# Class Library

[Class Library](https://www.mindstick.com/forum/158577/what-is-the-significance-of-the-base-class-library-bcl-in-the-dot-net-framework):The .Net Framework class library is a collection of reusable types that tightlyintegrate with the [common language runtime](https://www.mindstick.com/articles/16/common-language-runtime). The class library is [object oriented](https://www.mindstick.com/forum/162/object-oriented-programming-oop-s),providing types from which you own [manage code](https://answers.mindstick.com/qa/115277/how-does-version-control-software-help-developers-manage-code-changes-and-team-collaboration) can derive functionaly.This not onlymakes the .NET Framework type easy to use, but also reduces the time associatedwith learning new features of .Net Framework. In addition, third partycomponents can integrate seamlessly with classes in the .Net Framework.

Including task such as

* String Management

*[Data collection](https://answers.mindstick.com/qa/105129/how-to-use-mobile-devices-for-data-collection-in-business)

*[Database connectivity](https://www.mindstick.com/blog/462/database-connectivity-in-c-sharp)

*And [file access](https://www.mindstick.com/forum/157674/what-are-file-types-and-file-access-in-operating-systems)

The .net Framework class library is a library of classes,and, [interfaces](https://www.mindstick.com/articles/12100/interfaces-in-java-real-life-example), and values, and types that are included in the Microsoft.Netframe work SDK. This library provides access to system [functionality](https://www.mindstick.com/blog/136/using-watermark-functionality-in-textbox-by-jquery) and isdesigned to be the foundation on which .Net Framework [applications](https://www.mindstick.com/articles/12847/how-to-choose-the-right-ethernet-cable-for-industrial-applications), components,and controls are built.
