I wanted to know what basic pattern a new bie should follow, which is easy to maintain and work on. Or Are there some frameworks we should use.

Mostly ASP.NET websites are developed using the code-behind page logic, or some develop interfaces implemented by the code-behind page and than pass the page instance to a controller or presenter.

Any help from Shabir or other members, Thanks.
