1. What is .NET This video is brought to you by SiryMedia

2. .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

3. .NET framework: I t 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. W ith extension .exe-application(executable) W ithout extension . dll -assembly(reusable) .NET features: 1.Platform independent 2.Language interoperability 3.Pure oops 4.Case sensitive language 5.Predefined intelligence( functionalies )

4. Language interoperability: I t supports language cultures. One language source code converts into multiple Languages libraries reference name is called as assembly; A ssemblies: I t is classified into 3 types 1.private assembly 2.shared assembly 3.satellite assembly

5. 1.Private assembly: T his dll file is distributed only one application. it does not supports version, key file, GAC(global assembly cache); 2.Shared assembly(public assembly): T his dll file is distributed multiple applications. it supports version, key file, GAC. 3.Satellite assembly : it supports language cultures. it supports globalization & localization.

6. OOPS:(object oriented programming system) S uppose 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.

7. 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

8. 1.desktop applications(standalone application): T hese 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 2.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)

9. H tml-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 W ithout internet connection with in the LAN we can publish the project through local server(IIS) iis -internet information services.
