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
Introduction:
-------------
.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).
Basics:
-------
Platform:
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.
Runtime:
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.
Libraries:
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
http://www.ecma.ch.
What is in Mono?
----------------
Common Language Infrastructure (CLI) virtual machine
Class loader
Just-in-time compiler
