title: Publish error: The targeted framework not found
body: <p>I've got a strange dependency-related problem with asp.net core rc2.
  I can build + run my app locally without any problems.</p>
  
  <p>But as soon as I try to publish to azure (or even locally to any folder via dotnet publish) i get:</p>
  
  <pre><code>The targeted framework { 'Microsoft.NETCore.App': '1.0.0-rc3-004338' } was not found.
  - Check application dependencies and target a framework version installed at:
    C:\Program Files\dotnet\shared\Microsoft.NETCore.App
  - The following versions are installed:
    1.0.0-rc2-3002702
  - Alternatively, install the framework version '1.0.0-rc3-004338'.
  </code></pre>
  
  <p>As far as I can understand, some of my dependencies need this rc3 version? But how can I find the problematic one? And why is my app working on my dev machine?I'm lost here :(</p>
  
  <p>Any help welcome! Thank you :)</p>
