body: <p>How can I check if nuget package with specific version exists in a specified package source (nuget server) using powershell or commandline outside visual studio?</p>
  
  <h2>Scenario:</h2>
  
  <p>I have private NuGet server where I want to push my own packages. I have automated creation of the packages during TFS build. What I miss is check, if the package was previously uploaded and published to the NuGet Server.</p>
