title: Updating nuget packages in all projects in a solution
body: <p>I have a .net solution (say A) with multiple projects(say B,C,D). I want to update all nuget packages for all projects in the solution. I know I can update nuget packages using command line but passing in the path to packages.config </p>
  
  <pre><code>nuget update A/B/packages.config
  </code></pre>
  
  <p>Is there a way to update packages for all packages.configs inside folder A using command line without having to specify them individually? (I know this can be done from inside visual studio.)
  Something like </p>
  
  <pre><code>nuget update A/*/packages.config
  </code></pre>
