To be specific thats exactly what we are doing now. I have to admit my desription is not very specific... Normaly you use MonoGame with a GameWindow but we are using it inside a Console Application without any Windows. When we used XNA it was enough to inherit from Form to get access to the GPU but with MonoGame this doesn't work anymore.
class GPUMagic : Form
var target = new RenderTarget2D(deviceService.GraphicsDevice, TargetWidth, TargetHeight);
* Do Shader &Spritebatch Magic here
//Extract Bitmap from target
