nt of pages and classes for performing custom caching operations.  — Contains classes for implementing authentication and authorization such as Forms and Passport authentication.  — Contains classes for implementing session state.  — Contains the basic classes used in building the user interface of pages.  — Contains the classes for the HTML controls.  — Contains the classes for the Web controls. .NET FrameworkCompatible Languages For purposes of this book, you will write the application logic for your pages using Visual Basic as your programming language. It is the default language for pages (and the most popular programming language in the world). Although you stick to Visual Basic in this book, you also need to understand that you can create pages by using any language that supports the .NET Common Language Runtime. Out of the box, this includes C (pronounced See Sharp), (the .NET version of JavaScript), and the Managed Extensions to C++. NOTE The CD included with this book contains C versions of all the code samples. Dozens of other languages created by panies other than Microsoft have been developed to work with the .NET framework. Some examples of these other languages include Python, SmallTalk, Eiffel, and COBOL. This means that you could, if you really wanted to, write pages using COBOL. Regardless of the language that you use to develop your pages, you need to understand that pages are piled before they are executed. This means that pages can execute very quickly. The first time you request an page, the page is piled into a .NET class, and the resulting class file is saved beneath a special directory on your server named Temporary Files. For each and every page, a corresponding class file appears in the Temporary Files directory. Whenever you request the same page in the future, the corresponding class file is executed. When an page is piled, it is not piled directly into machine code. Instead, it is piled into an intermediatelevel language called Microsoft Intermediate Language (MSIL). All .NETpatible languages are piled into this intermediate language. An page isn39。 t piled into native machine code until it is actually requested by a browser. At that point, the class file contained in the Temporary Files directory is piled with the .NET framework Just in Time (JIT) piler and executed. The mag。
