 <p>Apparently, emptying the ReSharper cache:</p> <blockquote> <p>In menu, ReSharper > Options > Environment > General > Clear Caches</p> </blockquote> <p>and disabling and re-enabling ReSharper:</p> <blockquote> <p>In menu, Tools > Options > ReSharper > General > Suspend / Restore</p> </blockquote> <p>did the trick for me. I am not sure if both operations are necessary, but they solved my problem.</p>
