Hi Hardik Normal 0 Namespace is a logical naming scheme for group related types.Some class types that logically belong together they can be put into a common namespace. They prevent namespace collisions and they provide scoping. They are imported as using in C# or Imports in Visual Basic. It seems as if these directives specify a particular assembly but they don't. A namespace can span multiple assemblies and an assembly can define multiple namespaces. When the compiler needs the definition for a class type it tracks through each of the different imported namespaces to the type name and searches each referenced assembly until it is found. * An Assembly is a logical unit of code * Assembly physically exist as DLLs or EXEs * One assembly can contain one or more files * The constituent files can include any file types like image files text files etc. along with DLLs or EXEs * When you compile your source code by default the exe/dll generated is actually an assembly * Unless your code is bundled as assembly it can not be used in any other application * When you talk about version of a component you are actually talking about version of the assembly to which the component belongs. * Every assembly file contains information about itself. This information is called as Assembly Manifest. Thanks

Hi Namespace: • To structure the project into meaningful pieces • To distinguish classes with the same name Assembly: An assembly is a file that is automatically generated by the compiler upon successful compilation of every .NET application. It can be either a Dynamic Link Library or an executable file Know more here: http://stackoverflow.com/questions/5915033/use-of-namespaces-in-c-sharp http://www.c-sharpcorner.com/uploadfile/ggaganesh/workingwithnamespaces11082005070923am/workingwithnamespaces.aspx http://www.codeguru.com/columns/csharp_learning/article.php/c5845/C-FAQ-15--What-is-an-Assembly.htm

Namespace is logical separation of classes while assemble is a physical separation. You define namespace for classes using keywords namespace MyNamespace { } in an assemply and assembly is compiled into .dll file.
