Annoyed about what happen i spent a few hours tracking it down.
I had MonoGame 3.0.1 installed. When i downloaded the 3.2 windows installation file some or all of the DLL's for the framework where throwing the errors.
I did complete uninstall and re-installs but the 3.2 version never works.
Then i use the nuget package manager to install MonoGame, and everything worked perfectly.
I'm thinking the 3.2 package is corrupt, or there is a dependency required that i'm not installing when i use the win installation package.
