Now i want show that contract in mobile application built with xamarin forms. We have a code to get the contract text from server. Its plain html content. Now i have ro modify a little bit before showing it to user. In order to mofidy i am trying to load the content in word document. When i call open menthod of word document object it is throing exception that docio does not support this format. Does anyone know what is the issue. I have added required dlls to xamarin pcl library.
