  1. C# Overview and Features

  2. Content • History of C# • Architecture • How to install • Features • Code Sample • Microsoft .NET Platform • Why use C# • Conlusion

  3. What is C#? C# ( pronounced as C-sharp ) is a new Java like language from Microsoft. Microsoft says that C# is a language with the power of C++ and simplicity of Visual Basic. C# supposed to be the best language for Microsoft's .NET programming.

  4. History • In August, 2000, Microsoft, Hewlett-Packard and Intel co-sponsored the submission of specifications for the Common Language Infrastructure (CLI) and C# programming language to the international standardization organization ECMA • During next year the specifications were formulated into standards. • In December, 2001, the ECMA General Assembly ratified the 1st edition of the C# and CLI standards as ECMA-334 and ECMA-335

  5. History II • In April, 2003, ISO ratified the standards • Work at ECMA on the next edition of the Standards is already underway

  6. Architecture • Common Language Runtime • manages code execution • provides services • Compiler • C# compiler is part of .NET Framework SDK • generatesMSIL + Metadata  CPU specific Code (JIT) • Because the runtime supplies one or more JIT compilers for each computer architecture it supports, the same set of MSIL can be JIT-compiled and executed on any supported architecture

  7. How to install • Install Windows 2000 and IE 5.5. • Install Microsoft .NET Framework SDK. Microsoft has it on MSDN site. • After installing these you can write your code in any text editor and save it as .cs extension. • To run the program use the csc command likecsc c:\myprogram.cs

  8. Features • Garbage collection relieves the programmer of the burden of manual memory management. • Variables in C# are automatically initialized by the environment. • Managed execution environment • Variables are type-safe. • native support for the Component Object Model (COM) and Windows®-based APIs. • Built in versioning

  9. Features II • Restricted use of native pointers • With C#, every object is automatically a COM object • Platform and language independent • Inside a specially marked code block, developers are allowed to use pointers and traditional C/C++ features such as manually managed memory and pointer arithmetic.

  10. Features III • Compiler allows use of initialised Variables only • Strong exception handling • Full XML support • Suited well for building Web Services • Array bounds checking • The language is intended for use in developing software components suitable for deployment in distributed environments.

  11. Microsoft .NET Platform • Huge library of Functions • Collection of classes • Windows Application Framework • Web Framework for ASP.NET • Provides access to many kinds of Devices • Developed mainly in C# itself

  12. Why use C# • Full COM/Platform support for existing code integration. • Robustness through garbage collection and type safety. • Security provided through intrinsic code trust mechanisms. • Full support of extensible metadata concepts. • You can also interoperate with other languages, across platforms, with legacy data, by virtue of the following features: • Full interoperability support through COM+ 1.0 and .NET Framework services. • XML support for Web-based component interaction. • Versioning to provide ease of administration and deployment.

  13. Conclusion C# is a modern, object-oriented language that enables programmers build solutions for the Microsoft .NET platform. The framework provided allows C# components to become XML Web services that are available across the Internet, from any application running on any platform.
