.Net Introduction

History Of .NET

Before .Net Technology i.e., from 1990-1998 under microsoft family we have three popular languages.They are
1.VB(Visual Basic)
2.VC++(Visual C++)
3.ASP(Active Server Pages)
* These technologies are having some of the drawbacks as below
Platform dependency:-These technologies will work only on windows operating system.
Not supporting to develop multi type of app:-Using VB and VC++ we can develop only windows applications,Using ASP we can develop only web applications.
*At the same time SunMicroSystems has introduced a technology called JAVA
*JAVA is a platform independent technology and using java we can develop various types of software applications.
*Because of above advantages in JAVA,Microsoft existing technology clients are attracting towards to JAVA.
*To overcome this microsoft has announced about .Net first time in the year 1998 in the meeting called PDC(proffesional Developer Conference)
*In PDC Microsoft has announced about .Net features like below
1. .NET will be platform independent technology
2. .NET is supporting to develop various types of applications.
3. .NET will be supporting for multiple languages
*From 1998 to 2002 Microsoft R&D team has designed .Net technology and finally they have released first version of .Net i.e., .Net1.0 in the year 2002

C#.NET

To develop any type of applications in .Net we need one .Net language and one .Net technology
for example to develop a windows application we need .Net language i.e.,,C#.net and .Net technology i.e., windows forms

• To develop a web application we need one language as C#.Net and a webtechnology called ASP.Net
• C#.Net is a .net language
• C#.net is used for to define the functionality of the application
• C#.net is a object oriented programming language
• Basic features of C#.NET

*Every statement should end with semicolon
EX:- statement 1;
statement 2;
*It is a Case Sensitive language
EX:- int a;
A=10;//it will display a error message
*It will support block level programming
Ex:- Main()
{
statement1;
statement2;//Multiple statements
statement3;
}

ASP.NET

• Asp.net is a one of the web tecchnology
• using asp.net we can develop a web applications
• web applications are web enabled applications that means to consume a web application end user required internet connectivity
• web applications are multi user applications that means at a time consumed by a multiple users
• web application will have a user interface which can be called web page
