Is there a MessageBox equivalent in WPF?

Question

Is there a standard message box in WPF, like WinForms\' System.Windows.Forms.MessageBox.Show(), or should I use the WinForms message box?

Answer 1

In WPF it seems this code,

System.Windows.Forms.MessageBox.Show("Test");

is replaced with:

System.Windows.MessageBox.Show("Test");
