What is the .NET Framework? - .NET Class Library
(Page 3 of 6 )
.NET comes with thousands of classes to perform all important and not-so-important operations. Its library is completely object oriented, providing around 5000 classes to perform just about everything.
The following are the main areas that are covered by Class library.
- Data Structures
- IO management
- Windows and Web Controls
- Database access
- Multithreading
- Remoting
- Reflections
The above list is comprehensive and only to provide you an instant idea regarding how comprehensive the library is.
The most fascinating part of .NET is the class library; it's common to all language of .NET. That means the way you access files in VB.NET will be exactly same in C#, and in fact all other languages of .NET. You learn library only for once, but use it in every language.
Also the library is common for all types of applications. The following are different types of applications that can make use of .NET class library.
- Console applications.
- Windows GUI applications.
- ASP.NET applications – web applications.
- XML Web services.
- Windows services.
So, you can leverage your knowledge of library irrespective of language and type of application you are developing. I think it is the best thing that can happen to programmers. Imagine moving from COBOL to C and then from C to VB. You learned how to perform common operations three times because those three languages didn’t have any function in common.
