InnerException:
Here is the code I am using:
PresentationEx master = new PresentationEx(Server.MapPath("~/Content/Presentation/Designs/SoloFS_Hospitality.pptx"));
PresentationEx temp = new PresentationEx(Server.MapPath("~/Content/Presentation/Slides/Go To Market.pptx"));
MasterSlideEx masterSlide = master.Slides[1].LayoutSlide.MasterSlide;
int tempMasterIdx = temp.Masters.AddClone(masterSlide);
int slideIdx = temp.Slides.AddClone(temp.Slides.Count > 1 ? temp.Slides[1] : temp.Slides[0], temp.Masters[tempMasterIdx]);
I am using this code successfully for every other PPTX in my project but the attached.
