Using the example provided in codeproject I am struggling to work out where I can find the reference to the library Microsoft.Office.Core.
I am getting the error \"
None of the above answer helped me, i was using Visual Studio 2017. What I did is, installed Office/SharePoint Development using Visual Studio Installer.
After that, I was able to see 'office', this assembly contains Microsoft.Office.Core.
Hope this helps you.
