What are assemblies ? How does one use assemblies in a VB.net project ?

Assemblies are used to specify a logical unit or building block for .net applications. A .net application contains one or more assemblies. Every assembly has version properties that include a major and a minor version, revision as well as a build number. Thus all elements of an assembly are versioned as a unit. The specifications in an assembly are referred as the assembly’s manifest.
To use an assembly in VB.Net project one has to follow two steps:
- Add a reference of the assembly to the project. A default assembly containing the System namespace is by default added to the project.
Access the members or members of the namespace in the assembly using the fully qualified class name.
