This section contains information about the core functionality provided by the common language runtime and the .NET Framework class library. The common language runtime is the foundation of the .NET Framework. It manages code at execution time, providing core services such as memory management, thread management, and remoting, while also enforcing strict type safety and other forms of code accuracy that promote security and robustness. The class library, the other main component of the .NET Framework, is a comprehensive, object-oriented collection of reusable types that you can use to develop managed applications. The topics in this section provide details about how to use the features offered by the .NET Framework.
