Creating a UWP application with MVVM Light and PCL

I'm starting a Windows UWP project using MVVM and it was my intention to put my ViewModels into a PCL project so that I can make use of Mocking when writing unit tests. However I'm used to using MVVM Light framework and it seems that it is no longer supporting PCL projects. If I want to continue creating my ViewModels in a PCL project in the future, will I have to go without MVVM Light or would it be recommended not use a PCL (and thus Mocking in my Unit tests)?
