MVC pattern

Hi Manuel,
MVC is a design pattern to develop the ASP .Net web applications.
its the shorter form of Model View Controller
MVC defines as follows
" The pattern isolates "domain logic"(the application login for the user) from the user interface (input and presentation), permitting independent development,testing and maintenance of each"

According to MVC a program should be written in 3layers

Model: it represents the type that we want to access
View: which provides I/O to user
Controller: its the most important, which is responsible for handling all the tasks of application..

How MVC application will work

step1 : incoming request directed to controller

step2: controller process request and forms a datamodel

step3: model is passed to the view

step4: view transforms model into appropriate format

step5: reponse is rendered

Sample application :

pre requirements :

        Visual studio 2010 with its service pack1

        install the MVC3 template

1. start the VS &  select the ASP .Net MVC3 application template

2. go to Controller folder--> right click and add a new controller

3. write this method inside of the controller public string Welcome(string s){ return "Welcome "+s;}

4. right click on this method & select add view option to select the view & design the view according to ur wish

5. go to the browser http://localhost/controllername/welcome?s=CSharpCorner

6. now see the result

I hope you will satitsfy with this please reply me if you have any updates
