The document discusses Microsoft .NET Framework, which is a set of technologies that allows for software integration and the development of applications that can run across different operating systems and devices. It provides a common language runtime and class libraries. The .NET Framework aims to make applications more scalable, accessible from any device, and allow software to be compiled once and run on any system that supports .NET. It discusses the various versions of .NET Framework and the technologies they include like Windows Forms, ASP.NET, and ADO.NET. Visual Studio is the integrated development environment that can be used to create .NET applications using languages like C# and VB.NET.

2. What is .NET ?Microsoft.NET is a set of Microsoft software technologies for connecting information, people, systems and devices. It enables high level of software integration through the use of XML Web Services.The .NET is a platform that provides a standardized set of services: It’s just like Windows, except distributed over the Internet.It exports a common interface so that it’s programs can be run on any system that supports .Net.Goals of .NETTie all devices to the InternetSoftware as a serviceData and applications accessible on all devicesTruly compile once, run anywhereScalability

3. An Overview on .NET.NET was designed to replace all legacy Microsoft LanguagesJ++, C++, ASP, Visual Basic. Offers Language uniformity..NET Provides Common Intermediate Language IL (or MSIL)IL concept is based on CLI. CLI is a standard not a language. C#, VB.NET, J# compiles into IL. Non-interpreted, Just-In-Time (JIT) Compiled Code. Each client has CLR. CLR is your sandbox. Provides safe environment for code execution.

16. Relationship between CLR, Class Library and Your Application.

17. Benefits of Windows Applications with .NETYou can access data uses ADO.NET. GDI+ allows advanced drawing. Your windows application can make calls exposed through XML web services. You can access OS services. You can develop multi tier distributed applications with the help of .NET.Improved localization support. Windows forms features a security model that is code-based.Extensive XML Supporting classes.With WPF you can build rich media aware applications.

18. Microsoft .NET Framework Introduction to Visual Studio IDE

19. Introducing Visual StudioVisual Studio is a completed set of development tool for building Desktop ApplicationsASP.NET Web ApplicationsXML Web ServicesMobile Applications.Class Libraries, .NET Components & Active X ControlsSupporting Languages are:Visual C#Visual Basic.NETVisual C++More and more.., In addition to above languages you can also access functionality of .NET Framework, which provides access to key technologies that simplifies the development of ASP.NET applications and XML Web Services.

20. Introducing Visual StudioBenefits of Visual Studio over manually writing code on text editors.It make application development faster, easier, and more reliable. Code-aware editors that include statement completion, syntax checking, and other IntelliSense features.Visual designers for forms with drag and drop controls. Visual designers for Windows Presentation Foundation. Integrated compilation and Debugging. Source Control.Project management tools for creating and managing application files, including deployment locally, over an intranet or over the Internet.Support for Win32 based applications and wizards.

21. Introducing Visual Studio Visual Studio gives a very sophisticated MDI application environment. In which you can do just about every thing related to developing your code. It offers the following: Text EditorDesign View EditorSupporting Windows Ability to compile from within the environmentIntegrated DebuggerIntegrated MSDN HelpAccess to other programs.
