title: .net standard class library - not support Distributed Transaction error
body: <p>I developed a logging service in .net standard class library project. It is perfectly working without <strong>System.Transaction</strong> <em>(TransactionScope class)</em>. 
  <br>When I add transaction to a process, logger insert method throws an exception. 
  [<strong>This platform does not support distributed transactions.</strong>]</p>
  
  <p>When I add code to core console app with System.Transaction it works. </p>
  
  <p>Is <strong>.net standard</strong> not supporting System.Transaction(TransactionScope)? </p>
  
  <p><strong><em>NOTE:</em></strong> 
  For now : .net core and nugets are lastest. </p>
  
  <ul>
  <li>Distribution Transaction Coordinator service is working,  </li>
  <li>EF Core version: 2.1.0 preview2-final,</li>
  <li>Class library versions .NET Standard 2.0  </li>
  <li>AspNetCore 2.0.5</li>
  </ul>
  
  <p><strong><em>Edit:</em></strong> 
  <br/>
  I realized that exception throws when I try to open second connection in same database with in the same TransactionScope block.
