我决定用 MonoGame 开始游戏开发，但我遇到了一个问题。

当我尝试使用 SpriteBatch 对象将精灵添加到屏幕上时，就像我在许多 XNA 教程中看到的那样，我得到了一个 OpenTK.Graphics.GraphicsErrorException。

    protected override void Draw (GameTime gameTime)
    {
        graphics.GraphicsDevice.Clear (Color.CornflowerBlue);

        spriteBatch.Begin();
        spriteBatch.Draw(spriteTexture, position, Color.White);
        spriteBatch.End(); // <—— Exception here

        base.Draw (gameTime);
    }

Exception.Message 说InvalidEnum。

就像这是非常基本的东西，我不知道我是否错过了什么……</p>

我在最新的 ArchLinux 安装下使用来自 MonoDevelop 的 MonoGame 版本 2.5.10。Mono 版本是 2.10.8，OpenTK 版本是最新的稳定版本（2010.10.06）。
