  1. .NET Overview Geoff Snowman .NET Evangelist gsnowman@microsoft.com

  2. Agenda • .NET Goals • .NET Framework and Languages • Application Types • Case Study

  3. App Dev Trends – Late ’90s • Application Integration troubles • XML • Windows forms hard to deploy • Web forms hard to develop • Many inconsistent APIs • Application drives language choice

  4. .NET Solution • Clean Start for API Design • Object-Oriented Approach • Support for Many Languages • XML • Drive Vision across all Products

  5. .NET – Microsoft’s Vision of a New Generation for Application Development

  6. Agenda • .NET Goals • .NET Framework and Languages • Application Types • Case Study

  15. Agenda • .NET Goals • .NET Framework and Languages • Application Types • Case Study

  16. Windows Forms • XCOPY Deployment • Web Deployment • Side by Side DLLs • VB provides full functionality

  17. Demo

  18. Web Forms • Event-Driven Programming Model • Server Controls • Code Behind • ADO.NET • Session State Scalability • IIS 6.0 • High-Performance Caching • Multiple Authentication Techniques

  19. Server Controls • Programmable, server-side objects • Properties, methods and events • Encapsulate both behavior and rendering • HTML, XML, WML, script, etc. • You can create server controls • Custom controls • User controls • Or derive from existing controls

  20. ASP.NET Pages: Part Declarative, Part Code • Combines declarative tags (HTML, ASP directives, server controls and static text) with code • Unlike ASP, good separation provided between code and tags single file separate files (“code-behind”) code <tags> code <tags> Form1.aspx Form1.aspx Form1.vb

  21. Classic ASP vs. ASP.NET Classic ASP ASP.NET • No separation of presentation from business logic • No built-in support for up/down level browsers • Spaghetti code • Limited session management • Clean separation of presentation logic from business logic • Controls render to support browser • Server controls remove spaghetti code • Session mgt now supports separate session server or db server Presentation Tier • Scripted • Top-down processing • Limited error handling • No support for XML/XSL • Compiled • Event-based programming • Structured error handling • Full support for XML data, web services, XSLT transformation Programming Model • IDE allows debugging from UI to DB • Very high performance • Xcopy deployment model • Full access to windows or custom security model • Full support for object, page caching • Difficult debugging • Mediocre performance • Difficult deployment • No built in security • No support for caching Development Features

  22. Demo

  23. Windows Services • Easy to create in any .NET language • INSTALLUTIL supplied by .NET Framework

  24. Smart Device Applications (2003) • .NET Compact Framework • Created using standard .NET tools and languages

  25. Demo

  26. Mobile Web Applications (2003) • Server controls • Markup optimized by device • Created using standard .NET tools and languages

  27. Mobile Web Applications Broad device support PocketPC, Palm, RIM, Cell phones Online Server side logic Browser-based UI No client installation Smart Device Extensions Target rich clients Pocket PC/Phone edition, Smartphones, Windows CE.NET Offline and Online Client side logic and data UI flexibility Client side installation Leverage SQL Server CE Mobile Web vs. Rich Client Built in support for XML Web Services

  28. Demo

  29. XML Web Services • Integration between applications • Integration between organizations • Integration between heterogeneous systems .NET Connected Application

  30. Internet connects entities together Email and WWW inherently cross boundaries XML Web Services applies the same platform neutral approach to system integration Platform Neutral Leverage Existing Standards No Rip and Replace E-mail Web Services WWW Connects Applications Connects People ConnectsPeople toInformation XML Web Services Explained

  31. XML Web ServicesFoundation for Programmable Internet • Based on public standards • XML, SOAP, XSD, WSDL • Not bound to any single platform • Protocol and format-based contract • Loosely coupled programming • Preserve and connect existing systems • Broad industry support

  32. XML Web Services Language Independent • J2EE App • BEA Weblogic • Oracle 8i • Solaris • Sun UE 10000 • SAP R/3 • DB2 • AIX • IBM RS/6000 Platform Independent Device Independent • Motorola i85s • J2ME XML Web Services • Compaq iPAQ • Windows CE • StrongARM • PeopleSoft 7.0 • SQL 2000 • Windows 2000/.NET • HP ProLiant • PERL • Apache 2.0 • MySQL • Linux

  33. Promoters group for Web services • Facilitate customer adoption • Ensure interoperability • Not a standards body • Industry alignment around Web services • First testing tools this year • More info: http://www.ws-i.org • 100+ member community

  34. Clients Tools Experiences & Solutions Services Servers Microsoft .NET Web services support across the Microsoft platform

  35. “.NET is a brilliant strategy that enables Microsoft to define the next shift in the software business.” Gartner Group Gartner Web Services Magic Quadrant Ability to Execute IBM Sun HP Oracle Completeness of Vision *Source: Gartner Research, 9/13/2001 Analyst Perspective On .NET “Everyone should build on the XML/SOAP foundation.”Meta Group “Gartner believes Microsoft is now providing more vision and influence regarding this shift than any other vendor.” Gartner Group “.NET is a leading example of what we believe will be the dominant architectural model for the third generation of Internet applications.” Patricia Seybold Group

  37. Pet Shop revisited: Middleware App. Server & Web Services Benchmark • MiddleWare Co. re-test of J2EE vs. .NET Per./Scale • Spent 4 months testing J2EE and .NET reference applications • Developed new J2EE application optimized for performance • Conducted new series of comprehensive benchmarks • All results taken by and certified by Middleware Company • Includes Web Application, Web Services and Distributed Transaction benchmarks • Report available at http://www.middleware-company.com/j2eedotnetbench • Downloadable code, test scripts, discussion forum also available

  38. Web Application BenchmarkTests n-tier Web application hosting Windows Server 2003 outperforms J2EE by 339% on the Web application benchmark
