  1. The Microsoft® .NET Framework Presented by Joseph J. Sarna Jr., MCSD JJS Systems, LLC

  2. Agenda • Introduction to .NET and Web Services • The .NET Framework • Common Language Runtime • .NET Framework Services • Common Language Specification • .NET Development Tools

  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. What Is A Web Service? • A programmable application, accessible as a component via standard Web protocols • Defined in terms of the required formats and ordering of messages • You can ask a site for a description of the Web Services it offers • Web Service consumers can be any device - send and receive messages using XML • All built using open Internet protocols

  7. XML Is The Core • Simple, open, broadly adopted • Continues the Web’s open standards • Enables powerful distributed apps • A universal data exchange format

  8. 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. SOAP Simple Object Access Protocol • Internet becomes integration fabric • Broad industry support • IBM, Iona, Ariba, Compaq, Lotus, Commerce-One, HP, SAP, others • Submitted to W3C: • http://www.w3.org/TR/SOAP/ • XML-based integration for web services

  10. Benefits of Web Services • Leverages exiting infrastructure • Allows the choice to buy or build the functionality • Use of tested standard modules for repeatability • Minimizes development time and cost • Allows integration between applications, platforms, businesses

  11. Agenda • Introduction to .NET and Web Services • The .NET Framework • Common Language Runtime • .NET Framework Services • Common Language Specification • .NET Development Tools

  12. 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

  13. .NET Framework, Languages, Tools Visual Studio.NET VB C++ C# JScript … Common Language Specification Web Services User Interface Data and XML Base Class Library Common Language Runtime

  14. Agenda • Introduction to .NET and Web Services • The .NET Framework • Common Language Runtime • .NET Framework Services • Common Language Specification • .NET Development Tools

  15. Common Language Runtime Visual Studio.NET VB C++ C# JScript … Common Language Specification Web Services User Interface Data and XML Base Class Library Common Language Runtime

  16. The .NET Common Language Runtime • Manages running code • Threading • Memory management • Multi-language • Inheritance, Errors, Debugging • Fine-grained evidence-based security • Code access security • Role-based security • Integrated with underlying OS • “No-touch” deployment

  17. Thread Support COM Marshaler Type Checker Exception Manager Security Engine Debug Engine IL to Native Compilers Code Manager Garbage Collector Common Language Runtime Base Class Library Support Class Loader

  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

  19. Agenda • Introduction to .NET and Web Services • The .NET Framework • Common Language Runtime • .NET Framework Services • Common Language Specification • .NET Development Tools

  20. .NET Framework Services Visual Studio.NET VB C++ C# JScript … Common Language Specification Web Services User Interface Data and XML Base Class Library Common Language Runtime

  21. .NET Framework Services • ASP.NET • Logical evolution of ASP (compiled) • Web forms • Manageable code (non spaghetti) • Windows® forms • Framework for building rich clients • ADO.NET, evolution of ADO • New objects (e.g., DataSets) • XML Support Throughout

  22. Some .NET Base Class Libraries System.Web System.WinForms Design ComponentModel Services UI Description HtmlControls Discovery WebControls Protocols System.Drawing Drawing2D Printing Caching Security Imaging Text Configuration SessionState System.Data System.Xml ADO SQL XSLT Serialization Design SQLTypes XPath System Collections IO Security Runtime InteropServices Configuration Net ServiceProcess Remoting Diagnostics Reflection Text Serialization Globalization Resources Threading

  23. Agenda • Introduction to .NET and Web Services • The .NET Framework • Common Language Runtime • .NET Framework Services • Common Language Specification • .NET Development Tools

  24. Common Language Specification Visual Studio.NET VB C++ C# JScript … Common Language Specification Web Services User Interface Data and XML Base Class Library Common Language Runtime

  25. Common Language Specification • What about types? • Common type system (CTS) • Other languages and compilers • Common Language Specification (CLS)

  26. .NET Languages • The .NET Platform is Language Neutral • All .NET languages perform the same • You can leverage your existing skills • Common Language Specification • Consumer: Can use the .NET Framework • Extender: Can extend the .NET Framework • Microsoft provides: • VB, C++, C#, JScript • Third-parties are building • APL, COBOL, Pascal, Eiffel, Haskell, ML, Oberon, Perl, Python, Scheme, Smalltalk

  27. Visual Basic C# Jscript C++ Perl Python COBOL Haskell ML Ada Pascal C SmallTalk Oberon Scheme Mercury APL Eiffel Oz Objective Caml .NET Languages Available (or soon to be)
