title: NuGet Package Manager for custom project type
body: <p>I am wondering if it is possible to enable the NuGet Package Manager in Visual Studio for custom project types.</p>
  
  <p>I created a custom project type using Visual Studio Project System and when I right click the solution and select <strong>Manage NuGet Packages...</strong> I get the message '<em>Operation Failed. The project '[ProjectName]' is unsupported.</em>'</p>
  
  <p>If I edit the project file and packages.config file in a text editor and run NuGet commands from the command line (restore, update) it works, but I would like to use the same package manager available to CS and VB projects. I hope there is a simple configuration to enable this. </p>
  
  <p>I have seen tutorials on adding default packages to a project type but I want to allow a developer to use the manager to add new packages or update current ones. Anyone have experience doing this?</p>
