New Post: Portable Class Library + MVVM C# Store Application

I created a Portable Class Library and added the MVVM Light PCL to it.

PCL
--Model
----Term.cs

Term.cs contains a reference to GalaSoft.MvvmLight.

I also created a MVVM Store C# Application. I added a reference to the PCL above. However, when I build the project, I get the following errors:

Cannot resolve Assembly or Windows Metadata file 'GalaSoft.MvvmLight.dll'
Type universe cannot resolve assembly: GalaSoft.MvvmLight, Version=4.0.23.23876, Culture=neutral, PublicKeyToken=null

If I remove the model class (Term.cs), the MVVM C# Application builds successfully?

I will appreciate any assistance in resolving this
