Role-based Security◦ What the user is allowed to do within the

application◦ .NET Roles = Windows Active Directory® groups

Code Access Security◦ What the code is allowed to do on this machine◦ Evidence Based (Policies, Permissions, Evidence)

Cryptography Built In to .NET FX

Evolution, not revolution, of language used by developers worldwide

Builds on existing technology while adding power◦ True OOP◦ Multithreading◦ NT Services◦ Web Services

The fastest way to build scalable applications for industry

C# is the first “component oriented” language in the C/C++ family

Component concepts are first class:◦ Properties, methods, events◦ Design-time and run-time attributes◦ Integrated documentation using XML

Enables one-stop programming◦ No header files, IDL, etc.◦C++ heritage – simplification with no unnecessary sacrifices

Native support for XML Web services Fully integrated with Visual Studio .NET

development environment Full access to the .NET Framework

◦ ASP.NET, ADO.NET, Windows Forms◦ Integration with >20 other languages

Protection of existing investments◦ Use java language syntax on .NET◦ Move applications and skills forward

Better ANSI/ISO conformance Enable seamless, incremental use

of .NET Framework Enhanced ATL Servers Improved ATL and MFC Clients Enhanced STL

Web Form – Next Generation ASP Page Win Form – Next Generation Win32 App Web Services – Key to Interoperability Others –

◦ Server Objects ◦ Console Applications◦ Window Services◦ Mobile Clients ◦ Many more…

Server-side Web Forms and Web Services components separate code from content◦ Developer productivity increases◦ Tools easily use ASP.NET◦ Any programming language: full VB, JScript,

C++, COBOL, Perl, etc.◦ 40% to 70% reduction in lines of code

Compiled No-touch deployment system Intelligent state management Backwards compatible with ASP Controls sense client and adapt output:

HTML, DHTML, WML

A Component That Uses XML & HTTP To Define and Deliver A Service◦ Global reach◦ Based on open set of standards◦ Reuse across platforms◦ Works with any operating system, programming

language, or network◦ Expose legacy code

Different systems can actually talk

XML◦ Universal data format◦ Standards-based integration◦ User-customizable

HTTP◦ Ubiquitous protocol◦ Universally understood

Expose functionality as service◦ No need to learn XML, SOAP, or WSDL◦ Interface is automatically generated◦ Seamless deployment

Reuse existing Web Services◦ VS.NET generates the plumbing◦ Full IntelliSense support

Build and consume with any VS language

Built-in Support for Developing and Consuming Web Services◦ Based entirely on open standards◦ Automatically generates WSDL◦ Automatically provides test page◦ Attribute based – No heavy coding needed

Rich, powerful client UI◦ Control anchoring, visual inheritance◦ Shared across all .NET languages◦ No-touch deployment

Secure◦ Semi-trusted browser component◦ Fully-trusted local application

Full Web Service integration

Evolutionary◦ Existing Skills Migrate Smoothly◦ Interoperates with Existing Applications◦ Extension of WinDNA Architecture

Revolutionary◦ Common Language Runtime◦ Deployment / Versioning (Ends DLL Hell)◦ Web Services & XML Integration◦ Evidence Base Code Access Security

Developers can use any .NET Language The .NET Framework provides a foundation of

classes for developers to build a wide variety of applications

Source code is compiled to MSIL within an Assembly

Assembles contain rich meta data and are the primary units of deployment

MSIL is compiled to native code and executed by the Common Language Runtime
