Nuget package installation failure
<p>When trying to install a package from our newly created private Nuget Feed i get the following error.</p>

<p>Could not install package 'GC.Timecode 1.0.0.3'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.5.1', but the package does not contain any assembly references or content files that are compatible with that framework. </p>

<p>The Nuget package also targets 4.5.1. (Screenshot take from Nuget Package Explorer)</p>

<p>The Nuget Package is created by Octopack via On premises TFS, and then published to a private Proget Server</p>

<p>Nuspec file looks like this</p>

<pre><code>&lt;?xml version="1.0"?&gt;
&lt;package xmlns="http://schemas.microsoft.com/packaging/2010/07/nuspec.xsd"&gt;
&lt;metadata&gt;
&lt;id&gt;GC.Timecode&lt;/id&gt;
&lt;version&gt;1.0.0.3&lt;/version&gt;
