I've added the PDFClown nuget package to a .net core project and ran into the following error at runtime:
Could not load file or assembly 'PDFClown, Version=0.1.2.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. A strongly-named assembly is required. (Exception from HRESULT: 0x80131044)
I'll also note that it build without issue and the problem only appears at runtime.
