Hello,
we are developing webpart as sandboxed solutions in visual studio 2013 for sharepoint online. We use external dll library iTextSharp for reading and writing PDF. We have problem with activation of solution. Our error message is shown below.
Error validating assembly 'itextsharp.dll'.
This solution references prohibited type 'System.Reflection.BindingFlags' and cannot be used on this site collection.
Can anyone help?
thanks
