Missing dependency upgrading from 16.10 to 17.4


I am seeing the following error after upgrading from 16.10 .net4.0 to to 17.4 .net4.0:

System.IO.FileLoadException: Could not load file or assembly ‘Aspose.Slides.dll’ or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

I upgraded by downloading the Dll’s package for Aspose.Slides. I checked what was brought down by nuget as well, and that is only the Aspose.Slides.Dll and an xml file which I don’t believe is required…

Any thoughts appreciated as I’m completely stuck :slight_smile:

I just tried getting the assemblies via nuget (same version) and built against those. Now all OK…
