title: Visual Studio: Using external files (without copying them)
body: <p>I want to import an enum class (.cs) into my project that is generated by another service. So if that service will update this file, it should be automatically updated in my project. It has to be text-only (so I can't use an assembly) because we can't compile code in php.</p>
  
  <p>And here is why I want this: 
  We are using global language strings in multiple applications and I would like to use them as enumerations for some reasons. When new texts are added I want to be able to use them without copying or changing anything. Maybe there is another way to achieve this. </p>
  
  <p>Thank you.</p>
