title: VS Code c# intellisense
body: <p>I have installed VS Code on my computer with Linux (ubuntu 16) and I have installed C# extension, but intellisense does't work. </p>
  
  <p>When I tried to find out solution in other sides, I found that I must open a <code>.sln</code> file. But I compile all scripts using command line and <code>.sln</code> file in most cases doesn't make sense for me. Is there any other way how to enable C# intellisense in VS Code when I open only <code>*.cs</code> files?</p>
