  11. VB.NET List of Objectives: • Let’s Get Started: • Create an application using VB.NET • Start getting familiar with all of the various functions in the IDE. • Use the Code Editor and Object Browser.

  12. VB.NET .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

  13. VB.NET 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.
