Should I expose async containers for async methods?
Asynchronous methods should not be exposed solely for the purpose of unloading: the consumer of synchronous methods can easily obtain such benefits by using functionality specifically geared towards working with synchronous methods asynchronously, for example, Task.

How is it executed asynchronously?
The easiest way to execute a method asynchronously is to start executing the method by calling the delegate’s BeginInvoke method, work on the main thread, and then call the delegate’s EndInvoke method. EndInvoke might block the calling thread because it doesn’t return until the asynchronous call completes.
What does it mean for a method to be asynchronous?
An asynchronous method call is a method used in .NET programming that returns to the caller immediately before completing its processing and without blocking the calling thread. An asynchronous method runs on a separate thread from the main thread of the application.
How do you create an async method?
We want this method to be asynchronous, so that the UI thread can freely respond to user actions during the download. The first step is to add the async keyword to the method. It appears in the method signature in the same way as the static keyword.
Is the CAN protocol asynchronous?
Controller Area Network (CAN) is an asynchronous serial CSMA/CD+AMP communication protocol for microcontroller networks, supporting real-time distributed control (bit rate up to 1 Mbps) with a very high level of security.
Should I expose async containers for synchronous methods?
If a developer needs to achieve responsiveness or parallelism with synchronous APIs, they can simply wrap the invocation with a method like Task.Run. The idea of exposing “async over sync” wrappers is also a very slippery slope, one that taken to the extreme could result in all methods being exposed in both synchronous and asynchronous forms.
Why does task.run() look like an async wrapper?
It may have a similar signature because it’s returning a Task, but all it’s doing is blocking a different thread. In this sense, using Task.Run() creates a “fake” async method. It looks like an async method, but you’re really just faking it by doing the processing on a background thread.
How to call synchronous wrapper in ThreadPool?
And, let’s say someone has set an upper limit on the number of threads in the ThreadPool to 25 via ThreadPool.SetMaxThreads or via a configuration flag. Now, call the synchronous Foo wrapper method from a ThreadPool thread, for example, Task.Run ( ()=>Foo ()). What happens?
When to use continuation or async wrapper in Java?
The point is that the choice should be left to the consumer. They can implement the asynchronous method, use a continuation to run some code once the operation completes, or just run a synchronous version if scalability isn’t a concern.
