Warning 1 A reference was created to embedded interop assembly 'c:\Program Files\Reference Assemblies\Microsoft\VSTO40\v4.0.Framework\Microsoft.Office.Tools.Common.dll' because of an indirect reference to that assembly created by assembly 'c:\Program Files\Reference Assemblies\Microsoft\VSTO40\v4.0.Framework\Microsoft.Office.Tools.Word.dll'. Consider changing the 'Embed Interop Types' property on either assembly.
Developers get this is common warning during developing add-in for Microsoft Office. Because the type equivalence feature is not enabled by default in a office project. To enable this feature go to properties of
-- Microsoft.Office.Tools.Common
-- Microsoft.Office.Tools
-- Microsoft.Office.Tools.Word
-- Microsoft.Office.Tools.Excel
-- Microsoft.Office.Tools.Outlook - references and
set "True" to "Embed Interop Types" property.
The type equivalence feature, embeds type information to the office solution. And enables the version independence at run time
