title: Unity can't load System.data.dll
body: <p>I've downloaded the last Unity (2018.1) and changed the scripting runtime version to 4.x. </p>
  
  <p>But I can't find which System.Data.dll I should include in my project (I need it for my System.Data.SQLite library).</p>
  
  <p>If I check in Unity's folders There are a lot of folders in MonoBleedingEdge/lib/mono : 4.0, 4.0-api, 4.5, 4.5.1-api ...</p>
  
  <p>I tried with a few System.Data.dll found in those folders</p>
  
  <p>I always get that "Loading script assembly "Assets/Plugins/System.Data.dll" failed!" when I run my game. Do you know why ? Or is there a possibility to have more details (like version of the dll expected)</p>
