Metro.Mahapps Designer not showing

Question

Hi I've been struggling with this bug and I have no clue how to resolve this.

Basically the form designer giving me this error:

Error   2   Could not load file or assembly 'MahApps.Metro, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

But the application can compile.

xmlns:Controls="http://metro.mahapps.com/winfx/xaml/controls"
