title: Nuget Update-Package not finding new versions of packages
body: <p>I have a product with multiple services that have many solutions each. In order to reference things across services we are using Nuget to download and reference the dlls. Since we are still in early development of this product there are a lot of changes to the core dlls and we are having a lot of merging issues and annoyances with updating the references.</p>
  
  <p>I tried using Update-Package -ProjectName XProject -Safe thinking this would do exactly what I wanted it to, update all the references with the same Major/Minor version. However, it just skips over all the files saying they are updated. When I look in Nuget it clearly notices that there is a new version so I am unsure what the problem is...</p>
  
  <pre><code>No updates available for 'Framework.EntityModel'.
  No updates available for 'Framework.Core'.
  </code></pre>
  
  <p>in packages.config:</p>
  
  <pre><code>&lt;package id="Framework.Core" version="1.0.14030.1137" targetFramework="net45" /&gt;
  &lt;package id="Framework.EntityModel" version="1.0.14030.1137" targetFramework="net45" /&gt;
  </code></pre>
  
  <p>There are versions in nuget with the label: 1.0.14034.1137 so I don't know why it isn't picking them up. I can open up package manager and update from there fine. I just want a way to easily update every reference without doing things manually.</p>
