Download source - 93.5 KB Introduction Though performance blocking and sluggishness are the tailbacks for any application, we can easily overcome these bottlenecks by using asynchronous programming. But old-style practice for asynchronous programming…

The Task: Events, Asynchronous Calls, Async and Await Almost any software application today will likely contain a long-running process. “Long-running” may be a relative term but in the Windows Runtime it is specifically anything that could take longe…

原文地址:CQRS, Task Based UIs, Event Sourcing agh! Many people have been getting confused over what CQRS is. They look at CQRS as being an architecture; it is not. CQRS is a very simple pattern that enables many opportunities for architecture that may ot…

终结点与服务寄宿 由于最近可能要使用WCF做开发,开始重读蒋金楠的<WCF全面解析>,并整理个人学习WCF的笔记. 蒋金楠的书是我的第一本WCF入门书,虽说硬着头皮啃下来了,但是原理内容太多太多,没有长期的经验是无法掌握的,而且这本书写得太过于偏重原理,并不是一本稍微看看就能速成并实现工作需求的书. 于是这篇文章的目的就是把原理和类结构分析给干掉(毕竟书上都有,我何必抄书?),把一些关键话语和配置方式摘出来,以便日后一旦遇到问题有个速查的手册,也相当于为这本书做了一个索引. 不过不得不说的是,…

We refactor a standard node callback style workflow into a composed task-based workflow. For example we have the code as following: We want to wrap async functions (readFile and writeFile) into Task. Therefore it becomes composeable. const Task = req…
