title: Can't start Omnisharp because of mono version
body: <p>Whenever I start up VS Code on my Mac (Yosemite), I get the following error in VS Code</p>
  
  <p>Error: Cannot start Omnisharp because Mono version >=3.10.0 is required</p>
  
  <p>Any ideas?  I installed dnvm using homebrew exactly like the docs said at <a href="http://docs.asp.net/en/latest/getting-started/installing-on-mac.html" rel="noreferrer">http://docs.asp.net/en/latest/getting-started/installing-on-mac.html</a></p>
