An asynchronous request takes the same amount of time to process as a synchronous request.
If a request makes a web service call that requires two seconds to complete, the request takes two seconds whether it's performed synchronously or asynchronously.
A WPF window class : This runs, but the WPF function window is still blocked once the worker method starts.
I need to know how to arrange the async/await/task declarations to allow A) the worker method to not block the gui window B) let the worker method update the gui window C) allow the gui window to stop interrupt and stop the worker method Any help or pointers are much appreciated.
The await keyword is syntactical shorthand for indicating that a piece of code should asynchronously wait on some other piece of code.
NET Framework 4.5 builds on this asynchronous support with the await and async keywords that make working with Task objects much less complex than previous asynchronous approaches.
NET 4.5 default maximum of 5, 000 threads would consume approximately 5 GB more memory than an application able the service the same requests using asynchronous methods and only 50 threads.
When you're doing asynchronous work, you're not always using a thread.
In a web app that sees a large number of concurrent requests at start-up or has a bursty load (where concurrency increases suddenly), making web service calls asynchronous increases the responsiveness of the app.Additionally, each new thread added to the thread pool has overhead (such as 1 MB of stack memory).A web application using synchronous methods to service high latency calls where the thread pool grows to the .I simplified Bijan's answer to help me think through the problem using the nice formatting provided by Stack Overflow.
By carefully reading and editing Bijan's post I finally understood: How to wait for async method to complete?I have a WPF GUI, where I want to press a button to start a long task without freezing the window for the duration of the task.
