Asp.Net Page Directives

Introduction:

Here we are going to discuss about asp.net page directives here I try to explain about different page directive of asp.net page.

Explanation:

 ASP.NET directives are something that is a part of every ASP.NET page. You can control the behavior of your ASP.NET pages by using these directives. Here’s an example of the Page directive:

Eleven directives are at your disposal in your ASP.NET pages or user controls. You use these directives in your applications whether the page uses the code-behind model or  the inline coding model.

•    ASPNET_ISAPI.DLL forwards the request to the ASP.NET worker process (ASPNET_WP.EXE or W3P.EXE).

•    ISAPI loads HTTPRuntime and passes the request to it. Thus, HTTP Pipelining has begun.

•    HTTPRuntime uses HttpApplicationFactory to either create or reuse the HTTPApplication object.

What is an assembly?

•An Assembly is a  logical unit of code
•Assembly physically exist as DLLs or EXEs
•One assembly can contain one or more files
•The constituent files can include any file types like image files, text files etc. along with DLLs or EXEs
•When you compile your source code by default the exe/dll generated is actually an assembly
•Unless your code is bundled as assembly it can not be used in any other application

•Every assembly file contains information about itself. This information is called as Assembly Manifest.

 Framework

The Microsoft .NET Framework is a software framework that can be installed on computers running Microsoft Windows operating systems. It includes a large library of coded solutions to common programming problems and a virtual machine that manages the execution of programs written specifically for the framework. The .NET Framework supports multiple programming languages in a manner that allows language interoperability, whereby each language can utilize code written in other languages; in particular, the .NET library is available to all the programming languages that .NET encompasses. The .NET Framework is a Microsoft offering and is intended to be used by most new applications created for the Windows platform. In order to be able to develop and not just run applications for the Microsoft .NET Framework 4.0, it is required to have Microsoft's SDK for Windows 7 and .NET Framework 4 (or newer) or Visual Studio 2010 installed on your computer.
