  1. Introduction to .NET

  2. .NET Presentation :: Getting Started Getting Started Common Questions: • Isn’t .NET development expensive? • If .NET was important then we would learn about it at University • .NET is proprietary and goes against industry standards

  3. .NET Presentation :: Getting Started My Project • Task: To create a personal blog • Why? • To act as a resume to potential employers, to keep a record of my developments and to gain a reputation as a community orientated developer. http://www.kgbnetworks.com/

  4. .NET Presentation :: Student Resources • The MSDN Academic Alliance program gives students access to the latest Microsoft software. Current products that are freely available to students are Windows XP Pro, Windows Server 2003, Visio Professional, Project Professional and Visual Studio .NET 2003 Academic. • MSDN Connection is a free program which gives students access to a number of services. This includes free ASP.NET hosting, a bi-monthly MSDN Australia Magazine, 20% off MSPress books and discounts on training and certification.

  5. .NET Presentation :: Student Resources • Although you can access the full version of Visual Studio through the MSDNAA program, you can also download the Express Editions for free from the Microsoft website • The Visual Studio Express Edition website is http://lab.msdn.microsoft.com/express/ • The versions available for download are: • Visual Web Developer 2005 Express Edition • Visual Basic 2005 Express Edition • Visual C# 2005 Express Edition • Visual C++ Express Edition • SQL Server 2005 Express Edition • Visual J# Express Edition

  6. .NET Presentation :: VS.NET Express Edition 2005

  7. .NET Presentation :: Development Isn’t .NET development expensive? Cost Summary:

  8. .NET Presentation :: Development If .NET was important then we would learn about it at University • The following Universities offer .NET based courses: • The University of Melbourne – 2 courses • The University of Swinburne – 13 courses • RMIT – 9 courses • Charles Sturt University – 12 courses • University of Technology Sydney – 4 courses • Queensland University of Technology – 10 courses

  9. .NET Presentation :: Other Languages But I like my language better! • That is ok too! Microsoft has made sure the .NET platform supports a number of different languages: • Microsoft Languages: Visual Basic, C#, J# • Other Languages: Java, Perl, Python, C++, Jscript, Pascal, Small Talk, APL, Cobol, Eiffel, Fortran and Forth • These are referred to as Common Language Specification (CLS) compatible programming languages

  10. .NET Presentation :: Other Languages I know Java, but where do I start with .NET? • The Java to .NET migration workshop is a good place to start • Located at http://msdn.microsoft.com/vstudio/java/migrate/workshop/ • This workshop has numerous examples with full source code as well as written and video demos. • Examples include: • Automatic Java -> J#.NET migration • JSP -> ASP.NET migration • Java -> .NET user interface migration

  11. .NET Presentation :: KGB Networks Development Starting with ASP.NET • Example code to connect to a MySQL Database: ASP.NET Code: <%@ Page Language="C#" %> <%@ Import Namespace="System.Data.Odbc" %> <script runat="server"> using(OdbcConnection con = new OdbcConnection(ConnStr)) using(OdbcCommand cmd = new OdbcCommand("SELECT * FROM news", con)) </script> PHP Code: <?php mysql_select_db("kgbnetworks",$db); $result = mysql_query("SELECT * FROM news",$db); ?>

  12. .NET Presentation :: KGB Networks Development Performance Comparison • I was curious to see if ASP.NET performed any better even with my tiny example: PHP:http://www.kgbnetworks.com/index.php Page Generation Time: 0.0188382 Seconds ASP:http://www.kgbnetworks.com/Default.aspx Page Generation Time: 0.0156286 Seconds

  13. .NET Presentation :: .NET Web Services That’s great, but… • Let’s see what .NET is REALLY all about. • .NET heavily utilises web services • Web Services are based on W3C open standards (HTTP, XML and SOAP) • Any application that supports these open standards can communicate with a .NET application locally or remotely

  14. .NET Presentation :: .NET Web Services Creating a Web Service • It is as simple as: Using Visual Studio 2005 Express Edition

  15. .NET Presentation :: .NET Web Services

  16. .NET Presentation :: .NET Web Services Response • The browser shows the response given by your web service in XML format: • Advantages: • Test your web service locally before deploying it • Allows external developers to play with your web service without having to write a single line of code • Useful for testing and isolating bugs in your system.

  17. .NET Presentation :: Conclusion Your next step • Download Visual Studio Express Editionhttp://lab.msdn.microsoft.com/express/ • Find or create some web services to interact with (Plenty of good examples at www.xmethods.net) • Write some code that consumes or serves content via SOAP and XML • Publish it on a web site, as an application or both!

  18. Thank you!
