errors where building project

[Qwertcool54]

when i trying building project, i got this errors:
The type or namespace name 'xna' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)
The type or namespace name 'Game' could not be found (are you missing a using directive or an assembly reference?)
The type or namespace name 'Game' could not be found (are you missing a using directive or an assembly reference?)
The type or namespace name 'GraphicsDeviceManager' could not be found (are you missing a using directive or an assembly reference?)
} expected

I think that instead of using Microsoft.Xna.Framework, you have to use Fna.Framework? Not sure but give it a try
