2.4 TECHNOLOGY USED

INTRODUCTION TO .NET FRAMEWORK

It is a virtual machine that provide a common platform to run an application that was built using the different
language such as C#, VB.NET, Visual Basic, etc. It is also used to create a form based, console-based,
mobile and web-based application or services that are available in Microsoft environment. Furthermore,
the .NET framework is a pure object oriented, that similar to the Java language. But it is not a platform
independent as the Java. So, its application runs only to the windows platform.

Components of .NET Framework

There are following components of .NET Framework:

1. CLR (Common Language Runtime)

2. CTS (Common Type System)
3. BCL (Base Class Library)
4. CLS (Common Language Specification)
5. FCL (Framework Class Library)
10
 6. .NET Assemblies
7. XML Web Services
8. Window Services

Fig 2.1

 CLR (common language runtime)

It is an important part of a .NET framework that works like a virtual component of the .NET Framework to
executes the different languages program like c#, Visual Basic, etc. A CLR also helps to convert a source
code into the byte code, and this byte code is known as CIL (Common Intermediate Language) or MSIL
(Microsoft Intermediate Language). After converting into a byte code, a CLR uses a JIT compiler at run
time that helps to convert a CIL or MSIL code into the machine or native code.

 CTS (Common Type System)

It specifies a standard that represent what type of data and value can be defined and managed in computer
memory at runtime. A CTS ensures that programming data defined in various languages should beinteract
with each other to share information. For example, in C# we define data type as int, while in VB.NET we
define integer as a data type.

 BCL (Base Class Library)

11
The base class library has a rich collection of libraries features and functions that help to implement many
programming languages in the .NET Framework, such as C #, F #, Visual C ++, and more. Furthermore,
BCL divides into two parts:

1. User defined class library

o Assemblies - It is the collection of small parts of deployment an application's part. It contains
either the DLL (Dynamic Link Library) or exe (Executable) file.
1. In LL, it uses code reusability, whereas in exe it contains only output file/ or
application.
2. DLL file can't be open, whereas exe file can be open.
3. DLL file can't be run individually, whereas in exe, it can run individually.
4. In DLL file, there is no main method, whereas exe file has main method.
2. Predefined class library
o Namespace - It is the collection of predefined class and method that present in .Net. In other
languages such as, C we used header files, in java we used package similarly we used "using
system" in .NET, where using is a keyword and system is a namespace.

 CLS (Common language Specification)

It is a subset of common type system (CTS) that defines a set of rules and regulations which should be
followed by every language that comes under the .net framework. In other words, a CLS language should be
cross-language integration or interoperability. For example, in C# and VB.NET language, the C# language
terminate each statement with semicolon, whereas in VB.NET it is not end with semicolon, and when these
statements execute in .NET Framework, it provides a common platform to interact and share information
with each other.

 Microsoft .NET Assemblies

A .NET assembly is the main building block of the .NET Framework. It is a small unit of code that contains
a logical compiled code in the Common Language infrastructure (CLI), which is used for deployment,
security and versioning. It defines in two parts (process) DLL and library (exe) assemblies. When the .NET
program is compiled, it generates a metadata with Microsoft Intermediate Language, which is stored in a file
called Assembly.

 FCL (Framework Class Library)

12
It provides the various system functionality in the .NET Framework, that includes classes, interfaces and
data types, etc. to create multiple functions and different types of application such as desktop, web, mobile
application, etc. In other words, it can be defined as, it provides a base on which various applications,
controls and components are built in .NET Framework.

13
WINDOW FORMS FUNDAMENTALS

Windows Forms is a Graphical User Interface(GUI) class library which is bundled in .Net Framework. Its
main purpose is to provide an easier interface to develop the applications for desktop, tablet, PCs. It is also
termed as the WinForms. The applications which are developed by using Windows Forms or WinForms
are known as the Windows Forms Applications that runs on the desktop computer. WinForms can be
used only to develop the Windows Forms Applications not web applications. WinForms applications can
contain the different type of controls like labels, list boxes, tooltip etc.
Creating a Windows Forms Application Using Visual Studio 2017
 First, open the Visual Studio then Go to File -> New -> Project to create a new project and
then select the language as Visual C# from the left menu. Click on Windows Forms App(.NET
Framework) in the middle of current window. After that give the project name and Click OK.

Fig 2.2
Here the solution is like a container which contains the projects and files that may be required
by the program.
 After that following window will display which will be divided into three parts as follows:
1. Editor Window or Main Window: Here, you will work with forms and code
editing. You can notice the layout of form which is now blank. You will double click
the form then it will open the code for that.
2. Solution Explorer Window: It is used to navigate between all items in solution. For
example, if you will select a file form this window then particular information will
be display in the property window.
14
 3. Properties Window: This window is used to change the different properties of the
selected item in the Solution Explorer. Also, you can change the properties of
components or controls that you will add to the forms.
 Now to add the controls to your WinForms application go to Toolbox tab present in the
extreme left side of Visual Studio. Here, you can see a list of controls. To access the most
commonly used controls go to Common Controls present in Toolbox tab.

