title: Unable to find manifest signing certificate in the certificate store
body: <p>I signed the assembly with my VSTO 4.0 word add-in with strong name key file <code>.snk</code> and tried to uncheck Sign the ClickOnce manifest but after rebuild it appears again. After I tried to delete lines for ClickOnce manifest in <code>.csproj</code>, <code>.pfx</code> manifest appears after every rebuild.</p>
  
  <p>Does anyone know solution to permanently delete temporary ClickOnce manifest?</p>
