Monogame DirectX can't enable Anti Aliasing

I make a new project in Monogame with DirectX, run this example code and AntiAliasing does not enable. If I make an OpenGL project it enables correctly. Why is this happening ? How can i fix this ?

using System;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;

namespace GameName1 {
    public class Game1 : Game {
        GraphicsDeviceManager graphics;
        SpriteBatch spriteBatch;
        Texture2D texture;

        public Game1() : base() {
            graphics = new GraphicsDeviceManager(this);
            graphics.PreferredBackBufferWidth = 450;
            graphics.PreferredBackBufferHeight = 800;
            graphics.PreferMultiSampling = true;
            Content.RootDirectory = "Content";
        }
        protected override void LoadContent() {
            spriteBatch = new SpriteBatch(GraphicsDevice);
            texture = new Texture2D(spriteBatch.GraphicsDevice, 1, 1);
            texture.SetData<Color>(new Color[] { Color.White });
        }
        protected override void Draw(GameTime gameTime) {
            GraphicsDevice.Clear(Color.Black);

            Matrix skew = Matrix.Identity;
            skew.M12 = (float)Math.Tan((double)Math.PI / 16);

            spriteBatch.Begin(SpriteSortMode.Texture, null, null, null, null, null,
                skew * Matrix.CreateTranslation(200, 200, 0));
            spriteBatch.Draw(texture, new Vector2(200, -200), 
                new Rectangle(200, 200, 20, 500),  Color.White, 
                (float)Math.PI / 8, Vector2.Zero, 4f, SpriteEffects.None, 0);
            spriteBatch.End();
        }
    }
}

Why is Anti aliasing not enabling correctly in DirectX but it does on OpenGL ? You can copy and paste this code and see for yourself, the texture is made programmatically, there is no images.

Edit: I also can’t get it to work on android either

Issue related to this at the end of the post.

So what exactly is the solution there ? That post is massive. You are saying that is a known problem that has not been fixed by an official update ? The issue at the end of the post you showed me is still open.

I just remembered that post and yes looks like the issue is open so maybe of relevance?

i opened a bug report and i got the answer that for anti aliasing on directX they will need help from the community to implement it cause its basically not implemented yet. So maybe with directX12 that also gets implemented ? who knows. Also i hope it was implemented for android as well… its a huge deal for somes games
