Well, no, you won't.

There are a few reasons for that:
1) It's a console app. That means that it doesn't have a Graphical User Interface, it has a text based interface. Console Apps don't show lines, or circles, or buttons, or anything other than text. Try a WinForms application instead.

2) It's a point. I.e. it is a position in a space. A map reference if you like. It doesn't have anything to display. If I send a letter to you house (addressing a point on the planet surface) that does not automatically paint your house red!

A point does not have a size, so it can't be seen - you need to (for example) draw a line between two points!

Create a Winforms apps, and in your form design window, look at the Properties pane. Select the "Events" button - it looks like a lightning bolt - and scroll through to the Paint event. double click it and add this code to the handler routine when it appears as code:

C#

Pen red = new Pen(Color.Red, 3);
Point p1 = new Point(100, 100);
Point p2 = new Point(200, 200);
e.Graphics.DrawLine(red, p1, p2);
red.Dispose();

Now when you run your application, it will draw a red line, three pixels wide, diagonally on your form.

Yo have just defined a new point, you're not placing it anywhere.

In order to actually draw something I think you're trying to use a Windows Forms application where you would have a form where to draw, for example a line (see the example: http://msdn.microsoft.com/en-us/library/system.drawing.point.aspx[^])