Fig 2.3
 Now drag and drop the controls that you needed on created Form. For example, if you can add
TextBox, ListBox, Button etc. as shown below. By clicking on the particular dropped control
you can see and change its properties present in the right most corner of Visual Studio.

15
 Fig 2.4
In the above image, you can see the TextBox is selected and its properties like TextAlign,
MaxLength etc. are opened in right most corner. You can change its properties’ values as per
the application need. The code of controls will be automatically added in the background. You
can check the Form1.Designer.cs file present in the Solution Explorer Window.
 To run the program you can use an F5 key or Play button present in the toolbar of Visual
Studio. To stop the program you can use pause button present in the ToolBar. You can also run
the program by going to Debug->Start Debugging menu in the menubar.

C# Windows Forms is a graphical user interface (GUI) framework that enables developers to create
desktop applications for the Windows operating system. Windows Forms applications are created using
the C# programming language and the .NET framework. They are built by dragging and dropping controls
such as buttons, text boxes, labels, and other user interface elements onto a form.

1. The Windows Forms framework provides a rich set of controls that developers can use to build
applications with. These controls are designed to provide a consistent and familiar user
interface for Windows users. Developers can customize the appearance and behavior of these
controls by setting various properties and handling events.
2. To create a Windows Forms application in C#, you can use Microsoft Visual Studio, which is
an integrated development environment (IDE) that provides a visual designer to create and
layout the user interface elements. The visual designer is a drag-and-drop interface for building
your UI, and you can easily configure each control’s properties through a user-friendly
interface.
3. In addition to the visual designer, Visual Studio also provides a code editor that enables
developers to write the C# code for the application’s logic. Developers can handle events and
perform tasks such as data validation, data manipulation, and business logic implementation.
4. Windows Forms applications are versatile and can be used to create various types of
applications such as data entry, management, and reporting applications, as well as games and
multimedia applications.
Overall, Windows Forms applications provide an easy-to-use and familiar graphical user interface for
Windows users, making it an ideal choice for building desktop applications that require a high degree of
interactivity and user engagement.

C# FUNDAMENTALS

C# is the most common programming language used to develop multiple applications in the.NET
framework, and it was introduced by Microsoft in 2000. It was designed to be a simple, object-oriented
programming language that can be used to create a wide range of applications and software.It features a
clear syntax, an object-oriented nature, and platform independence, which makes it simpler for developers
to organise their code and makes it more legible and manageable.

It is platform-independent in the sense that it may be used to create programmes that operate on different
platforms such as Windows, macOS, Linux, and mobile devices. This makes C# a versatile language.

17
C# Features

 Simple: C# is a user-friendly language that offers a structured approach to problem-solving. it

provides a wide range of library functions and data types to work.

 Modern Programming Language :C# programming is a popular and powerful language that is for
creating scalable, interoperable, and robust applications.
 Object Oriented: C# is an object-oriented programming language, which makes development and
maintenance easier. In contrast, with procedure-oriented programming languages, managing code becomes
difficult as project size grows.

feature significantly enhances program security.

 Interoperability: The interoperability process allows C# programs to perform all the tasks that a native
C++ application.
 Scalable and Updateable: C# is a programming language that is scalable and can be updated
automatically. To update our application, we remove the old files and replace them with new ones.
 Component Oriented: It is widely used as a software development methodology to create applications
that are more strong and can easily scale.
 Structured Programming Language: C# is a structured programming language that allows us to divide
programs into parts using functions, making it easy to understand and modify.
 Fast Speed: The compilation and execution time of C# language is fast.

Example program:

using System;
namespace HelloWorld
{
class Program
{
static void Main(string[] args)
{
console.WriteLine("Hello World!");

minimizes complexity and facilitates maintenance.

Key Components of Software Design:

1. Modularity
The Book Shop Management System is divided into small, manageable modules such as inventory
management, sales processing, and customer management. This simplifies maintenance, enables parallel
development, and ensures reusability.
2. Abstraction
High-level abstractions are used to present the system's functionality while hiding complex implementation
details. For instance, a module for inventory will expose functions like "Add Book" or "Update Stock" while
abstracting the underlying logic.
3. Encapsulation
Data and methods are bundled into classes, such as a "Book" class containing properties like title, author, and
price alongside methods to manage these attributes. Encapsulation protects data integrity and enhances
system security.
4. Separation of Concerns
Different functionalities are assigned to distinct layers, such as the user interface layer for interactions, a
business logic layer for processing, and a database layer for storage. This approach improves system
