Difference: Website vs Web Application
So, now a question is what's the difference between a website and a web application?
ahhh..
Not a lot more or everything. It's mostly a matter of perspective and semantics and is largely opinion based.
In my perspective, generally a website is defined by its static content and web application is defined by its user interaction that requires programmatic user input or data processing.
The basic distinction would be if a website is connected with a database and stores user data or modifies what the user sees based on some user specified criteria, then it's probably a web application. Whereas on other hand, the static files such as .html that link pages to one another, I would say it's a website.
When you create a new project in Visual Studio, You'll see there are two options offering you to create a new project, one option is Website and another option is Web Application (New Project). So, you can select your option as per your requirements.
In my opinion, following are few points that practically differentiate both of them:
Web Site : -
1)A Website is Informational
2)All the files in folder structure are automatically included in the website. There is no .csproj/.vbproj project files in Website
3)When you deploy or publish Website, you need to upload both .aspx and .cs/.vb files to the server
4)By default explicit namespaces are not added to pages, controls or classes, but you can add them manually
5)There is no need to re-compile or built the website before publish or deployment
Web Application :-
1)A Web Application is Interactive
2)A Visual Studio .csproj/.vbproj project file stores information about the Web Application, such as list of included project files or any internal or external project to project references
3)When you deploy or publish Web Application, you only need to upload .aspx files and there is no need to upload .cs/.vb files because code-behind files are pre-compiled in .dll file
4)By default explicit namespaces are added to pages, controls and classes
5)You need to re-compile or built the web application before publish or deployment because it contains .dll files with reference of other project file details
Website vs Web Application – Which is best and appropriate?
As I explained above, when you want to create an Informational project, then go for Website and when you want to create an Interactive project that requires programmatic user input or data processing, and then go for Web Application.
