title: URL for NuGet packages in Visual Studio 2019
body: <p>Been working on another computer for several months. Recently, I did a <code>git pull</code> on another laptop which is not used very often. When I tried to build the solution, several projects failed due to missing NuGet packages.</p>
  <p>I tried restoring the packages but this failed. Packages <code>MSTest.TestFramework</code> and <code>MSTest.TestAdapter</code> in particular were out-of-date, so I cleared the NuGet cache in <code>Tools &gt; Options &gt; NuGet Package Manager &gt; Clear All NuGet Cache(s)</code>.</p>
  <p>But now when I right-click the project and <code>Manage Nuget Packages...</code>, no packages are displayed at all!</p>
  <p>Back in <code>Tools &gt; Options &gt; NuGet Package Manager &gt; Package Sources</code> only a single <code>Machine-wide package source</code> is listed, namely <code>Microsoft Visual Studio Offline Packages</code>. This points to a location on my location disk (&quot;C:\Program Files (x86)\Microsoft SDKs\NuGetPackages&quot;, currently an empty folder).</p>
  <p>New sources can be added, but what URL should be used to get the latest NuGet packages?</p>
