Application.Run or not?

[Erik Cruz]

Hi.

Is there any benefits of using Application.Run in a Sub Main procedure to
start a windows application? I set a form as the startup object for all my
vb programs, but have seen several examples that starts an application by
using Application.Run in a Sub Main instead of define a form as the startup
object.

TIA,
Erik Cruz

Whenever you set a form as the startup object, VB.NET creates an invisible
Sub Main that looks like this one:

shared sub main
application.run(new Form1())
end sub

Application.Run contains a message loop that processes the messages sent to
the application. This default Sub Main can be used if there is no code to be
executed before or after showing the main form, and if the Form is displayed
from the start til the end of the application.

In addition to Armin's reply, have a look at the IL code of both
applications using "ildasm.exe".
