Namespaces in C# are used to organize classes.To access the class of a namespace, we need to use namespacename.classname. namespace is designed for providing a way to keep one set of names separate from another. The class names declared in one namespace does not conflict with the same class names declared in another. To define a namespace we need to use "namespace". eg.   namespace NamespaceName  {       class className      {      }  }   namespace WpfWorld Namespace  {       class WpfWorld      {      }  } if we want to use  WpfWorld class in another class then we have to add  WpfWorld Namespace to that class by using Keyword. using  WpfWorld Namespace;   namespace Ex Namespace  {       class Ex      {        var obj WpfWorld = new  WpfWorld();      }  }

Sealed class is a class that prevents the class from being inherited by other class.Sealed class can have Sealed Methods.Sealed method can't be override.To create a Sealed class we need to add Sealed modifier before class keywords. eg. sealed class MySealedClass { } Sealed class can be a derived class but can't be a base class.A sealed class cannot be an abstract class. Because abstract class has to provide functionality and here we are restricting it to inherit. One of the best usage of sealed classes is when you have a class with static members.

C# is used for many reasons, but the benefits of the Microsoft CLR tool set and a large developer community are two main draws to the language. C# is one of several programming languages that target the Microsoft CLR , which automatically gives it the benefits of cross-language integration and exception handling, enhanced security , a simplified model for component interaction, and debugging and profiling services. The strict type checking in C#, both at compile and run times, results in the majority of typical C# programming errors being reported as early as possible.In C# programming, however, that decision is made by the programmer who wrote the object, not by the programmer who instantiates the object and assigns it to a variable.

C++ and C# are two completely different languages, despite similarities in name and syntax. C# was designed to be somewhat higher-level than C++, and the two languages also take different approaches to details like who determines whether a parameter is passed by reference or by value.
