I'm new to .Net WebApi, as I know it's preferable to use async APIs instead of sync ones, but what is the difference? if the API is sync and has been called from a client, and another call from another client, as I checked, no interruption will happen, and both calls will go t...
I use linux'smvto move them from the local machine to NFS only when they are completely written, so there "should" never be an incomplete state on the NFS. Could this problem have something to do with sync vs async? Right now I'm using async. From my understanding, async just means ...

a) 阻塞模式:Blocking + Sync b) 非阻塞模式:Non-Blocking + Sync。App通过不停调用send/recv获取数据。 c) select模式:Blocking + Non-Sync。和a)的区别在于,阻塞在select上而不是send/recv上。select保证后续的send/recv操作不会阻塞,看起来好像是Non-Blocking一样——但实质上仍然是Blocking模式。 d) WSAE...

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...

I'm diving into adopting the 'new' async/await style of coding (I know, it's old news at this point, but I could only get to it now), and so I'm all pumped to get my code to go eleven and therefore I wrote a small data-downloader class. It has one method, well two: one...
