The .NET Framework class library is a
collection of reusable types that tightly integrate with the common language
runtime. The class library is object oriented, providing types from which your
own managed code can derive functionality. This not only makes the .NET
Framework types easy to use, but also reduces the time associated with learning
new
Features of the .NET Framework. In
addition, third-party components can integrate seamlessly with classes in the
.NET Framework.
