.NET base
classes – many of them, for math,
database access, windows applications,
web applications, etc, etc
Namespaces – named heirarchically; all under System (e.g., Now gives current date and time; it is in System.DateTime.)
Main method
always runs first.
Variables
are strongly typed: Given one type
in a declaration and keep that type (e.g.
ticks [long] must be separate from result
[double])
