title: Data Project using SSDT, how to reference another database without it populating in same project folder in SS Obj Explorer
body: <p>I have a Database Project in Visual Studio called AMC.</p>
  
  <p>In AMC I have a view, which references an object in another Database (on same instance) called AMC2 that was raising errors in the project; the error was it didn't recognize the AMC2 reference.</p>
  
  <p>So I got the dacpac from AMC2 and added it as a reference. Now my view script doesn't throw errors in the projects as it has a known reference, but in my SQL Server Object Explorer (in Visual Studio), I'm seeing stored procedures and tables etc from the other AMC2 being combined with AMC.</p>
  
  <p>How can I reference AMC2 in my AMC database project without that mixing of db objects happening in the SQL Server Object Explorer under my AMC Project?</p>
