Introduction to ASP.NET

• From RVH TECHNOLOGIES

4

• Approach

• Get the BIG picture before programming
• Why? then How?
• Principles and practices know the concepts and
  know how to design and implement an application.
• In the industry design then coding

5

• What is a Computer?

From the Websters New World Dictionary 1. A
person who computes. 2. A device used for
computing (an electronic machine which by means
of stored instructions and information, perform
rapid, often complex calculations or compiles,
correlates, and selects data).
6

• What is a program and what is programming?

Programs stored computer instructions for data
processing. Programming Data Structures
Algorithms Professor Donald E. Knuth
7

• What Types of Programs?

(1) Stand Alone MS PowerPoint (2)
Web/Internet-based (a) Client-side
client-side JavaScript (b) Server Side
ASP.NET, JSP, Web Services 3-Tir
Enterprise Applications (c) Both-sides
Apps (3) Cloud Applications on the Cloud.
Everything is on the Internet and the Internet is
a huge computer. Why? Code
Reuse!
8

• Traditional Compilation/Linking (C/C)

9

• Common Binary Code?

• Java Intermediate Language Java Bytecode

Java Compiler (javac) on OS2
Java Bytecode (.class)

• Program statements are interpreted one at a time
  during the run-time.

11

• JIT Compiler

• An interpreter interprets intermediate code one
  line at a time. Slow execution.
• A JIT (Just-In-Time) Compiler compiles the
  complete code all at once just into native binary
  code before execution. Faster execution.

12

• JIT Complier Java Bytecode Compiler

• All programming statements are compiled at
  compile time.

13

• OS-Independent Code Intermediate Languages

• The trend to support OS-independent binary code
  is to compile the source code into the binary
  format of an intermediate language.
• And to provide an interpreter for the
  intermediate language on each OS to translate the
  binary code of the intermediate language into the
  native binary code of the OS.

• .NET OS-Platform-Independence

16

• The Programming Language for .NET C

C (0) C2n n 0, 1, 2, gt C, C,
C (1) The most advanced programming language to
date (3) OOP (Object-oriented Programming) (4)
EDP (Event Driven Programming) (5) Dynamic type
generation (6) Platform-independent? Code runs
on any platform with .NET runtime (7) Visual
Studio
17

• A Common Language?

18

• .NET Common Language Runtime

• To make .NET language independent, CLR (Common
  Language Runtime) is defined as the runtime
  environment.
• CLR defines CTS (Common Type System) which
  should be followed by all languages to be used in
  the .NET framework.
• Syntax int, for, ..
• Semantics multiple inheritance is not allowed
  in CTS
• The code that follows CTS standard is called
  managed code.
• regular C supports multiple inheritance
• managed C does not support multiple
  inheritance

• CLI (Common Language Infrastructure)
• CLR/CTS for Everyone?

22

• CLI Common Language Infrastructure

• A specification defines an environment for
  multiple high-level languages to be used on
  different computer platforms.
• Created by Microsoft based on .NET, standardized
  by MS, Intel, HP and others, ratified by ECMA and
  ISO.
• .NET is an implementation of CLI for desktop
  systems.
• .NET Compact Framework is an implementation of
  CLI for portable devices.
• Open Source implementations Mono development
  platform (Novell), Portable .NET (dotGNU)

24

• Even though, CLI/CTS/CLR can make a program
  written in any language to run on any platform,
  the entire program (including all libraries used)
  has to be on the platform before running.
• Can we have part of a program on one computer and
  another part of the same program on another
  computer?
• Distributed Computing. A program is divided into
  multiple parts and different parts are distribute
  on different computers.
• e.g. virtual surgery.

25

• Web Enabled Distributed
• .NET

26

• What is .NET?

.Net is a framework for developing
OS-platform-independent, programming-
language-independent, web-enabled, distributed
applications.
27

• .Net is Web-enabled and Distributed

• To run distributed code on the web, we need a
  standard way to register the code and a standard
  way to access the code.
• Registration
• UDDI Registry Universal Description, Discovery,
  and Integration.
• Access
• SOAP Simple Object Access Protocol
• WSDL Web Service Description Language

• .NET Framework Compositions

• Common Language Runtime (CLR ) provides the
  runtime environment for MSIL code.
• Framework Class Library (FCL) provides
  standard libraries for developing common .Net
  applications.

  Studio
