title: Add-Migration command only prompt "ScriptHalted"
body: <p>I'm trying to learn how to make App.Net Core application using Razor pages, using this tutorial : <a href="https://docs.microsoft.com/en-us/aspnet/core/tutorials/razor-pages/model?view=aspnetcore-3.0&amp;tabs=visual-studio" rel="noreferrer">https://docs.microsoft.com/en-us/aspnet/core/tutorials/razor-pages/model?view=aspnetcore-3.0&amp;tabs=visual-studio</a></p>
  
  <p>After I made the Movie model and scaffold it successfully, I try to make the initial migration of the database.</p>
  
  <p>However, every time I'm using the command <code>Add-Migration</code>, it just prompts <code>ScriptHalted</code>, even when using the verbose option, same with <code>Update-Database</code>.</p>
  
  <p>I tried other commands like <code>Enable-Migration</code> and they seems to work, but not the two I need.</p>
  
  <p>Is there anything that I'm missing ? </p>
  
  <p>It seems to me that I followed the tutorial perfectly, and tried to find an answer here, yet I didn't come up with any solutions.</p>
