I really don't understand why does MonoGame not show - if I export fbx since MonoGame 3.7

Hello everyone,

I have tried to understand but why does it happen? box doesn't see in MonoGame.

I am sorry because I still learn more more.....

using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;

namespace MonoCrraft
{
    /// <summary>
    /// This is the main type for your game.
    /// </summary>
    public class Game1 : Game
    {
        GraphicsDeviceManager graphics;
        SpriteBatch spriteBatch;

        Model model;
        BasicEffect effect;

        public Game1()
        {
            graphics = new GraphicsDeviceManager(this);
            Content.RootDirectory = "Content";
        }

        protected override void Initialize()
        {
            base.Initialize();
        }

        protected override void LoadContent()
        {
            spriteBatch = new SpriteBatch(GraphicsDevice);

            model = Content.Load<Model>("box");
            effect = new BasicEffect(GraphicsDevice);
            effect.Projection = Matrix.CreatePerspectiveFieldOfView(MathHelper.PiOver4, GraphicsDevice.Viewport.AspectRatio, 1.0f, 100.0f);
            effect.View = Matrix.CreateLookAt(new Vector3(2, 3, 2), Vector3.Zero, Vector3.Up);
        }

        protected override void UnloadContent()
        {
            
        }

        protected override void Update(GameTime gameTime)
        {
            if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed || Keyboard.GetState().IsKeyDown(Keys.Escape))
                Exit();

            base.Update(gameTime);
        }

        /**
         *  Model and matrix
         */
        private Matrix GetParentTransform(Model m, ModelBone mb)
        {
            return (mb == m.Root) ? mb.Transform : mb.Transform * GetParentTransform(m, mb.Parent);
        }

        private void DrawModel(Model m, Matrix world, BasicEffect be)
        {
            foreach(ModelMesh mm in model.Meshes)
            {
                foreach(ModelMeshPart mmp in mm.MeshParts)
                {
                    be.World = GetParentTransform(m, mm.ParentBone) * world;
                    GraphicsDevice.SetVertexBuffer(mmp.VertexBuffer, mmp.VertexOffset);
                    GraphicsDevice.Indices = mmp.IndexBuffer;
                    be.CurrentTechnique.Passes[0].Apply();
                    GraphicsDevice.DrawIndexedPrimitives(PrimitiveType.TriangleList, 0, 0, mmp.NumVertices, mmp.StartIndex, mmp.PrimitiveCount);
                }
            }
        }

        protected override void Draw(GameTime gameTime)
        {
            GraphicsDevice.Clear(Color.CornflowerBlue);
            DrawModel(model, Matrix.Identity, effect);

            base.Draw(gameTime);
        }
    }
}

I already exported box.fbx from Blender 2.79x

Result: box doesn't show up.

I have tried to understand with tutorial

How do I fix if model doesn't show in Game.

// EDIT

It seems problem with MonoGame 3.7 because ContentException of fbx, dae, obj etc don't work.

I go back MonoGame 3.6 and it works fine.

Thanks!
