Visual Studio: The Operation could not be completed. The parameter is incorrect
<p>I have been working on a new solution all evening. Building without an issue, however all of a sudden I have started to get the following error when building: </p>

<blockquote>
  <p>The Operation could not be completed. The parameter is incorrect.</p>
</blockquote>

<p>Now, I have searched many threads, but I am yet to find a decent solution. I should also mention. I have restarted, tried to repair my VS 2015 Express install with no luck. </p>

<p>This is happening on EVERY solution, not just my new one, even if I close everything, start a brand new project and try and build. </p>

<p>Any suggestions would be welcome!</p>
