once it is done.


                       ILUG-Madurai meeting #3

Date : 13-03-2004 (10.45hrs to 12.30hrs)
Venue: Z0 Lecture Hall,

Speaker: Mr. Kaushik Srenevasan <kaushik_srene@xxxxxxxxxxx>


In today's meet we spoke about,

   1. Understanding what .NET is 
   2. Discuss history behind the Mono project 
   3. Demonstrate some Mono components 
   4. Other open source alternatives


.NET  a platform  for  building  and running  the  next generation  of
applications and  XML Web services.  It provides a  highly productive,
standard  based,   enterprise-ready,  Multilanguage  environment  that
simplifies  application development,  enables  developers to  leverage
their  existing  skill  set,  facilitates  integration  with  existing
software,  and  eases  the   challenges  of  deploying  and  operating
Internet-scale applications. The Framework consists of two main parts:
the common language runtime  and a unified, hierarchical class library
that includes a revolutionary advance to Active Server Pages (ASP.NET)
and a loosely-coupled data access subsystem (ADO.NET).



A  development environment  provides a  set of  programmatic services,
exposed through some API to developers using one or more languages.
The  Framework, as any  other development  environment, can  be broken
down into  three fundamental areas:  the runtime the  platform offers,
the libraries it defines, and the languages we can use to target it.


A runtime  is a  piece of  code, written by  the platform  vendor that
provides  our code with  a set  of services.  These services  could be
anything - from  checking security, to implementing a  file system, to
providing access to some piece of hardware.
Almost every program takes advantage of some sort of runtime. Very few
programmers  start a  project  by  writing their  own  file system  or
database engine.  Rather, they make  use of already-written  pieces of
software, like  Linux or mySQL. In  the case of Linux,  the runtime is
the OS kernel, and it provides services like thread management. In the
case of  mySQL, the runtime is  the database engine,  and the services
include things like a SQL engine and transactions.
The Framework provides these services using a layered architecture (as
shown below). In some cases application code uses the CLR directly and
in others indirectly.

The Framework SDK  provides an API to interact  with the runtime. This
API  takes  the form  of  a set  of  classes.  Collectively, they  are
referred to the  Base Class Libraries, or BCL.  Through the classes in
the BCL,  we can interact with  the runtime, influencing  the way that
the runtime's services are provided to us.
The BCL classes also provide a large amount of useful utilities. These
include things like a  new database access library (ADO.NET), ASP.NET,
and   an    XML   parser   with    support   for   the    latest   XML
specifications. There are thousands of classes in the BCL.
Languages: In  order to take advantage  of a set of  libraries and the
runtime we need to use  some programming language with a compiler that
is runtime-aware. There are currently two languages that Mono supports
C# and Mono Basic (VB on Mono)

Standards Based:

The  Framework   provides  explicit  support   for  standards,  making
extensive use of technologies like XML and SOAP.
In  addition to helping  write applications  that conform  to accepted
standards -  meaning our  applications have a  better chance  of being
able to interoperate  with other applications over the  Internet - the
CLR itself is an implementation of a standard. Microsoft has submitted
the CLI - the Common Language Infrastructure - to ECMA. The CLI is the
specification   that  describes   the  CLR.   It  can   be   found  at

What is in Mono? 

Common Language Infrastructure (CLI) virtual machine
Class loader 
Just-in-time compiler
Garbage collecting runtime 
Class library that can work with any language which works on the CLR. 
.NET compatible class libraries
Mono-provided class libraries 
Compiler for the C# language

Note: Other compilers that target the CLR in the future Mono Platform
support Just In Time (JIT) compiler for x86 systems;

Windows (XP/NT core)
Interpreter (slower)
Mono Assemblies
System, System.XML, System.Security 
Various other database providers. 
System.Web, System.Web.Service

Mono Development Tools:
mcs : Mono C# compiler
mbas : Mono Basic (supserset of VB.NET) compiler
mono : Mono Just-in-Time and Ahead-of-Time code generator 
mint - Mono interpreter
wsdl : WSDL utility
Generates web service client proxy and service from WSDL document. 
Other command line tools and utilities

How do I get Mono?

Available downloads:

Fedora Core 1
(Current release is 0.30.1)
