1 WebApi and async methods 13 ASP.Net vs MVC vs WebAPI and UseTaskFriendlySynchronizationContext 4 Changing my server-side WebAPI to get the benefits of async/await 0 When to use Async Task with HttpClient or WebClient 112 Why should I create async WebAPI operations instead of sync ones?
I'm currently learning node.js and I see 2 examples for sync and async program (same one). I do understand the concept of a callback, but i'm trying to understand the benefit for the second (async) example, as it seems that the two of them are doing the exact same thing even tho...
There’s an option you can use to turn off both safety nets: HttpContext.AllowAsyncDuringSyncStages (it can also be set in web.config). A few pages on the Internet suggest setting this whenever you see these exceptions. I can’t disagree more vehemently. Seriously, I...

为什么这是不允许的,详细请看《What’s New for Parallelism in .NET 4.5 Beta》。此特性将方法标记为同步类似于使用lock/SyncLock同步基元包裹整个方法体。 l [SecurityCritical]和[SecuritySafeCritical] (Critical:关键) 编译器在编译一个”async”标记的方法,原方法体实际上最终被编译到新生成的MoveNext()方法中...

可以生成相应的代理类,可以让我们像调用本地代码一样访问web service,而所生成的代码类中对针对每一个web service方法生成3个对应的方法,比如说我们的方法名叫DownloadContent,除了这个方法之外还有BeginDownloadContent和EndDownloadContent方法,而这两个就是我们今天要说的早期的异步编程模式APM(Asynchronous Programming ...
programming model. III. How to do Scalable I/O Operations? The challenges for scalable I/O model are: 1. What code to execute after I/O operations are issued (maybe in async/sync way)? 2. How to detect and What to do when I/O operations are completed? Scalable I/O operations can...
如果SynchronizationContext.Current 不为 null,则它是当前的 SyncContext。(UI 和 ASP.NET 请求上下文是同步上下文上下文)。 否则,它是当前的 TaskScheduler(TaskScheduler.Default 是线程池上下文)。 这在现实世界中意味着什么?首先,捕获(和还原)UI/ASP.NET 上下文是透明完成的: ...
