Missing Assembly Reference for OfficeMergeControlException
<p>When I try to use the code to combine multiple .docx files (the first listing at: <a href="http://stackoverflow.com/questions/247666/how-can-i-programatically-use-c-sharp-to-append-multiple-docx-files-together">How can I programatically use C# to append multiple DOCX files together?</a>), I seem to be missing an assembly reference for OfficeMergeControlException. </p>

<p>I'm using .NET Framework 4. </p>

<p>Thanks,
