title: .Net Core 1.1 with ADAL: The dependency NetStandard.Library >= 1.6.0 could not be resolved
body: <p>I'm trying to use ActiveDirectory client on my <code>NetCore 1.1</code> project. Project restores fine, but doesn't build. When building I get an error <code>The dependency NetStandard.Library &gt;= 1.6.0 could not be resolved</code> that points to Microsoft.IdentityModel.Clients.ActiveDirectory</p>
  
  <p>Why can't this dependency be satisfied? Library used to work before upgrading from <code>NetCore 1.0.1</code></p>
  
  <p>Here is my project.json (which contains lot's of extra stuff trying to resolve the problem):</p>
