The .NET Framework is Microsoft's software technology that provides extensive libraries and tools to simplify development and deployment. It uses a Common Language Runtime (CLR) to manage running code and allow applications written in multiple languages to run on different operating systems and hardware. The .NET Framework includes services like ASP.NET, ADO.NET, and support for XML and web services to make information available anywhere.

3. How Did We Get to .NET? The Evolution of Web Applications First generation of Web applications -non-interactive content (HTML static content) Second generation of Web applications - scalable back-end and a richer User Interface. (DCOM, ASP, CGI, Cold Fusion, dynamic content) Third generation of Web applications (.NET) - using Web protocols and XML to allow better integration between services on the Web

4. What is .NET? .NET is Microsoft’s entry into the Web services arena XML based

5. Why the Move to .NET? DCOM works fine on an Intranet, however: DCOM does not go through firewalls Requires too many open TCP/IP ports Requires Stateful connections Platform dependent Portals provide services however: Non-standard interfaces Hard to integrate with other applications Not designed to use outside the scope of the portal

6. XML Format XML is a tagged mark-up representation of data XML consists of a header section, a schema section, and a data section The header section defines the XML form itself The schema section defines the format of the data contained in the XML document The data section provides the mapped data C:\SicCodes.XML

9. What Is the .NET Framework? A collection of technologies that Unite isolated Web applications Make information available anytime, anywhere Simplify development and deployment How does .NET achieve the above? Web Services ADO.NET Datasets and XML support throughout the platform Rich tools, runtime services and XCOPY Deployment

10. .NET Framework definition: The .NET Framework is a software technology that provides extensive libraries, pre-implemented solutions and a managed run-time environment. Eonfusion is built on the .NET Framework. The .NET Framework delivers more controls, improved start-up performance, AJAX support, and powerful new graphics features for client development. It is designed to make significant improvements in code-reuse, code-specialization, resource management, multi-language development, security, deployment and administration.

17. It is a special run time environment that provides the underlying infrastructure for Microsoft's .NET framework. This runtime is where the source code of an application is compiled into an intermediate language called CIL , originally known as MSIL (Microsoft Intermediate Language). When the program is then run, the CIL code is translated into the native code of the operating system using a just-in-time (JIT) compiler.[citation needed] This intermediate language is used to keep the environment platform-neutral and as a result, supports all .NET languages such as C# or VB.NET

18. Common Language Runtime Design Goals Dramatically simplify application development Provide a robust and secure execution environment Support multiple programming languages Simplify deployment and management

29. .NET Framework languages .NET Framework is designed for cross-language compatibility. Cross-language compatibility means .NET components can interact with each other irrespective of the languages they are written in. This cross-language compatibility is possible due to common language runtime. the output of the compiler is not an executable file but a file that contains a special type of code called the Microsoft Intermediate Language (MSIL).

30. Contd…. Thus, any code compiled by a .NET complier can interoperate with the .NET Framework. all .NET applications are converted to IL before execution all primitive data types are represented as .NET types. This means that, a VB Integer and a C# int are both represented in IL code as System.

31. Languages supported: Language Description/Usage APL It is a language for describing procedures in the processing of information. It can be used to describe mathematical procedures having nothing to do with computers or to describe the way a computer works. C++ C++ derives from the C language. VC++ Visual C++ is the name of a C++ compiler with an integrated environment from Microsoft. This includes special tools that simplify the development of great applications, as well as specific libraries. Its use is known as visual programming.

32. .NET supported languages : C# C# called as C Sharp is a full fledged Object-Oriented programming language from Microsoft built into the .NET Framework. Cobol COBOL was the first widely-used high-level programming language for business applications. It is considered as a programming language to have more lines of code than any other language. Mondrian It is a functional language specifically designed to inter-operate with other languages in an OO environment. Current versions of Mondrian run on .NET. Mondrian also supports ASP.NET, allowing you to embed functional language code in web pages along with C# code.

33. Public Class Person Public Property FirstName As String = "John" Public Property LastName As String Private strSSN As String Public Property SSN() Get SSN() = strSSN End Get Set(ByVal value) strSSN = value End Set End Property End Class There are three properties: FirstName, LastName and SSN. FirstName and LastName are automatic properties. They are automatic because after compiling they look almost like SSN property – the variable that holds property value is created automatically. This above program has Less unit test and Less code.
