rendering 3D lines in C#

Hi,
 
for a little application of mine I want to draw a 'wireframe' of connected cubes like this:

(Sorry for my bad painting skills )
 
I'm looking for an easy 3d engine/class that can draw lines, circles or cubes or spheres and where you can move the camera position.
It doesn't have to be a perfect engine/class, even something that renders Graphics on a form will do, but I can't find any that do the full job.
 
I hope it is clear what I am looking for, and I hope someone can help me.
 
Does anyone know what I can use for this?
