History of programming languages
1- Microsoft .Net Framework
.NET Framework (pronounced dot net) is a software framework developed by Microsoft that
runs primarily on Microsoft Windows. It includes a large class library known as Framework
Class Library (FCL) and provides language interoperability(each language can use code written
in other languages) across several programming languages. Programs written for .NET
Framework execute in a software environment (as contrasted to hardware environment), known
as Common Language Runtime (CLR), an application virtual machine that provides services
such as security, memory management, and exception handling. FCL and CLR together
constitute .NET Framework.
FCL provides user interface, data access, database connectivity, cryptography, web
application development, numeric algorithms, and network communications.
Programmers produce software by combining their own source code with .NET
Framework and other libraries. .NET Framework is intended to be used by most new
applications created for the Windows platform. Microsoft also produces an integrated
development environment largely for .NET software called Visual Studio.
2-Different DOTNET Types of Applications
There are three main types of application that can be written in C#:
1. Winforms : Windows applications have the familiar graphical user interface
of Windows with controls such as buttons and list boxes for input.
2. Console: Console applications use standard command-line input and output
for input and output instead of a form.

3. Web Sites.
3- Starting Visual Studio (2008/2015)
-Double click on Microsoft Visual Studio (2008/2015) icon on desktop.
OR
-Open the Start menu, select All Programs, and then select Microsoft Visual Studio 2008/2015.

4- Create First Winforms application
Step 1: Start Visual Studio
Open the Microsoft Visual Studio 2008/2015.
Step 2: Create a new project
Go to File -> New Project, And then New Project Dialog Appears.
In the New Project Window, Select Visual C# as Project type and Windows Forms
Applications as the template. Give Name and Location to your project and finally
click OK button to create our first C# project.

6
Step 3: Design the user interface.
When the project is created, you will see the designer view of your interface as
follows.
Form Designer View

7
In this designer view of the form (Form1.cs [Design]), you can design the user
interface of the single form. To do that, we use the 'Toolbox' which contains the
items that you can add to your form. Toolbox is placed on the left side of your
visual studio. If it is not visible go to View -> Toolbox to show the Toolbox.
Toolbox
It contains Labels, Buttons, Check Boxes, Combo Boxes and etc. This can be used
to design your interface. To add elements from the Toolbox to your form double
click the item or drag the item to your form.
Now add a Button Control to your form by simple dragging a Button control into
the form designer view. Finally it looks like below.
Now our form contains two elements. Those are form and the button control.
These elements have properties such as name, text, background color, fore color,

8
etc.... To see properties for a control, select the control and all the properties are
displayed in the Properties Window which appears on the right side of your visual
studio. If it is not visible, Go to View -> Properties Window.
Select the button and view properties as follows.
Now set the text to 'Show' for the button.

9
Step 4: Writing the code
Double click on buttun1 to write the code
private void button1_Click(object sender, EventArgs e)
{
MessageBox.Show("Hello World!");
}
Step 5: Compile the code
To compile the code Go to Build -> Build HelloWorld
Step 6: Running the application
To run/execute the program press F5.
Running Application.

6- Create First Web application
Building Your First Web Application Project
Creating a New Project
Select File->New Project within the Visual Studio 2005 IDE. This will bring up the New Project
dialog. Click on the “Visual C#” node in the tree-view on the left hand side of the dialog box and
choose the "ASP.NET Web Application" icon:
Visual Studio will then create and open a new web project within the solution explorer. By
default it will have a single page (Default.aspx), an AssemblyInfo.cs file, as well as a web.config
file. All project file-meta-data is stored within a MSBuild based project file.

11
Opening and Editing the Page
Double click on the Default.aspx page in the solution explorer to open and edit the page. You
can do this using either the HTML source editor or the design-view. Add a "Hello world" header
to the page, along with a calendar server control and a label control (we'll use these in a later
tutorial):

12
Build and Run the Project
Hit F5 to build and run the project in debug mode. By default, ASP.NET Web Application
projects are configured to use the built-in VS web-server when run. The default project
templates will run on a random port as a root site (for example: http://localhost:12345/):

13
You can end the debug session by closing the browser window, or by choosing the Debug->Stop
Debugging (Shift-F5) menu item.
Customizing Project Properties
ASP.NET Web Application Projects share the same configuration settings and behaviors as
standard VS 2005 class library projects. You access these configuration settings by right-clicking
on the project node within the Solution Explorer in VS 2005 and selecting the "Properties"
context-menu item. This will then bring up the project properties configuration editor. You can
use this to change the name of the generated assembly, the build compilation settings of the
project, its references, its resource string values, code-signing settings, etc:

14
ASP.NET Web Application Projects also add a new tab called "Web" to the project properties
list. Developers use this tab to configure how a web project is run and debugged. By default,
ASP.NET Web Application Projects are configured to launch and run using the built-in VS Web
Server (aka Cassini) on a random HTTP port on the machine.
This port number can be changed if this port is already in use, or if you want to specifically test
and run using a different number:

15
Alternatively, Visual Studio can connect and debug IIS when running the web application. To
use IIS instead, select the "Use IIS Web Server" option and enter the url of the application to
launch, connect-to, and use when F5 or Control-F5 is selected:

16
Then configure the url to this application in the above property page for the web project. When
you hit F5 in the project, Visual Studio will then launch a browser to that web application and
automatically attach a debugger to the web-server process to enable you to debug it.
Note that ASP.NET Web Application Projects can also create the IIS vroot and configure the
application for you. To do this click the "Create Virtual Directory" button.
