This document provides an introduction to .NET, including: - .NET is a platform for creating software using .NET languages and technologies. It currently supports 24 languages such as C#, VB.NET, and PHP.NET. - The .NET framework is a collection of class libraries stored in DLL files that implement object-oriented programming concepts like reusability. - Key features of .NET include being platform independent, supporting language interoperability, being fully object-oriented, and having predefined functionality. - There are three types of assemblies: private, shared, and satellite, which determine how DLL files are distributed and versioned.

- 3. • .NET is a platform to create software • In .NET software= .NET language + .NET technologies • .NET-network enabled technologies or tools • first Microsoft introduced .NET in 1999.at that time only 3 languages integrated in the .NET but present 24 languages are available in the .NET i.e. C#.net ,vb.net, j#.net, F#.net, perl.net, php.net, cobol.net, phythan.net, smalltalk.net, c++ .net, vbscript.net, js.net • visual studio 2012 IDE as front end • SQL server 2008 or 2012 as backend
- 4. • .NET framework: • It is the collection of class libraries. it is the collection of namespaces. • every namespace is one .dll , .dll-dynamic link libraries. dll are implemented by oops concepts. oops -reusability. it supports cui features. • With extension .exe-application(executable) • Without extension .dll-assembly(reusable) • .NET features: • 1.Platform independent • 2.Language interoperability • 3.Pure oops • 4.Case sensitive language • 5.Predefined intelligence(functionalies)
- 5. • Language interoperability: • It supports language cultures. One language source code converts into multiple Languages libraries reference name is called as assembly; • Assemblies: • It is classified into 3 types • 1.private assembly • 2.shared assembly • 3.satellite assembly
- 6. • 1.Private assembly: • This dll file is distributed only one application. it does not supports version, key file, GAC(global assembly cache); • 2.Shared assembly(public assembly): • This dll file is distributed multiple applications. it supports version, key file, GAC. • 3.Satellite assembly : • it supports language cultures. it supports globalization & localization.
- 7. • OOPS:(object oriented programming system) • Suppose we can develops the any project we can gathered the information about classes , properties, methods &data members, member functions & events. • Class: • It is set of properties & methods • BCL: (base class library) • Collection of classes • Object: • Instance variable. every class is mandatory maintains one instance variable.
- 8. OOPS features: • 1.Reusability • 2.Redudacy of the data • 3.Resilence to use. • 1.Data abstraction • 2.Data encapsulation • 3.Inheritance • 4.Polymorphism .NET supports 2 types of applications • 1.Desktop application • 2.Web applications
- 9. • Desktop applications(standalone application): • These applications dev by only one language.ie c#.net, vb.net. these application running through TCP/IP low level protocol. • C# + windows forms = desktop application • ex: yahoo messenger, Google talk, Skype • Web applications: • these applications are dev by only technology.ie asp.net. asp- active server pages • asp.net is the combination of html + client side code + server side code=web application • C# + asp.net= web application • Web services = C# + asp.net (web service template)
- 10. • Html-static pages • Client side code = java script, vb script, jquery etc. • Dhtml = html + scripting • Server side code =.cs, .vb etc.. • these applications running through http high level protocol. • ex: www.gmail.com • Without internet connection with in the LAN we can publish the project through local server (IIS) iis- internet information services.
