IT管理漏洞
Apps 孤島
These trends are causing the Enterprise IT to fragment in two big areas:
LOB Apps: These are the traditional, core apps to the business. These apps have high requirements of quality, predictability, and maintenance but they are suffering slower times to market and lack of flexibility. Strict processes avoid these apps to stay competitive in a world where agility, adapt to change, and time to market are critical to succeed.
Modern Apps: LOB Apps constraints can not support the agility and flexibility needs of modern apps. Because of that reason Enterprises are creating a second muscle with a different speed in the organization. While this muscle can deliver on those needs, it creates a silo in the org with intrinsic problems of quality assurance, predictability, and maintenance. Apps are created on demand, with low to none planning and architecture and without orchestration between them. As time evolves, this turns into a “big ball of mud” with applications that can’t talk with each other and are difficult to maintain and evolve.

趨勢 改變
更貼近終端用戶
面業IT消費化的挑戰
手持智慧性裝置增殖
經濟規模成長
無所不在且龐大的資料
The two big IT trends that are shaping the future of Enterprise LOB Apps are:
Mobility and devices proliferation: The proliferation of consumer devices in different form factors and always connected are impacting the way Enterprises are not only defining their direct-to-consumer channels. The availability of these devices also enables new scenarios inside a company (for example mobile workforces) and, because of the consumerization of IT, also the way traditional LOB apps are consumed internally in a company.
Cloud computing: Initially evaluated by Enterprises as a mechanism to embrace economies of scale and lower costs, cloud computing and specially Hybrid IT is also matching the needs of the new applications of always connected devices for LOB apps.

16. WinRT in C#

17. C#版的WinRT App… WinRT APIs 對於硬體裝置、作業系統與服務提供了豐富的功能

C#版的WinRT App…
WinRT APIs 對於硬體裝置、作業系統與服務提供了豐富的功能
WinRT APIs 可以和 C#、JavaScript與C++搭配的非常順暢
WinRT APIs 是非同步的(Asynchronous)
You just saw that WinRT leverages the Async pattern to keep the UI responsive.. This happens across all languages..
The WINRT API has meta data that the platform uses to create projections that make using the API very natural..
There is a lot of power behind WInRT… a few lines of code and we had a dialog selecting a file using a common UX paradigm that all users will be familiar with promptly..

Projection
CLR
Projection
C#/VB App
ECMA 335
Different languages work together.
Write Library code in C++ or C# consumable by all (but must be included in package).
Subset of Win32 APIs
Again projection
JS casing example
Control type differences across.
Mix and match different languages. Windows runtime objects or components basically Dlls WinMD files, can use subset of Win32 APIs, can expose functionality to all languages through “projection” We take care of making sure that these projections work in the way the origional language intended, controling types, casing, etc. Allows writing native C++ code with xaml UI.

25. .NET 以往處理非同步運算的方法 直接使用 thread 使用 thread pool
TechReady 14
9/21/ :25 AM
.NET 以往處理非同步運算的方法
直接使用 thread
Thread t = (new Thread(..)).Start()
使用 thread pool
ThreadPool.QueueUserWorkItem( (s)=>Foo(s) )
Event-Based callback functions
WinForms 時代
APM (Asynchronous Programming Model，導入Begin/End 模式；Task in .NET 4)
有彈性，但仍然難以學習及輕鬆使用
在 Thread-Per-Message 模式 中，每次請求來到，就建立一個新的執行緒，用完就不再使用，然後執行緒的建立需要系統資源，對於一個接受許多請求的情況，不斷的建立新執行緒，會導致系統效能的降低。
Thread pool 模式的概念就是，需要使用執行緒時，在一個執行緒池中尋找可用的執行緒，如果找不到再建立新的，執行緒使用完畢後，留在池中重複使用。

32. Asynchronous APIs in .NET 4.5
.NET 4.5 中已有數百個函式被改寫為新的Async APIs；主要針對C#及VB。
最顯著的例子在 I/O 相關函式庫，如:
任何出現”Async”關鍵字的函式: ReadAsync, WriteAsync, CopyToAsync, FlushAsync, ReadLineAsync, & ReadToEndAsync.
以及在Stream class上的實作: Stream, FileStream, MemoryStream, TextReader & TextWriter.

33. C#/VB Async: Error Handling
To handle the exception in C# or Visual Basic, you use a try/catch block just as you do with synchronous code today:
var title; var feedUri = new Uri(" var client = new Windows.Web.Syndication.SyndicationClient(); try { var feed = await client.RetrieveFeedAsync(feedUri); title = feed.Title.Text; } catch (Exception ex) { // An exception occurred from the async operation }
