title: OmniSharp-VIM, OmniSharp-Roslyn, and dotnet core on Ubuntu 16.10 - Syntax checking not recognizing C# 6 and requires solution file
body: <p>I am trying to set up my Ubuntu machine for dotnet core development. I've painstakingly installed Omnisharp-vim and set it to work with the OmniSharp-Roslyn server. I also have Syntastic and YouCompleteMe installed. I am getting syntax checking and Intellisense. I have two problems though:</p>
  
  <ol>
  <li><p>Omnisharp-vim does not work without a solution file. Dotnet core projects don't have to have solutions files. How do I get around this?</p></li>
  <li><p>I am getting syntax error for valid C# 6 code. For instance, it does not recognize the nameof operator.</p></li>
  </ol>
