So what’s wrong with the old model?
EXE ProgramEXE
Program
Lack of support for different hardwarePrograms were compiled to x86 code.
Weak integration with Internet/WWWCode and WWW code where seenas separate entities.
Lack of security IntegrationMost programs where written with little careabout security
Code.asp<%
val1 = 10val2 = 20result = Cstr(val1) + Cstr(val2)response.write "<BR>Value is " & resultresult = val1 + val2response.write "<BR>Value is " & result
%>
Code.asp<%
val1 = 10val2 = 20result = Cstr(val1) + Cstr(val2)response.write "<BR>Value is " & resultresult = val1 + val2response.write "<BR>Value is " & result
%>
Difficult to integratedifferent languages
Poor version control for system components

So what’s wrong with the old model?
EXE ProgramEXE
Program
Poor robustnessWhere applications often crash
Poor pre-run checkingThis is where applications often crashed on run-time
Difficult deployments
Lack of sharing between applications
Poor integration with differentdata sources, such as XML, databases,and text files.
Too much support for legacy code

A Quick Introduction to Object-Orientation
Parameter Cup 1 Cup 2 Cup3Shape (Standard/Square/Mug) Standard Square MugColour (Red/Blue/Green) Blue Red GreenSize (Small/Medium/Large) Small Large SmallTransparency (0 to 100%) 100% 50% 25%Handle type (Small/Large) Small Small Large
In object-orientation:A collection of parameters defines a class.
Class for the cup is thus: Shape, Colour,Size, Transparency, HandleType.
In object-orientation: Objects arecreated from classes.

Advantages:-Minimal language.-Standardized.-Flexible.
Disadvantages:-Weak checking for errors.-Focused on proceduresrather than data.
-Lack of support for graphics(such as Windows).

Why C#?The gap between C and VB is now closed as both provide an excellent environment for software development.
VB.NET is aimed at Microsoft Office and WWW-based Applications, as it integrates well with VBA and ASP. VB has traditionally supported unstructured code, but this has now changed.
C# is aimed at engineering applications, and allows for more flexibility, such as using pointers. There is also a great amount of code developed for many different applications, such as DSP, interfacing, and so on.
