I have verified from our issue tracking system and regret to share that at present the support for .NET Core is unavailable in Aspose.Slides and shall tentatively be available during 2018. You are right about fact that there is no System.Drawing in .NET Core and Aspose.Slides for .NET internally rely on that. For this reason, the support for .NET Core in Aspose.Slides for .NET is going to take some time to implement. An issue with ID SLIDESNET-37572 has already been logged in our issue tracking system to provide requested support. This thread has been linked with the issue so that you may be automatically notified once the support will be available.
