title: Reference DLL file not copying to bin with deployment project, causing error
body: <p>We have several external DLL files being referenced in our Web Application Project. We have a deployment project for installing on the hosting servers. When we were using .NET 3.5 and Visual&nbsp;Studio&nbsp;2008 the DLL files were being copied to the bin folder. Since we have upgraded to .NET 4 and Visual&nbsp;Studio&nbsp;2010 this no longer happens, and we are getting server errors since the references cannot be found.</p>
  
  <p>CopyLocal is set to true, and I cannot find anything inside the web.config which suggests this is being set elsewhere.</p>
