            temporaryPresentation.SaveAs("Temporary", Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType.ppSaveAsPresentation, Microsoft.Office.Core.MsoTriState.msoTrue);

            temporaryPresentation.Close();

        }
        catch (COMException Ex)
        {
            Debug.WriteLine("Some problem" + Ex.Message + Ex.StackTrace);
            MessageBox.Show("PLease enter text ");
        }

    }

I think I got what you want. When pasting the new slide, save the new SlideRange. Afterwards assign the design of the source slide.

PowerPoint.Application ppApp = Globals.ThisAddIn.Application;
PowerPoint.SlideRange ppslr = ppApp.ActiveWindow.Selection.SlideRange;
string desktop = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
var temporaryPresentation = Globals.ThisAddIn.Application.Presentations.Add(Microsoft.Office.Core.MsoTriState.msoTrue);
Microsoft.Office.Interop.PowerPoint.CustomLayout customLayout = ppApp.ActivePresentation.SlideMaster.CustomLayouts[Microsoft.Office.Interop.PowerPoint.PpSlideLayout.ppLayoutText];

for (int i = 1; i <= ppslr.Count; i++)
{
    var sourceSlide = ppslr[i];
    sourceSlide.Copy();

    var design = sourceSlide.Design;                    
    SlideRange sr = temporaryPresentation.Slides.Paste(); // get newly created slideRange
    sr.Design = sourceSlide.Design; // manually set design
}
temporaryPresentation.SaveAs("Temporary", Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType.ppSaveAsPresentation, Microsoft.Office.Core.MsoTriState.msoTrue);
temporaryPresentation.Close();

It worked for me. Please let me know if this is the expected behaviour!
