Hello and welcome to this lecture.

2
00:00:02,970 --> 00:00:16,170
What is dot net not net is also pronounced as dot net the net is a software framework developed by Microsoft

3
00:00:17,730 --> 00:00:31,830
it mainly runs on Windows based platforms it includes a large core US library referred to as framework

4
00:00:32,010 --> 00:00:46,390
class library or FCO it also allows other languages to use code using by each other solely to allow

5
00:00:46,930 --> 00:00:51,120
code from other languages to be used by other languages.

6
00:00:51,110 --> 00:00:52,340
If you know what I mean.

7
00:00:52,360 --> 00:00:58,600
So allow each language to use code written in other languages.

8
00:00:58,600 --> 00:01:10,060
Also programs that are written in the Dot Net framework execute in a virtual software environment referred

9
00:01:10,060 --> 00:01:16,460
to as Common Language Runtime or C L R for short.

10
00:01:16,870 --> 00:01:24,790
So programs written in dot net will execute in a virtual execution environment known as Common Language

11
00:01:24,880 --> 00:01:31,940
Runtime or C R the F seal is quite useful.

12
00:01:32,320 --> 00:01:43,960
He provides user interface and data access database connectivity cryptography web application development

13
00:01:44,530 --> 00:01:56,530
numeric algorithms networked communications and so on are provided via the framework class library.

14
00:01:56,600 --> 00:02:05,900
This is a very basic diagram of the dot net architecture so it uses various languages.

15
00:02:05,900 --> 00:02:15,410
For example you can use the Visual Basic C sharp JS grip dot net and some the other languages that can

16
00:02:15,410 --> 00:02:18,900
be used with the dot net framework.

17
00:02:18,920 --> 00:02:23,800
So the common language specifications and these are the ones above him.

18
00:02:24,230 --> 00:02:30,890
And then you've got a common type of system and then you've got the Dot Net framework class library

19
00:02:30,930 --> 00:02:33,360
which we talked about earlier.

20
00:02:34,080 --> 00:02:39,050
So there are different components of the Dot Net framework.

21
00:02:39,050 --> 00:02:46,240
For example if you wanted to build web based applications you'd be using air speed dot net.

22
00:02:46,250 --> 00:02:54,700
Part of that of the framework which you can use to build forms ex email and web services.

23
00:02:55,070 --> 00:03:04,070
You can also build windows form and console based applications if you want to connect to databases or

24
00:03:04,070 --> 00:03:06,740
build data related projects.

25
00:03:06,770 --> 00:03:13,460
The idea that net component of the framework can also help you achieve that if you want to do remote

26
00:03:13,460 --> 00:03:17,820
network stuff they don't need remote and will help you.

27
00:03:18,070 --> 00:03:27,300
A Common Language Runtime This is where it executes the code in its own virtual environment.

28
00:03:27,360 --> 00:03:30,170
And this is just the operating system.

29
00:03:30,470 --> 00:03:38,050
So this is just a very basic illustration of the Dot Net framework.

30
00:03:38,840 --> 00:03:46,970
So the framework is language independent so you can work with many languages like C sharp visual basic

31
00:03:47,560 --> 00:03:49,790
js scripts and many more.
