title: List all available versions of a specific package in NuGet Package Manager Console
body: <p>What NuGet PowerShell command will return a list of all versions of a specific package?</p>
  <p>I have tried the following, but it only returns one version of NUnit along with a number of other (un)related packages, each having only one version.</p>
  <pre><code>Get-Package -Source https://go.microsoft.com/fwlink/?LinkID=206669 -ListAvailable -Filter NUnit -AllVersions
  </code></pre>
  <p>Note: I specify the source URI because we have our own internal package source as our default remote.</p>
  <p>My understanding is that the <code>-AllVersions</code> switch <em>should</em> pull back every version of each matching package.</p>
  <p>I can't seem to figure out:</p>
  <ol>
  <li>Am I doing it wrong?</li>
  <li>If not, are project maintainers (or someone else) removing older versions from the package source?</li>
  <li>If they are, why?</li>
  </ol>
