title: Nuget in Visual Studio 2015 ignores allowedVersions?
body: <p>I have an MVC5 project that uses jQuery, included through Nuget package manager.<br>
  I want to keep the project on the 1.x branch.<br>
  This is done using the allowedVersions attribute in packages.config:</p>
  
  <pre><code>&lt;package id="jQuery" version="1.11.1" targetFramework="net45" allowedVersions="[1.10.2, 2.0.0)" /&gt;
  </code></pre>
  
  <p>Since I switched to VS 2015, this is ignored, Nuget suggests 2.1.4 (at the time of writing) as newer version.<br>
  Also tried variations like [1.10.2, 2) and [1.1, 2).<br>
  Is this a bug or a newer mechanism is used now to achieve this?</p>
