Introduction to .NET
.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

My Project
Task: To create a personal blog
http://www.kgbnetworks.com/
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.

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
.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

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
.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);
?>

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
.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
.NET Presentation :: .NET Web Services
Creating a Web Service
It is as simple as:
Using Visual Studio 2005 Express Edition
.NET Presentation :: .NET Web Services
.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.
.NET Presentation :: Conclusion
Your next step
Download Visual Studio Express Edition
http://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!
Thank you!
