title: What's the difference between Version and Installed in NuGet GUI in Visual Studio?
body: <p>I've noticed that in Visual Studio's GUI for NuGet, the table showing which projects have a given package installed has the columns Version and Installed. Version always seems to either match what Installed says or is blank. For example, here's a screenshot after having just installed System.New.HttpJson to two projects.</p>

  <p>Why does the last project have both columns populated, but the project before it has nothing in the Version column?</p>
