Overview 23
control structure (sequences, loops, and conditional statements) that implement our
protocol, and also provide data (such as IP addresses and port numbers) used by the
libraries.
When an application is compiled, it references the libraries it uses: the compiler
consults the library assemblies for information it needs. This command compiles
the Monitor application, which uses the Server and Temperature libraries.
csc /target:exe /reference:Server.dll,Temperature.dll Monitor.cs
In the .NET framework, an application is an assembly that contains a main
method. It has the file type exe. The application assembly does not contain the
compiled code of the libraries it uses.
