How to Edit Bookmarks in a Word Document using Universal Windows App

I am building a Universal Windows application(UWP) which need to the add text to the bookmarks in a Microsoft Word Document.

I added the library Microsoft.Office.Interop.Word and included the below code that can add text to the bookmarks:

Microsoft.Office.Interop.Word.Application oWord = new Microsoft.Office.Interop.Word.Application();

Microsoft.Office.Interop.Word.Document oDoc;

object oTemplate = filepath;

oDoc = oWord.Documents.Add(ref oTemplate, ref oMissing, ref oMissing, ref oMissing);

oDoc.Bookmarks["BookmarkName"].Range.Text = "BookmarkText";

Error Message:

System.IO.FileLoadException HResult=0x80131515 Message=Could not load file or assembly 'Microsoft.Office.Interop.Word, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c'.
