title: How should I tell TeamCity's NuGet Installer build step to use both NuGet.org and the TeamCity provided packages source?
body: <p>I'm having trouble with my NuGet Installer build step.</p>
  
  <p>We're using both official NuGet.org packages and our own packages hosted on the TeamCity NuGet server. If I leave Packages Sources blank, then packages from nuget.org are found, but as soon as I specify <code>%teamcity.nuget.feed.server%</code> as the package source, then packages from nuget.org are not found.</p>
  
  <p>I tried setting Packages Sources to include both, but it still isn't working for official nuget.org packages.</p>
  
  <pre><code>https://nuget.org/api/v2/
  %teamcity.nuget.feed.server%
  </code></pre>
  
  <p>Is that not the right URL for the nuget.org package source? How do I tell it to use both sources?</p>
  
  <p>I asked this on the <a href="http://devnet.jetbrains.net/message/5469592#5469592" rel="noreferrer">JetBrains Developer discussion board</a>, but haven't gotten any responses. </p>
