title: Visual Studio .sqlproj always built
body: <p>When I have an SQL Server Database project (<code>.sqlproj</code>) in Visual Studio solution, I notice that that particular project always gets built every time I build the solution even though there is no change in the project files. </p>
  
  <p>This is inconsistent with normal <code>C#</code> project (<code>.csproj</code>) that only gets built when there is any file that changes. </p>
  
  <p>I have tried cranking up the <code>msbuild</code> output verbosity, and it seems to always build that project without special reason.  </p>
  
  <p>Is there a reason why <code>.sqlproj</code> is always built? Is there a way to make it build only when file changes?</p>
