title: dotnet run watch : Exited with error code 1
body: <p>I'm using an Angular C# app with asp.net-core-2.0. I added the dotnet watch library so when i make changes to my C# controller, my Angular app will be updated as well.</p>
  
  <p>I included this line in my <code>.csproj</code> file </p>
  
  <pre><code>&lt;ItemGroup&gt;
      &lt;DotNetCliToolReference Include="Microsoft.DotNet.Watcher.Tools" Version="2.0.0" /&gt;
  &lt;/ItemGroup&gt; 
  </code></pre>
  
  <p>When i make change to my C# controller, i get this error : <code>watch : Exited with error code 1</code> and my angular app is not updating since i need to refresh the browser manually to see the changes. Any idea why i have this error and how i can resolve it ?</p>
  
  <p>Thanks</p>
