.NET Categorization Application – a software program that runs (executes) on a computer. Project – a set of files (e.g. VB.NET source code, graphic files, Icon files) that are used to build an Application. Namespace - Namespaces organize the objects defined in an assembly

Assemblies For a.Net application assemblies form the fundamental unit of –Deployment –Version control –Reuse –Activation scoping –Security permission Assemblies take the form of –an executable (.exe) file or –a dynamic link library (.dll) file Assemblies provide the common language runtime with the information it needs to be aware of type implementations. Assemblies are different from.exe or.dll files because they contain all the information you would find in a type library, plus information about everything else necessary to use the application or component. They are similar to Project References in VB6.
