PDFsharp & MigraDoc Foundation

I am using the MigraDoc ( WPF build ) dll's for generating a pdf and i have added the code given below that does the work of adding a new private font :

XPrivateFontCollection pfc = XPrivateFontCollection.Global;
Uri myuri = new Uri(Server.MapPath("/Assets/Rupee_Foradian.ttf"));
pfc.Add(myuri, "./#Rupee Foradian");

The pdf generates successfully with the font loading properly and displaying as expected, but when i try for the second time to create the pdf i get an ArgumentException: An entry with the specified family name already exists

Can anyone please help me out on this issue ?

Hey thanks for the answer, but can you please also show me how to go about adding it only once and not every time when the document is being generated ?
