These are 7 fundamentals ASP.NET interview questions for web developers including CLS, CTS, DDLs, OOP , .NET FrameWork Concepts and much more.
7 Pillars of ASP.NET:
When ASP.NET was first released, there were seven key facts that differentiated it from previous Microsoft products and competing platforms. If you’re coming to ASP.NET from another web development platform, or you’re an old-hand .NET coder who has yet to try programming for the Web, these sections will quickly give you a bit of ASP.NET insight.
1: ASP.NET is integrated with the .NET Framework
The .NET Framework is divided into an almost painstaking collection of functional parts, with tens of thousands of types (the .NET term for classes, structures, interfaces, and other core programming ingredients).
2: ASP.NET is Compiled, Not Interpreted
ASP.NET applications, like all .NET applications, are always compiled. In fact, it’s impossible to execute C# or Visual Basic code without it being compiled first.
3: ASP.NET is Multilanguage
No matter what language you use, the code is compiled into MSIL. MSIL is a stepping stone for every managed application.
4: ASP.NET is Hosted by the Common Language Runtime
Perhaps the most important aspect of the ASP.NET engine is that it runs inside the runtime environment of the CLR. The whole of the .NET Framework—that is, all namespaces, applications, and classes—is referred to as managed code. Basic features of CLR are:
A) Automatic memory management and garbage collection
B) Type safety
C) Extensible metadata
D) Structured error handling
5: ASP.NET is Object-Oriented
ASP.NET is truly object oriented. Not only does your code have full access to all objects in the .NET Framework, but you can also exploit all the conventions of an OOP (object-oriented programming) environment.
6: ASP.NET supports all Browsers
ASP.NET addresses the problem of cross browser compatibility in a remarkably intelligent way. Although you can retrieve information about the client browser and its capabilities in an ASP.NET page, ASP.NET actually encourages developers to ignore these considerations and use a rich suite of web server controls. These server controls render their markup adaptively by taking the client’s capabilities into account.
7: ASP.NET is Easy to Deploy and Configure
Every installation of the .NET Framework provides the same core classes. As a result, deploying an ASP.NET application is relatively simple. For no-frills deployment, you simply need to copy all the files to a virtual directory on a production server (using an FTP program or even a command-line command like XCOPY).
