How to import .mgfxo effects file to project? [solved]

EDIT: These tutorials solved my problem:

I’m trying to learn from this tutorial and to continue I learned that I must convert this effects file to .mgfxo to make it work with MonoGame. I’ve converted the file with 2MGFX but what do I do with it now?

I have this code in LoadContent():

effect = Content.Load<Effect> ("effects");

this in Draw()

effect.CurrentTechnique = effect.Techniques["Pretransformed"];
            foreach (EffectPass pass in effect.CurrentTechnique.Passes)
            {
                pass.Apply();
            }

and have added effects.mgfxo to my project’s Content folder as I would’ve done with a .fx file.

and when I try to run it I get this error:

An unhandled exception of type 'Microsoft.Xna.Framework.Content.ContentLoadException' occurred in MonoGame.Framework.dll
Additional information: Could not load effects asset as a non-content file!
