In a task-based continuation, we call the member function task::get to get the results of the task. We still have to call task::get even if the operation was an IAsyncAction that produces no result because task::get also gets any exceptions that have been transported down to ...
In both cases, an activeTaskrepresents an asynchronous operation that might not be complete. Theawaitkeyword is where the magic happens. It yields control to the caller of the method that contains theawaitexpression, and ultimately allows the UI to be responsive or a service to be elastic. Whi...
The behavior of thecreate_asyncfunction depends on the return type of the work function that is passed to it. A work function that returns a task (eithertask<T>ortask<void>) runs synchronously in the context that calledcreate_async. A work function that returnsTorvoidruns in an arbitrary ...
TheMainmethod returnsTask, despite not having areturnexpression—this is by design. For more information, seeEvaluation of a void-returning async function. This code doesn't block while the eggs or the bacon are cooking. This code won't start any other tasks though. You'd still put the to...
If your function contains logic that is time-consuming, resource-intensive, or error-prone, you can use asynchronous invocations to allow your programs to respond to traffic spikes in a more efficient and reliable manner. When you invoke a function in asynchronous mode, you do not need to ...
This sample is a WPF application written in C# from theAsynchronous programming with async and await in C# tutorial. The article gives an overview of asynchronous programming, including when to use it and how to write an async method. This sample contains an async function that is used as an...
Description:The asynchronous functions in MySql Connector/Net does not behave as expected. They execute synchronously. F.ex. the function MySqlConnection.OpenAsync() does not return immediately but blocks the calling thread.How to repeat:1) Create a new c# console application named MySqlAsyncBug ru...

You can connect task cancellation with the Windows Runtime Cancel methods in two ways. First, you can define the work function that you pass to create_async to take a concurrency::cancellation_token object. When the Cancel method is called, this cancellation token is cancelled and the normal ...
c.Promise-based asynchronous IO.caller can submit a request at any time and register a callback function for the response data with the Promise; later the receiving thread notifies the Promise of the response data to trigger the callback function. In the above process, the caller thread does...
