內(nèi)容簡介

　　本書為框架設(shè)計人員和相關(guān)專業(yè)人員設(shè)計成功的框架以及可重用的軟件提供了非常實用的指導(dǎo)。本書主要討論框架的設(shè)計，雖然針對的是.NET 平臺，但其中的許多規(guī)范對其他平臺的框架設(shè)計同樣具有借鑒意義。書中匯集的規(guī)范體現(xiàn)了微軟眾多開發(fā)人員的經(jīng)驗和智慧，已經(jīng)成為微軟開發(fā)下一代重量級產(chǎn)品的設(shè)計規(guī)范。.隨書光盤中包括本書內(nèi)容的視頻演示、API規(guī)范樣例等。...

作者簡介

　　本書提供作譯者介紹Krzysztof Cwalina于艾奧瓦大學(xué)獲得計算機(jī)科學(xué)學(xué)士、碩士學(xué)位，是微軟公共語言運(yùn)行時的程序主管。他最初為.NET框架的第一個版本設(shè)計API。他還曾負(fù)責(zé)框架中的幾個命名空間，包括System.Collections、System.Diagnostics和System.Messaging等，同時他還是FxCop小組的最初成員之一。目前，他在整個公司范圍內(nèi)負(fù)責(zé)開發(fā)、推廣設(shè)計規(guī)范并將其應(yīng)用到.NET框架的WinFX中。Brad Abrams于北卡羅來納州立大學(xué)獲得計算機(jī)科學(xué)學(xué)士學(xué)位，是微軟公司公共語言運(yùn)行時和.NET框架小組的創(chuàng)立成員之...
