10.2 Application termination

10.2 Application termination
Application termination returns control to the execution environment.
C# LANGUAGE SPECIFICATION
70
If the return type of the application.s entry point method is int, the value
returned serves as the
application’s termination status code. The purpose of this code is to
allow communication of success or
failure to the execution environment.
If the return type of the entry point method is void, reaching the right
brace (}) which terminates that
method, or executing a return statement that has no expression, results in
a termination status code of 0.
Prior to an application.s termination, destructors for all of its objects
that have not yet been garbage
collected are called, unless such cleanup has been suppressed (by a call to
the library method
GC.SuppressFinalize, for example).
