This is simply the XNA Primitives Shapes project ported over to MonoGame. I updated the refrences to refrence the MonoGame framework and nothing more. I wrote none of this code.

This is the project page: http://jcpmcdonald.com/libraries/2d-xna-primitive-shapes/ and the bitbucket repository https://bitbucket.org/C3/2d-xna-primitives/wiki/Home .

Those sources hold documentation on how to use this library. I have found it very useful in my projects.
