The .NET Framework includes a set of standard class libraries. The class library is set in terms of a hierarchy of namespaces. Most of the worked up in APIs are part of either System or Microsoft namespaces. These class libraries execute a large number of general functions, such as file reading and writing, graphic rendering, database interaction, and XML document manipulation, among others. The .NET class libraries are obtainable to all .NET languages. The .NET Framework class library is alienated into two parts: the Base Class Library and the Framework Class Library. Base Class Library (BCL): The Base Class Library (BCL) consists of a small subset of the entire class library and is the core set of classes that serve as the essential API of the Common Language Runtime.[10] The classes in mscorlib.dll and a few of the classes in System.dll and System.core.dll are considered to be a division of the BCL. The BCL classes are accessible in both .NET Framework as well as its substitute implementations counting .NET Compact Framework, Microsoft Silverlight and Mono. Framework Class Library (FCL): The Framework Class Library (FCL) is a superset of the BCL classes and indicates the whole class library that ships with .NET Framework. It includes an extended set of libraries, including WinForms, ADO.NET, ASP.NET, Language Integrated Query, Windows Presentation Foundation, Windows Communication Foundation among others. The FCL is much superior in scope than standard libraries for languages likeC++, and comparable in capacity to the standard libraries of Java. The Base Class Library (BCL) is a regular library available to all languages with the .NET Framework. .NET comprise the BCL in order to summarize a large number of ordinary functions, such as file reading and writing, graphic rendering, database interaction, and XML document manipulation, making easy the programmer's job. It is much better in scope than standard libraries for the majority other languages, together with C++, and would be similar in scope to the standard libraries of Java. The BCL is sometimes wrongly referred to as the Framework Class Library (FCL), which is a superset as well as the Microsoft.* namespaces. The BCL is modernized with every version of the .NET Framework Namespaces Some of the namespaces might or might not be officially considered part of the BCL by Microsoft, but all are incorporated as part of the libraries that are equipped with Microsoft's implementation of the .NET Framework. Standardized namespaces These are the namespaces that are uniform as of the ECMA 335 and ISO/IEC 23271:2006 standards. System This namespace comprises the central requirements for programming. It includes base types like String, DateTime, Boolean, and so forth, sustenance for environments such as the console, math functions, and base classes for attributes, exceptions, and arrays. System Collections It re-defines numerous common containers or collections used in programming, like lists, queues, stacks, hashtables, and dictionaries. It comprises a prop up for generics. System Diagnostics It offers you the skill to diagnose your application. It consists of event logging, presentation counters, tracing, and interaction with system processes.
