title: Programmatically access tfs build output
body: <p>I'm trying to write a powershell script to allow a user to specify a tfs build id (or alternately a changeset id) and download the build output to the current directory. I have the build configured to copy the output to the server, which means only the most recent build output will be accessible in that directory. However from Visual Studio, or from the TFS Web Access, I can download the drop as a .zip file.</p>
  
  <p>How can I access this .zip file programmatically (either in powershell, or even if I could figure out VB code to do this I can convert it to a powershell script)? Am I thinking about build output wrong, and there's a easier, more obvious way to handle this? Is the build output of the older builds being stored somewhere else on the server, or is it store in the database? Should I be configuring the build differently to store each build in a separate folder rather than overwriting each build in a single folder?</p>
