title: SSDT Create schema if not exists
body: <p>I am developing sql project using ssdt in vs2017. I want to create new schema only if it doesn't exist. I have to create new schema otherwise I cannot build my project.</p>
  
  <p>The project that I am developing doesn't have specific db so I cannot do schema comparison. The built sql scipt will be called within other application, and the target db will be selected from the application</p>
  
  <p>Regards, </p>
