there is a library (.net-) for creating PowerPoint presentations (PPTX => OpenXML). For creating Excel worksheets, I like the ClosedXML-Library and like something similar for PowerPoint. I cannot and do not want to use Microsoft Interop because it is an ASP.NET web application.
Does anyone have experience creating PowerPoint-Slides in ASP.NET?
PS: I looked at Aspose , but found it to be a little expensive.
