title: "The visual Studio component cache is out of date, please restart Visual Studio."
body: <p>I'm on windows 7, using Atmel studio 7.0. When I opened up my project in Atmel Studio, it failed to load and gave this error:</p>
  
  <pre><code>The Visual Studio component cache is out of date please restart visual studio.
  </code></pre>
  
  <p>When I closed and reopened Atmel Studio, the same error continued. I also tried right clicking on my project, and selecting "Reload project" but then I got this error:</p>
  
  <pre><code>Value cannot be null. Parameter name: url
  </code></pre>
  
  <p>How can I open up my project?</p>
