Hi Rikasa,
Thank you for contacting Syncfusion support.
Currently Essential Presentation doesn’t have any control to preview the PowerPoint Presentation document in ASP.NET Core platform. We have already logged this as a feature request in our database. We will implement this feature in any of our upcoming releases. We usually have an interval of at least three months between releases. The feature implementation would also greatly depend on the factors such as product design, code compatibility and complexity. We request you to visit our website periodically for feature related updates.
Regards,
Kumaravel
