title: EF Core 2.0 Migration - dotnet ef migrations 'script' command outputting blank file
body: <p>I have recently migrated my web project to Asp.Net Core 2.0 and Entity Framework Core 2.0.</p>
  
  <p>The web application is working correctly and all dotnet ef migrations CLI commands are working apart from the following:</p>
  
  <pre><code>dotnet ef migrations script {migrationname1} {migrationname1} -o my-file-name.sql
  </code></pre>
  
  <p>The query appears to run with no errors and then produces no SQL code either to screen or file.</p>
  
  <p>I am using Visual Studio 2017 with SQL Server Express (localdb) on Windows.</p>
  
  <p>Just wondering if anyone else has come across the issue since migrating?</p>
  
  <p>Would appreciate some help as can not find anything on here or Google.</p>
