title: Using Visual Studio Code and using defined symbols
body: <p>EDIT: I have edited the whole question, since this is not only for Unity3D, but at all .sln projects.</p>
  
  <p>I have a installation of Visual Studio Code(Not Visual Studio, but this:<a href="https://code.visualstudio.com/" rel="nofollow">https://code.visualstudio.com/</a>) on my Macbook at work. VSCode is otherwise working just fine with normal and Unity3D projects. I get Intellisense on all classes, including Unity3D specific ones, like GameObject. So I think my installation and startup sequence is correct.</p>
  
  <p>Only problem I have, is that VSCode does not seem to recognize constants defined in the .csproj files. First I noticed this with some Unity3D plugins, but it is persistent on normal Visual Studio projects too.</p>
  
  <p>My sample project is a dummy application downloaded from internet, but it is fully working on MonoDevelop. This is my code</p>
  
  <pre><code>using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Text;
  
  namespace DummyConsoleApplication
      {
      class Program
          {
              static void Main(string[] args)
              {
                  tester();
              }
  
              #if DEBUG
              static void tester(){
  
              }
              #endif
          }
      }
  </code></pre>
  
  <p>The function call in Main causes a not found exception on the editor, but it compiles fine, since the .csproj file has this line:</p>
  
  <pre><code>&lt;DefineConstants&gt;DEBUG;TRACE&lt;/DefineConstants&gt;
  </code></pre>
  
  <p>Any verification on if this is normal behaviour for VSCode would be greately appreciated. Also, if anyone is aware of any solution, even hacky ones, to get past this bug and force Intellisense to autocomplete would help out too.</p>
  
  <p>The error I get is:</p>
  
  <pre><code>The name 'tester' does not exist in the current context [DummyConsoleApplication]
  </code></pre>
  
  <p>My hardware is a Macbook with Yosemite and my compiler is dnx-mono.1.0.0-beta4.</p>
