NuGet can't resolve a dependency when updating a local package with dependencies from online repositories using Visual Studio 2015 Update 1
<p>This is very similar to the issue in this question: <a href="https://stackoverflow.com/questions/4956633/local-nuget-package-dependencies-resolve-from-official-nuget-feed">Local NuGet package dependencies - resolve from official Nuget feed?</a></p>

<p>I have a local package whose latest update now has a dependency of <code>EnterpriseLibrary.TransientFaultHandling</code> from NuGet.org.  When I attempt to update the package, I get the following error:</p>

<blockquote>
  <p>Unable to resolve dependency
  'EnterpriseLibrary.TransientFaultHandling'. Source(s) used:
  'nuget.org', '(My Company)', 'Microsoft and .NET'.</p>
</blockquote>

<p>In VS 2013, it updates without any issue.  In VS 2015, as a workaround, I have to manually install the dependency and then I can do the update.</p>

<p>Am I missing something or is this just a bug in VS 2015?</p>
