this is a compiled object that offers functions for other objects to use.

An assembly is a collection of types and resources that are built to work together and form a logical unit of functionality. Assemblies take the form of executable (.exe) or dynamic link library (.dll) files, and are the building blocks of .NET applications.

A module is a logical collection of code within an Assembly. You can have multiple modules inside an Assembly, and each module can be written in different .NET languages (VS, as far as I'm aware, doesn't support creation of multi-module assemblies).

• Assemblies contain modules.
• Modules contain classes.
• Classes contain functions. You can access assemblies, modules, classes, functions, properties, fields etc all via reflection at runtime.

A .NET program consists of one or more assemblies.

version of an object like a .dll or .exe

version of the assembly - (it's a .net thing)

generally the version of the product that utilises the assemblies as an end user solution.

e.g.

product version is used to identify the version of the application you are using assembly version is used to identify the version of the assembly used by the product file version is used to identify the version of the file employed by the assembly
