title: cannot add reference to .net core Class library asp.net core rc2
body: <p>I am a newbie in the asp.net net core world and I am struggling to adding a simple ref .
  I get an error </p>
  
  <p>Steps</p>
  
  <p>1) Created an "Asp.net Core Web Application(Net Framework)  RC2"</p>
  
  <p>2) Added a Class Library (.Net core) called "ClassLibrary1")</p>
  
  <p>3)Within the web app.Project.json i added a reference to the classlibrary1 like this</p>
  
  <p>"dependencies": {
      "ClassLibrary1": "1.0.0-*", etc...</p>
  
  <p>4) Get error </p>
  
  <p>Severity    Code    Description Project File    Line    Suppression State
  Error   </p>
  
  <p>NU1001  The dependency ClassLibrary1 could not be resolved. </p>
  
  <p>I understand why microsoft is doing this as they want to be lean and modular,however 
  there should be an option that would add the reference for you like in the classic library.It's a step back in my view.</p>
  
  <p>Is this a bug or its me?</p>
  
  <p>thanks for any reply</p>
