ASP.NET is part of Microsoft's overall .NET framework, which contains a vast set of programming classes designed to satisfy any conceivable programming need. In the following two sections, you learn how ASP.NET fits within the .NET framework, and you learn about the languages you can use in your ASP.NET pages.
The .NET Framework Class Library
Imagine that you are Microsoft. Imagine that you have to support multiple programming languages—such as Visual Basic, JScript, and C++. A great deal of the functionality of these programming languages overlaps. For example, for each language, you would have to include methods for accessing the file system, working with databases, and manipulating strings.


ASP.NET是微軟.NET框架總體戰(zhàn)略的一部分。它包含了一組滿足各種可以想象到的需求的類。在之后的兩個(gè)部分，你將會學(xué)到ASP.NET是怎樣融合到.NET框架中去的，而且你將會學(xué)到可以在ASP.NET頁面中使用到的語言。

.NET框架類庫
假設(shè)你就是微軟，假設(shè)你必須支持多語言編程，例如VB,JS,C++。這些語言的很多函數(shù)都重復(fù)了，比如對于每種語言，你都必須包含一些訪問文件系統(tǒng)，與數(shù)據(jù)庫打交道，以及處理字符串的函數(shù)。
