  <p>One situation resulting in this error has already been posted here at Stackoverflow, but <a href="https://stackoverflow.com/questions/12782863/the-error-this-project-is-incompatible-with-the-current-version-of-visual-studi">that question</a> has been closed. I'm thinking it's a fairly generic problem. Since I have found a "solution", I'll post this question, and my solution as an answer. </p>
