COMPILATION PROCESS

.Net application are not compiled as other programing language compilers compile. The compilation process is however more or less same as of JAVA. .Net compiler does this in 2 steps, first it compiles the code into the intermediate language called MSIL(Microsoft Intermediate Language) or CIL(Common Intermediate Language) which is not platform dependent and then CLR's(Common Language Runtime) JIT(Just in Time Compiler) convert MSIL or CIL code into the Native Code. Now this native code is machine dependent, but this does not means that .NET is platform independent as it requires only Microsoft dedicated server(although it comes for Linux too, but with less support and features).



In my last post missed out to discuss some main namespaces of Base Class Library, as BCL is updated and contains additional namespaces in every new release, so i will discuss only important one's

System:- This namespace includes the core needs for programming. It includes base types like String,

DateTime, Boolean, and so forth, support for environments such as the console, math functions, and base classes for attributes, exceptions, and arrays.

System.IO:- Allows you to read from and write to different streams, such as files or other data streams. Also provides a connection to the file system.

System.CodeDom:- This library provides the ability to create code and run it, at runtime.

System.Collections:- Defines many common containers or collections used in programming, such as lists, queues, stacks, hashtables, and dictionaries. It includes support for generics.

System.ComponentModel:- Provides the ability to implement the run-time and design-time behavior of components and controls. It contains the infrastructure "for implementing attributes and type converters, binding to data sources, and licensing components".

System.Configuration:- Provides the infrastructure for handling configuration data.

System.Data:- This namespace represents the ADO.NET architecture, which is set of computer software components that can be used by programmers to access data and data services.

System.Deployment:- Allows you to customize the way your application upgrades when using ClickOnce.

System.Diagnostics:- Gives you the ability to diagnose your application. It includes event logging, performance counters, tracing, and interaction with system processes.

System.DirectoryServices:- Provides easy access to Active Directory from managed code.

System.Drawing:- Provides access to GDI+ graphics functionality, including support for 2D and vector graphics, imaging, printing, and text services.

System.Globalization:- Provides help for writing internationalized applications. Culture-related information, including the language, the country/region, the calendars in use, the format patterns for dates, currency, and numbers can be defined.

System.Management:- Allows you to query for information, such as how much free space is left on the disk, what is the current CPU utilization, which database a certain application is connected to, and much more.

System.Media:- Provides you the ability to play system sounds and .wav files.

System.Messaging:- Allows you to connect to, monitor, and administer message queues on the network and send, receive, or peek messages. .NET Remoting is another name for some of the functionality provided. This namespace is being superseded by Windows Communication Foundation.

System.Net:- Provides an interface for many of the protocols used on networks today, such as HTTP, FTP, and SMTP. Secure communication is supported by protocols such as SSL.

System.Reflection:- Provides an object view of types, methods, and fields. You have "the ability to dynamically create and invoke types". It exposes the API to access the Reflective programming capabilities of CLR.

System.Resources:- Allows you to manage many different resources in the application in order to internationalize an application for different cultures and languages.

System.Runtime:- Allows you to manage the runtime behavior of an application or the CLR. Some of the included abilities are interoping with COM or other native code, writing distributed applications, and serializing objects into binary or SOAP.

System.Security:- Provides the underlying structure of the common language runtime security system. This namespace allows you to build security into your application based on policy and permissions. It provides services such as cryptography.

System.ServiceProcess:- Allows you to create applications that run as a service within Windows.

System.Text:- Supports various encodings, regular expressions, and a more efficient mechanism for manipulating strings (StringBuilder).

System.Threading:- Helps facilitate multithreaded programming. It allows the synchronizing of thread activities and access to data and provides a pool of system-supplied threads.

System.Timers:- Allows you to raise an event on a specified interval.

System.Transactions:- Provides support for local or distributed transactions.

so in my next post i will start with the actual stuff..
