Modules are the .NET equivalent of dll and exe executable files, and
this feature can be used to create applications that are written from
a mixture of languages.
You can mix languages in .NET to create an application, however, this
isn't done through inline code. Instead, you have to do it by linking
together seperate projects written under different languages within
the same solution.
For example, suppose you wanted to write a VB.NET applilcation that
reads Microsoft Word files. Word files are implemented through
Microsoft's Structured Storage API which is available only as a C++
library. To use this API, you would write a Visual C++.NET project
that opens MS Word files, does a directory on them, reads them, and
closes them. You would expose methods in this C++ project that your
VB.NET project can call to retrieve the data that was read from the
Word files. You would add and compile both projects into a single
solution which inturn will produce an assembly.
The VB.NET project and the C++.Net project are considered to be
modules of this finished assembly.
