title: Error with System.Data.SqlClient with .NET standard
body: <p>Please can someone tell me how to resolve this?</p>
  
  <p>I am using EF Core</p>
  
  <pre><code>Could not load file or assembly 'System.Data.SqlClient, Version=4.2.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
  </code></pre>
  
  <p>I have a .NET standard class library that is hosted within service fabric</p>
  
  <p>can this be resolved with assembly mappings?</p>
  
  <p>I have added the System.Data.SqlClient package to both the class library and the service host</p>
  
  <p>Does anyone have any ideas?</p>
