title: How do I create a new build definition in TFS 2017 across projects
body: <p>We just upgraded from TFS 2013 to TFS 2017 and I was excited to go in and create a new build definition, but I can't seem to do it at the collection level. I can only create a new build definition once I've selected a project and then when defining the Get Sources page I can't seem to access other projects within the collection. The highest level it will allow me to get is the current project. In the Repository drop-down the only option is the current project. How can I create a new build definition across projects in TFS 2017?</p>
