through the compiler transforming the method into a state-machine-object. The CLR has no safe way to store the address of an "out parameter" or "reference parameter" as a field of an object. The only way to have supported out-by-reference parameters would be if the async feature were do...
Async methods replace the often-seen closure completion callbacks. Completion callbacks were common in Swift to return from an asynchronous task, often combined with aResulttype parameter. The above method would have been written as follows:
await Task.WhenAll(task1, task2); This code “knows” that the invalid parameter exception is raised as part of initiating the asynchronous operation, so it catches the exception only at that point. With Async-Async, the call toDoSomethingAsyncreturns a fakeIAsyncOperationimmediately,...

(or base class). Some events also assume that their handlers are complete when they return. One subtle trap is passing an async lambda to a method taking an Action parameter; in this case, the async lambda returns void and inherits all the problems of async void methods. As a...
In conventional Node.js code, asynchronous functions take a callback as their last parameter and don't return any value. Therefore, calls to these functions arenot awaitable. However, awaitable versions may be obtained with relative ease using something likebluebird'spromisifyAll(), orthunkify. ...
