited in the Main method by declaring the method's return type as Task. static async Task Main ( string [] args ) { await DoWorkAsync ( 42 ); } All the combinations of Task , or Task<int>, and with, or without, the string[] args parameter are supported.
Asynchronous method dispatch (AMD), a data communication method used when there is a need for the server side to handle a large number of long lasting client requests. [3] Using synchronous method dispatch (SMD), this scenario may turn the server into an unavailable busy state resulting in a connection failure response caused by a network ...

The event loop almost always operates asynchronously with the message originator. When the event loop forms the central control flow construct of a program, as it often does, it may be termed the main loop or main event loop. This title is appropriate, because such an event loop is at the highest level of control within the program.
When calling a Windows Runtime asynchronous function, the task is started on another thread or process and the function returns immediately, freeing the app to perform other tasks while waiting for results. [21] The asynchronous model requires new programming language constructs. Each language provides their own way to consume asynchronous APIs ...
Cω (C omega)—for research, extends C#, uses asynchronous communication; C#—supports concurrent computing using lock, yield, also since version 5.0 async and await keywords introduced; Clojure—modern, functional dialect of Lisp on the Java platform; Concurrent Clean—functional programming, similar to Haskell
