UWP supporting Windows.Forms library

I'm working on a UWP project in which I'm trying to add a third-party library. I added the library and everything seemed to work fine until I cleaned and rebuild the solution? Now I'm getting: 

Cannot resolve Assembly or Windows Metadata file 'Type universe cannot resolve assembly: System.Windows.Forms ...  Project.csproj

and 

Could not copy the file "obj\x86\Debug\FavoriteControl\Favorite.xbf" because it was not found.

I definitely know that the errors are from the library. The library was added through Reference and some header were added inside the project.

Universal Windows Platform (UWP)

    Hello,

    Welcome to Microsoft Q&A!

    The libraries used by UWP projects are not fully compatible with WinForm, you cannot directly reference them. Please consider replacing with a library supported by UWP.

    Thank you.
