Is it normal for backend processing to be asynchronous?
Decouple backend processing from a frontend host, where backend processing needs to be asynchronous, but the frontend still needs a clear response. In modern application development, it’s normal for client applications — often code running in a web-client (browser) — to depend on remote APIs to provide business logic and compose functionality.
How does a client respond to an asynchronous request?
The client application makes a synchronous call to the API, triggering a long-running operation on the backend. The API responds synchronously as quickly as possible. It returns an HTTP 202 (Accepted) status code, acknowledging that the request has been received for processing.
How long does it take to respond to an API request?
These APIs may be directly related to the application or may be shared services provided by a third party. Commonly these API calls take place over the HTTP (S) protocol and follow REST semantics. In most cases, APIs for a client application are designed to respond quickly, on the order of 100 ms or less.
What’s the difference between asynchronous and synchronous logging?
Despite having spent several days studying MSDN articles about the Task-based Asynchronous Pattern (TAP), async and await, I’m still a bit confused about some of the finer details. I’m writing a logger for Windows Store Apps, and I want to support both asynchronous and synchronous logging.
What happens during asynchronous execution of a custom action?
During synchronous execution of a custom action, the installer waits for the thread of the custom action to complete before continuing the main installation. During asynchronous execution, the installer runs the custom action simultaneously as the current installation continues.
Why do I have to wait for an Async operation?
Unfortunately, code using Wait (or Result) will block a thread in that context, so the async method cannot complete. Use ConfigureAwait (continueOnCapturedContext: false) as much as possible. This enables your async methods to continue executing without having to re-enter the context.
