Async methods usually return either void, Task, Task<T>, [13]: 35 [16]: 546–547 [1]: 22, 182 ValueTask or ValueTask<T>. [ 13 ] : 651–652 [ 1 ] : 182–184 User code can define custom types that async methods can return through custom async method builders but this is an advanced and rare scenario. [ 17 ]
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 ...
In multithreaded computer programming, asynchronous method invocation (AMI), also known as asynchronous method calls or the asynchronous pattern is a design pattern in which the call site is not blocked while waiting for the called code to finish. Instead, the calling thread is notified when the reply arrives.

Async/await; Asynchronous system, a system having no global clock, instead operating under distributed control Asynchronous circuit, a sequential digital logic circuit not governed by a clock circuit or signal; Asynchronous communication, transmission of data without the use of an external clock signal
In computer science (especially parallel computing), synchronization is the coordination of simultaneous threads or processes to complete a task with correct runtime order and no unexpected race conditions; see synchronization (computer science) for details. Synchronization is also an important concept in the following fields: Cryptography; Lip ...
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.
In computer science, asynchronous I/O (also non-sequential I/O) is a form of input/output processing that permits other processing to continue before the I/O operation has finished. A name used for asynchronous I/O in the Windows API is overlapped I/O .
