WHY Change? 在趨勢的演進中拉距

.NET 簡史以及相容性

.NET 2.0 .NET 3.0

.NET 1.1

2002 2003 2005 2008 2010 2012

橫線上的較新版本皆為in-place updates (就地更新)

.NET 3.5

.NET 4.5 .NET 4

.NET 4.5 於安裝時取代

.NET 4 (或升級Windows 8時) .NET 4 仍可在Visual Studio 2012 中設為目標Framework

Async & Await

.NET 以往處理非同步運算的方法

除了好寫、易讀，debug更容易 private void UseData(String filePath) { Byte[] buff = new Byte[BuffSize]; using (Stream str = File.OpenRead(filePath)) { IAsyncResult asRes = str.BeginRead(buff, 0, buff.Length, (ar) => { if (!ar.CompletedSynchronously) { Int32 len = str.EndRead(ar); ProcessData(buff, len); } }, state: null); if (asRes.CompletedSynchronously) { Int32 lenRes = str.EndRead(asRes); ProcessData(buff, lenRes); } } }

private async Task UseDataAsync(String filePath) { Byte[] buff = new Byte[BuffSize]; using (Stream str = File.OpenRead(filePath)) { Int32 lenRes = await str.ReadAsync(buff, 0, buff.Length); ProcessData(buff, lenRes); } }

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("http://www.devhawk.com/rss.xml");

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

}
