So, an object encapsulates all the features, like data and behavior which are related to a class. OOP permits developers to develop modular programs and accumulate them as software. Objects are utilized to access data and behaviors of dissimilar software modules, like sharable assemblies, classes and namespaces. .NET Framework supports barely OOP languages, like Visual Basic, Visual C++, .NET, Visual C#.
