Creating a Window object and then calling it in an other Window class in WPF C#

Question

Why this first code works

MessageBox.Show("No Applicants\nFirst Add applicants with dataentryaccount");
MainWindow mw = new MainWindow();
mw.Show();
this.Close();

But this second code doesn't show the mw window

    MessageBox.Show("No Applicants\nFirst Add applicants with dataentryaccount");
MainWindow mw = new MainWindow();
this.Close();
mw.Show();

Although when debugged Line by Line all these lines are executed.

because you are closing the `main` program window before you show next window — Olivarsham, Feb 27 '16 at 06:26
But When debugged Line by line, the lines do execute? How will you justify that — Syed Kumail Haider Naqvi, Feb 27 '16 at 06:31
Honestly - How aren't you getting an `ObjectDisposedException` in both examples. — Gabe, Feb 27 '16 at 06:49

The EventHandler or procedure of the current execution block has some more code to execute.
You have not called return to stop the execution of the current procedure.

Close() is just another function which will not delete the form immediately. So it continues the execution of the current code.

Please check this answer for more details.

Hmmm, So you mean that the new window would be created, But because of it having no more reference it will eventually be disposed by the garbage collector – Syed Kumail Haider Naqvi Feb 27 '16 at 07:12
